Step-by-step solution for: Properties of Materials online pdf worksheet
Let's solve this worksheet step by step.
---
Task: Match each object with the most suitable material property from the list.
We are given:
- Objects: Pillow, Sweater, Jar, Paper bag, Ring, Plastic hose, Durian, Pipe, Rubber mat, Balloons
- Properties to choose from: Soft, Weak, Waterproof, Rough, Smooth, Lightweight, Flexible, Shiny, Strong, Transparent
We need to match each object with one or more appropriate properties. Since it’s a Grade 1 worksheet, we’ll pick one main property for each object that best describes its material.
---
#### 1. Pillow
- Made of soft fabric and stuffing.
- Best property: ✔ Soft
#### 2. Sweater
- Usually made of wool or cotton; warm and flexible.
- It can be soft and stretchy.
- Best property: ✔ Soft (also could be flexible, but "soft" is most basic)
#### 3. Jar
- Typically made of glass.
- Glass is clear and smooth.
- Best property: ✔ Transparent (since you can see through it)
*(Also smooth, but transparent is more unique to glass)*
#### 4. Paper bag
- Made of paper; light and easy to carry.
- Best property: ✔ Lightweight
#### 5. Ring
- Usually made of metal (like gold or silver).
- Metals are shiny.
- Best property: ✔ Shiny
#### 6. Plastic hose
- Made of plastic; can bend easily.
- Best property: ✔ Flexible
#### 7. Durian
- The outer shell is very spiky and rough.
- Best property: ✔ Rough
#### 8. Pipe
- Metal pipes are strong and used to carry water or gas.
- Best property: ✔ Strong
#### 9. Rubber mat
- Made of rubber; waterproof and often used in bathrooms or gyms.
- Best property: ✔ Waterproof (also flexible, but waterproof is key)
#### 10. Balloons
- Made of latex or plastic; stretchable and thin.
- They are usually not strong, but they are flexible.
- Also, they can be translucent, but "flexible" is more accurate.
- Best property: ✔ Flexible
Wait — let’s double-check balloons. Are they waterproof? Yes, they can hold air/water without leaking → Waterproof is also valid.
But flexible is better because they stretch and bend easily.
However, waterproof is a good choice too. But since only one match per item is expected, let's go with Flexible, as it’s more about the material behavior.
But wait — plastic hose is already matched to Flexible, so maybe Balloons should go with Waterproof?
Let’s re-evaluate:
- Plastic hose: Flexible ✔
- Balloons: Can be filled with water — waterproof ✔
- But rubber mat is also waterproof.
So both rubber mat and balloons are waterproof.
But let’s look at what’s left after matching others.
Let’s do a full matching table:
---
| Object | Best Property |
|----------------|----------------------|
| Pillow | Soft |
| Sweater | Soft |
| Jar | Transparent |
| Paper bag | Lightweight |
| Ring | Shiny |
| Plastic hose | Flexible |
| Durian | Rough |
| Pipe | Strong |
| Rubber mat | Waterproof |
| Balloons | Flexible? Or Water proof? |
Wait — plastic hose is already Flexible, and balloons are also Flexible.
But rubber mat is Waterproof, which makes sense.
But balloons are not necessarily strong — they burst easily.
They are lightweight? Yes, but so is paper bag.
Let’s reconsider:
- Balloons → made of rubber/plastic → Flexible, Waterproof, Lightweight
- But paper bag is Lightweight
- Plastic hose is Flexible
- Rubber mat is Waterproof
So perhaps:
- Balloons → Flexible (they stretch)
- Rubber mat → Waterproof (used on wet floors)
- Plastic hose → Flexible — but same as balloons?
Hmm — maybe two items can share a property? But typically in such worksheets, one-to-one matching is expected.
Let’s count:
- Objects: 10
- Properties: 10
So likely one property per object.
Let’s list all properties:
1. Soft
2. Weak
3. Waterproof
4. Rough
5. Smooth
6. Lightweight
7. Flexible
8. Shiny
9. Strong
10. Transparent
Now assign uniquely:
1. Pillow → Soft ✔
2. Sweater → Soft ✘ (duplicate) → Wait! We can't use “Soft” twice.
Ah! Problem: Two objects might have the same property, but if there are 10 objects and 10 properties, then each property is used once.
So we must choose different properties for each object.
So Soft can only be used once.
Therefore, either pillow or sweater gets "Soft", but not both.
Let’s rethink.
Perhaps sweater is Flexible? Yes, sweaters stretch.
Pillow is Soft.
Sweater → Flexible? Possible.
But plastic hose is also flexible.
Wait — let’s list possible matches carefully.
---
Let’s go through each object and pick one best-fit property, avoiding duplicates.
---
1. Pillow → made of soft material → ✔ Soft
2. Sweater → knitted fabric → can stretch → ✔ Flexible
3. Jar → glass → clear → ✔ Transparent
4. Paper bag → made of paper → lightweight → ✔ Lightweight
5. Ring → metal → shiny → ✔ Shiny
6. Plastic hose → bends easily → ✔ Flexible → but sweater is also flexible!
Conflict.
So can’t have two "Flexible".
Alternative: Plastic hose → Waterproof? Yes, plastic prevents water from passing → ✔ Waterproof
Then rubber mat → also waterproof?
But only one waterproof.
Let’s think:
- Plastic hose → Waterproof ✔ (can carry water without leaking)
- Rubber mat → Waterproof ✔ (used in showers)
- Balloons → Waterproof ✔ (hold water)
So three items could be waterproof.
But only one slot.
So we need to pick the most representative.
But the worksheet likely allows multiple matches per object? No — it says “match with the suitable properties”, and there are 10 boxes, 10 items.
So probably each object gets one property, and each property used once.
So we need to pick one property per object, no repeats.
Let’s list:
| Object | Best Fit Property | Reason |
|----------------|-------------------|--------|
| Pillow | Soft | Very soft to touch |
| Sweater | Flexible | Stretches when worn |
| Jar | Transparent | You can see through glass |
| Paper bag | Lightweight | Easy to carry |
| Ring | Shiny | Reflects light |
| Plastic hose | Flexible | Bends easily |
| Durian | Rough | Spiky outer shell |
| Pipe | Strong | Metal pipes are strong |
| Rubber mat | Waterproof | Used in wet areas |
| Balloons | ? | Leftover property: Weak or Smooth or Waterproof |
Wait — we have 10 properties:
1. Soft
2. Weak
3. Waterproof
4. Rough
5. Smooth
6. Lightweight
7. Flexible
8. Shiny
9. Strong
10. Transparent
Used so far:
- Soft → Pillow ✔
- Flexible → Sweater ✔
- Transparent → Jar ✔
- Lightweight → Paper bag ✔
- Shiny → Ring ✔
- Flexible → Plastic hose ✘ (conflict!)
Problem: Sweater and Plastic hose both want "Flexible"
So we must choose one.
Let’s try:
- Plastic hose → Flexible ✔ (best fit)
- Sweater → Soft ✔ (also fits well)
But Pillow is also soft.
So conflict between Pillow and Sweater for "Soft"
So we need to decide: which is more soft?
Both are soft, but pillow is specifically designed to be soft.
Sweater is soft, but also flexible and warm
So perhaps:
- Pillow → Soft
- Sweater → Flexible
- Plastic hose → Flexible → still conflict
No — only one "Flexible"
So we must pick one object for "Flexible"
Which is most flexible?
- Plastic hose → bends easily, very flexible
- Sweater → stretches, but limited
- Balloons → stretch a lot → very flexible
So Balloons are extremely flexible.
Maybe Balloons → Flexible
Then:
- Plastic hose → Waterproof (it carries water, doesn’t leak)
- Rubber mat → Waterproof → conflict again
Alternatively:
- Rubber mat → Waterproof
- Plastic hose → Flexible
- Balloons → Lightweight? Possible, but paper bag is lighter
Balloons → Smooth? Yes, surface is smooth
Plastic hose → Smooth? Yes, plastic is smooth
But jar is already transparent
Let’s try a new approach.
---
Let’s assign each object to one property, no repeats.
1. Pillow → Soft ✔
2. Sweater → Flexible ✔ (stretches)
3. Jar → Transparent ✔
4. Paper bag → Lightweight ✔
5. Ring → Shiny ✔
6. Plastic hose → Waterproof ✔ (doesn’t leak water)
7. Durian → Rough ✔ (spiky shell)
8. Pipe → Strong ✔ (metal pipe supports pressure)
9. Rubber mat → Flexible ✘ (already used) → no
Wait — Rubber mat is flexible and waterproof.
But plastic hose is already waterproof.
Can we give rubber mat → Flexible?
But sweater has flexible.
So only one flexible.
So who should get Flexible?
- Plastic hose → very flexible
- Balloons → very stretchy
- Sweater → somewhat flexible
Best: Balloons → Flexible
Then:
- Plastic hose → Waterproof
- Rubber mat → Waterproof → conflict
Only one Waterproof
So pick the most waterproof:
- Plastic hose → holds water → waterproof
- Rubber mat → keeps floor dry → waterproof
- Balloons → hold water → waterproof
All three are waterproof.
But only one slot.
So we must pick the best one.
But rubber mat is designed to be waterproof (for bathrooms), so it’s a good fit.
Plastic hose is made of plastic → waterproof
Balloons are thin, but still waterproof
But rubber mat is thick and durable → excellent waterproof
So maybe:
- Rubber mat → Waterproof
- Plastic hose → Flexible
- Balloons → Lightweight or Smooth
But paper bag is already lightweight
Balloons → Smooth? Yes, surface is smooth
Plastic hose → Smooth? Yes
But jar is transparent, not smooth
So smooth is available
Let’s try:
| Object | Property |
|----------------|----------------|
| Pillow | Soft |
| Sweater | Flexible |
| Jar | Transparent |
| Paper bag | Lightweight |
| Ring | Shiny |
| Plastic hose | Flexible | → conflict with sweater
No.
Let’s try:
- Balloons → Flexible
- Sweater → Soft
- Pillow → Soft → conflict
Still problem.
Unless both sweater and pillow are soft — but only one "Soft" box.
So the worksheet may allow multiple matches for one property? But layout suggests one line per property.
Looking at the image: There are 10 properties listed in a column, and 10 objects.
Likely: Each object is matched to one property, and each property used once.
So we must assign uniquely.
Let’s list all 10 properties:
1. Soft
2. Weak
3. Waterproof
4. Rough
5. Smooth
6. Lightweight
7. Flexible
8. Shiny
9. Strong
10. Transparent
Now assign:
1. Pillow → Soft ✔
2. Sweater → Flexible ✔
3. Jar → Transparent ✔
4. Paper bag → Lightweight ✔
5. Ring → Shiny ✔
6. Plastic hose → Flexible ✘ (duplicate) → not allowed
So instead, Plastic hose → Waterproof ✔
Then Rubber mat → Waterproof ✘
So only one Waterproof
Let’s give Rubber mat → Waterproof ✔
Then Plastic hose → Flexible ✔
Then Balloons → Flexible ✘
No.
Alternative idea:
- Balloons → Weak? Yes, they pop easily → ✔ Weak
- Plastic hose → Flexible ✔
- Rubber mat → Waterproof ✔
- Sweater → Soft ✔
- Pillow → Soft ✘
Still conflict.
Wait — maybe Pillow is Soft, Sweater is Soft — but both are soft.
But only one "Soft" property.
So perhaps the worksheet allows multiple items to be matched to the same property.
But visually, it looks like each property is a box to be connected to one object.
But in many such worksheets, properties can be reused.
But here, there are 10 objects and 10 properties — likely one-to-one.
So we must find a way.
Let’s try this:
Let’s assume some properties can be shared, but since there are 10 boxes and 10 items, likely one per item.
But some properties apply to multiple.
For example:
- Soft: Pillow, Sweater
- Flexible: Sweater, Plastic hose, Balloons
- Waterproof: Plastic hose, Rubber mat, Balloons
So perhaps the intention is to match one property per object, and properties can be reused.
But the format shows 10 separate boxes, so likely each property is used once.
So we must pick the most appropriate for each.
Let’s try:
1. Pillow → Soft ✔
2. Sweater → Flexible ✔
3. Jar → Transparent ✔
4. Paper bag → Lightweight ✔
5. Ring → Shiny ✔
6. Plastic hose → Waterproof ✔
7. Durian → Rough ✔
8. Pipe → Strong ✔
9. Rubber mat → Flexible ✔
10. Balloons → Weak ✔
Now check properties used:
- Soft ✔ (Pillow)
- Flexible ✔ (Sweater)
- Transparent ✔ (Jar)
- Lightweight ✔ (Paper bag)
- Shiny ✔ (Ring)
- Waterproof ✔ (Plastic hose)
- Rough ✔ (Durian)
- Strong ✔ (Pipe)
- Flexible ✔ (Rubber mat) → duplicate!
- Weak ✔ (Balloons)
Oh — Flexible used twice.
Not allowed.
So change Rubber mat → Smooth? Yes, rubber mats are smooth.
Then:
- Rubber mat → Smooth ✔
- Plastic hose → Flexible ✔
- Sweater → Soft ✔
- Pillow → Soft ✘
Still conflict.
Wait — if Sweater is Soft, then Pillow cannot be.
But Pillow is more soft than sweater.
So perhaps:
- Pillow → Soft ✔
- Sweater → Flexible ✔
- Plastic hose → Flexible ✘
No.
Final solution: accept that some properties are used for multiple items, or the worksheet allows it.
But in practice, for Grade 1, they might expect:
1. Pillow → Soft
2. Sweater → Soft
3. Jar → Transparent
4. Paper bag → Lightweight
5. Ring → Shiny
6. Plastic hose → Flexible
7. Durian → Rough
8. Pipe → Strong
9. Rubber mat → Waterproof
10. Balloons → Flexible
But now Flexible used twice.
Alternatively:
- Balloons → Weak (they burst easily)
- Plastic hose → Flexible
- Rubber mat → Waterproof
- Sweater → Soft
- Pillow → Soft → still duplicate
So the only way is to accept that Soft applies to both pillow and sweater.
Similarly, Flexible to multiple.
But since the worksheet has 10 boxes, likely intended for one-to-one.
After research, common solutions for such worksheets allow one property per object, and properties can be reused.
But here, since there are 10 properties and 10 objects, and no indication of reuse, we must pick.
Let’s try:
1. Pillow → Soft
2. Sweater → Flexible
3. Jar → Transparent
4. Paper bag → Lightweight
5. Ring → Shiny
6. Plastic hose → Waterproof
7. Durian → Rough
8. Pipe → Strong
9. Rubber mat → Smooth
10. Balloons → Weak
Now check properties used:
- Soft ✔
- Flexible ✔
- Transparent ✔
- Lightweight ✔
- Shiny ✔
- Waterproof ✔
- Rough ✔
- Strong ✔
- Smooth ✔
- Weak ✔
All properties used once.
And each object has one.
Now verify:
- Rubber mat → Smooth? Yes, surface is smooth.
- Balloons → Weak? Yes, they pop easily.
- Plastic hose → Waterproof? Yes, doesn’t leak.
- Sweater → Flexible? Yes, stretches.
- Pillow → Soft? Yes.
Perfect.
So final answer:
---
| Object | Property |
|----------------|----------------|
| Pillow | Soft |
| Sweater | Flexible |
| Jar | Transparent |
| Paper bag | Lightweight |
| Ring | Shiny |
| Plastic hose | Waterproof |
| Durian | Rough |
| Pipe | Strong |
| Rubber mat | Smooth |
| Balloons | Weak |
---
- Pillow is soft because it is filled with cushioning material.
- Sweater is flexible because it stretches when worn.
- Jar is transparent because you can see through the glass.
- Paper bag is lightweight because it is made of thin paper.
- Ring is shiny because it reflects light (usually made of metal).
- Plastic hose is waterproof because it doesn’t let water pass through.
- Durian is rough because its outer shell has sharp spikes.
- Pipe is strong because it can withstand pressure.
- Rubber mat is smooth because its surface is flat and even.
- Balloons are weak because they burst easily when overfilled or punctured.
This matching uses each property exactly once and fits the materials' properties accurately for a Grade 1 level.

Worksheet – Materials (Grade 1)
Task: Match each object with the most suitable material property from the list.
We are given:
- Objects: Pillow, Sweater, Jar, Paper bag, Ring, Plastic hose, Durian, Pipe, Rubber mat, Balloons
- Properties to choose from: Soft, Weak, Waterproof, Rough, Smooth, Lightweight, Flexible, Shiny, Strong, Transparent
We need to match each object with one or more appropriate properties. Since it’s a Grade 1 worksheet, we’ll pick one main property for each object that best describes its material.

Step-by-step Matching:
#### 1. Pillow

#### 2. Sweater
- Usually made of wool or cotton; warm and flexible.
- It can be soft and stretchy.
- Best property: ✔ Soft (also could be flexible, but "soft" is most basic)

- Glass is clear and smooth.
- Best property: ✔ Transparent (since you can see through it)
*(Also smooth, but transparent is more unique to glass)*
#### 4. Paper bag
- Made of paper; light and easy to carry.
- Best property: ✔ Lightweight

- Best property: ✔ Flexible
#### 7. Durian
- The outer shell is very spiky and rough.
- Best property: ✔ Rough
#### 8. Pipe
- Metal pipes are strong and used to carry water or gas.
- Best property: ✔ Strong
#### 9. Rubber mat

#### 10. Balloons
- Made of latex or plastic; stretchable and thin.
- They are usually not strong, but they are flexible.
- Also, they can be translucent, but "flexible" is more accurate.
- Best property: ✔ Flexible
Wait — let’s double-check balloons. Are they waterproof? Yes, they can hold air/water without leaking → Waterproof is also valid.
But flexible is better because they stretch and bend easily.
However, waterproof is a good choice too. But since only one match per item is expected, let's go with Flexible, as it’s more about the material behavior.
But wait — plastic hose is already matched to Flexible, so maybe Balloons should go with Waterproof?
Let’s re-evaluate:
- Plastic hose: Flexible ✔
- Balloons: Can be filled with water — waterproof ✔
- But rubber mat is also waterproof.
So both rubber mat and balloons are waterproof.
But let’s look at what’s left after matching others.
Let’s do a full matching table:
---
✔ Final Matching:
| Object | Best Property |
|----------------|----------------------|
| Pillow | Soft |
| Sweater | Soft |
| Jar | Transparent |
| Paper bag | Lightweight |
| Ring | Shiny |
| Plastic hose | Flexible |
| Durian | Rough |
| Pipe | Strong |
| Rubber mat | Waterproof |
| Balloons | Flexible? Or Water proof? |
Wait — plastic hose is already Flexible, and balloons are also Flexible.
But rubber mat is Waterproof, which makes sense.
But balloons are not necessarily strong — they burst easily.
They are lightweight? Yes, but so is paper bag.
Let’s reconsider:
- Balloons → made of rubber/plastic → Flexible, Waterproof, Lightweight
- But paper bag is Lightweight
- Plastic hose is Flexible
- Rubber mat is Waterproof
So perhaps:
- Balloons → Flexible (they stretch)
- Rubber mat → Waterproof (used on wet floors)
- Plastic hose → Flexible — but same as balloons?
Hmm — maybe two items can share a property? But typically in such worksheets, one-to-one matching is expected.
Let’s count:
- Objects: 10
- Properties: 10
So likely one property per object.
Let’s list all properties:
1. Soft
2. Weak
3. Waterproof
4. Rough
5. Smooth
6. Lightweight
7. Flexible
8. Shiny
9. Strong
10. Transparent
Now assign uniquely:
Let’s try again with careful assignment:
1. Pillow → Soft ✔
2. Sweater → Soft ✘ (duplicate) → Wait! We can't use “Soft” twice.
Ah! Problem: Two objects might have the same property, but if there are 10 objects and 10 properties, then each property is used once.
So we must choose different properties for each object.
So Soft can only be used once.
Therefore, either pillow or sweater gets "Soft", but not both.
Let’s rethink.
Perhaps sweater is Flexible? Yes, sweaters stretch.
Pillow is Soft.
Sweater → Flexible? Possible.
But plastic hose is also flexible.
Wait — let’s list possible matches carefully.
---
Reassigning with uniqueness:
Let’s go through each object and pick one best-fit property, avoiding duplicates.
---
1. Pillow → made of soft material → ✔ Soft
2. Sweater → knitted fabric → can stretch → ✔ Flexible
3. Jar → glass → clear → ✔ Transparent
4. Paper bag → made of paper → lightweight → ✔ Lightweight
5. Ring → metal → shiny → ✔ Shiny
6. Plastic hose → bends easily → ✔ Flexible → but sweater is also flexible!
Conflict.
So can’t have two "Flexible".
Alternative: Plastic hose → Waterproof? Yes, plastic prevents water from passing → ✔ Waterproof
Then rubber mat → also waterproof?
But only one waterproof.
Let’s think:
- Plastic hose → Waterproof ✔ (can carry water without leaking)
- Rubber mat → Waterproof ✔ (used in showers)
- Balloons → Waterproof ✔ (hold water)
So three items could be waterproof.
But only one slot.
So we need to pick the most representative.
But the worksheet likely allows multiple matches per object? No — it says “match with the suitable properties”, and there are 10 boxes, 10 items.
So probably each object gets one property, and each property used once.
So we need to pick one property per object, no repeats.
Let’s list:
Step 1: Assign based on strongest match
| Object | Best Fit Property | Reason |
|----------------|-------------------|--------|
| Pillow | Soft | Very soft to touch |
| Sweater | Flexible | Stretches when worn |
| Jar | Transparent | You can see through glass |
| Paper bag | Lightweight | Easy to carry |
| Ring | Shiny | Reflects light |
| Plastic hose | Flexible | Bends easily |
| Durian | Rough | Spiky outer shell |
| Pipe | Strong | Metal pipes are strong |
| Rubber mat | Waterproof | Used in wet areas |
| Balloons | ? | Leftover property: Weak or Smooth or Waterproof |
Wait — we have 10 properties:
1. Soft
2. Weak
3. Waterproof
4. Rough
5. Smooth
6. Lightweight
7. Flexible
8. Shiny
9. Strong
10. Transparent
Used so far:
- Soft → Pillow ✔
- Flexible → Sweater ✔
- Transparent → Jar ✔
- Lightweight → Paper bag ✔
- Shiny → Ring ✔
- Flexible → Plastic hose ✘ (conflict!)
Problem: Sweater and Plastic hose both want "Flexible"
So we must choose one.
Let’s try:
- Plastic hose → Flexible ✔ (best fit)
- Sweater → Soft ✔ (also fits well)
But Pillow is also soft.
So conflict between Pillow and Sweater for "Soft"
So we need to decide: which is more soft?
Both are soft, but pillow is specifically designed to be soft.
Sweater is soft, but also flexible and warm
So perhaps:
- Pillow → Soft
- Sweater → Flexible
- Plastic hose → Flexible → still conflict
No — only one "Flexible"
So we must pick one object for "Flexible"
Which is most flexible?
- Plastic hose → bends easily, very flexible
- Sweater → stretches, but limited
- Balloons → stretch a lot → very flexible
So Balloons are extremely flexible.
Maybe Balloons → Flexible
Then:
- Plastic hose → Waterproof (it carries water, doesn’t leak)
- Rubber mat → Waterproof → conflict again
Alternatively:
- Rubber mat → Waterproof
- Plastic hose → Flexible
- Balloons → Lightweight? Possible, but paper bag is lighter
Balloons → Smooth? Yes, surface is smooth
Plastic hose → Smooth? Yes, plastic is smooth
But jar is already transparent
Let’s try a new approach.

Final Assignment (unique properties):
Let’s assign each object to one property, no repeats.
1. Pillow → Soft ✔
2. Sweater → Flexible ✔ (stretches)
3. Jar → Transparent ✔
4. Paper bag → Lightweight ✔
5. Ring → Shiny ✔
6. Plastic hose → Waterproof ✔ (doesn’t leak water)
7. Durian → Rough ✔ (spiky shell)
8. Pipe → Strong ✔ (metal pipe supports pressure)
9. Rubber mat → Flexible ✘ (already used) → no
Wait — Rubber mat is flexible and waterproof.
But plastic hose is already waterproof.
Can we give rubber mat → Flexible?
But sweater has flexible.
So only one flexible.
So who should get Flexible?
- Plastic hose → very flexible
- Balloons → very stretchy
- Sweater → somewhat flexible
Best: Balloons → Flexible
Then:
- Plastic hose → Waterproof
- Rubber mat → Waterproof → conflict
Only one Waterproof
So pick the most waterproof:
- Plastic hose → holds water → waterproof
- Rubber mat → keeps floor dry → waterproof
- Balloons → hold water → waterproof
All three are waterproof.
But only one slot.
So we must pick the best one.
But rubber mat is designed to be waterproof (for bathrooms), so it’s a good fit.
Plastic hose is made of plastic → waterproof
Balloons are thin, but still waterproof
But rubber mat is thick and durable → excellent waterproof
So maybe:
- Rubber mat → Waterproof
- Plastic hose → Flexible
- Balloons → Lightweight or Smooth
But paper bag is already lightweight
Balloons → Smooth? Yes, surface is smooth
Plastic hose → Smooth? Yes
But jar is transparent, not smooth
So smooth is available
Let’s try:
| Object | Property |
|----------------|----------------|
| Pillow | Soft |
| Sweater | Flexible |
| Jar | Transparent |
| Paper bag | Lightweight |
| Ring | Shiny |
| Plastic hose | Flexible | → conflict with sweater
No.
Let’s try:
- Balloons → Flexible
- Sweater → Soft
- Pillow → Soft → conflict
Still problem.
Unless both sweater and pillow are soft — but only one "Soft" box.
So the worksheet may allow multiple matches for one property? But layout suggests one line per property.
Looking at the image: There are 10 properties listed in a column, and 10 objects.
Likely: Each object is matched to one property, and each property used once.
So we must assign uniquely.
Let’s list all 10 properties:
1. Soft
2. Weak
3. Waterproof
4. Rough
5. Smooth
6. Lightweight
7. Flexible
8. Shiny
9. Strong
10. Transparent
Now assign:
1. Pillow → Soft ✔
2. Sweater → Flexible ✔
3. Jar → Transparent ✔
4. Paper bag → Lightweight ✔
5. Ring → Shiny ✔
6. Plastic hose → Flexible ✘ (duplicate) → not allowed
So instead, Plastic hose → Waterproof ✔
Then Rubber mat → Waterproof ✘
So only one Waterproof
Let’s give Rubber mat → Waterproof ✔
Then Plastic hose → Flexible ✔
Then Balloons → Flexible ✘
No.
Alternative idea:
- Balloons → Weak? Yes, they pop easily → ✔ Weak
- Plastic hose → Flexible ✔
- Rubber mat → Waterproof ✔
- Sweater → Soft ✔
- Pillow → Soft ✘
Still conflict.
Wait — maybe Pillow is Soft, Sweater is Soft — but both are soft.
But only one "Soft" property.
So perhaps the worksheet allows multiple items to be matched to the same property.
But visually, it looks like each property is a box to be connected to one object.
But in many such worksheets, properties can be reused.
But here, there are 10 objects and 10 properties — likely one-to-one.
So we must find a way.
Let’s try this:
Final Decision:
Let’s assume some properties can be shared, but since there are 10 boxes and 10 items, likely one per item.
But some properties apply to multiple.
For example:
- Soft: Pillow, Sweater
- Flexible: Sweater, Plastic hose, Balloons
- Waterproof: Plastic hose, Rubber mat, Balloons
So perhaps the intention is to match one property per object, and properties can be reused.
But the format shows 10 separate boxes, so likely each property is used once.
So we must pick the most appropriate for each.
Let’s try:
1. Pillow → Soft ✔
2. Sweater → Flexible ✔
3. Jar → Transparent ✔
4. Paper bag → Lightweight ✔
5. Ring → Shiny ✔
6. Plastic hose → Waterproof ✔
7. Durian → Rough ✔
8. Pipe → Strong ✔
9. Rubber mat → Flexible ✔
10. Balloons → Weak ✔
Now check properties used:
- Soft ✔ (Pillow)
- Flexible ✔ (Sweater)
- Transparent ✔ (Jar)
- Lightweight ✔ (Paper bag)
- Shiny ✔ (Ring)
- Waterproof ✔ (Plastic hose)
- Rough ✔ (Durian)
- Strong ✔ (Pipe)
- Flexible ✔ (Rubber mat) → duplicate!
- Weak ✔ (Balloons)
Oh — Flexible used twice.
Not allowed.
So change Rubber mat → Smooth? Yes, rubber mats are smooth.
Then:
- Rubber mat → Smooth ✔
- Plastic hose → Flexible ✔
- Sweater → Soft ✔
- Pillow → Soft ✘
Still conflict.
Wait — if Sweater is Soft, then Pillow cannot be.
But Pillow is more soft than sweater.
So perhaps:
- Pillow → Soft ✔
- Sweater → Flexible ✔
- Plastic hose → Flexible ✘
No.
Final solution: accept that some properties are used for multiple items, or the worksheet allows it.
But in practice, for Grade 1, they might expect:
Recommended Matching (with possible reuse):
1. Pillow → Soft
2. Sweater → Soft
3. Jar → Transparent
4. Paper bag → Lightweight
5. Ring → Shiny
6. Plastic hose → Flexible
7. Durian → Rough
8. Pipe → Strong
9. Rubber mat → Waterproof
10. Balloons → Flexible
But now Flexible used twice.
Alternatively:
- Balloons → Weak (they burst easily)
- Plastic hose → Flexible
- Rubber mat → Waterproof
- Sweater → Soft
- Pillow → Soft → still duplicate
So the only way is to accept that Soft applies to both pillow and sweater.
Similarly, Flexible to multiple.
But since the worksheet has 10 boxes, likely intended for one-to-one.
After research, common solutions for such worksheets allow one property per object, and properties can be reused.
But here, since there are 10 properties and 10 objects, and no indication of reuse, we must pick.
Best possible unique assignment:
Let’s try:
1. Pillow → Soft
2. Sweater → Flexible
3. Jar → Transparent
4. Paper bag → Lightweight
5. Ring → Shiny
6. Plastic hose → Waterproof
7. Durian → Rough
8. Pipe → Strong
9. Rubber mat → Smooth
10. Balloons → Weak
Now check properties used:
- Soft ✔
- Flexible ✔
- Transparent ✔
- Lightweight ✔
- Shiny ✔
- Waterproof ✔
- Rough ✔
- Strong ✔
- Smooth ✔
- Weak ✔
All properties used once.
And each object has one.
Now verify:
- Rubber mat → Smooth? Yes, surface is smooth.
- Balloons → Weak? Yes, they pop easily.
- Plastic hose → Waterproof? Yes, doesn’t leak.
- Sweater → Flexible? Yes, stretches.
- Pillow → Soft? Yes.
Perfect.
So final answer:
---
✔ Answer Key:
| Object | Property |
|----------------|----------------|
| Pillow | Soft |
| Sweater | Flexible |
| Jar | Transparent |
| Paper bag | Lightweight |
| Ring | Shiny |
| Plastic hose | Waterproof |
| Durian | Rough |
| Pipe | Strong |
| Rubber mat | Smooth |
| Balloons | Weak |

Explanation:
- Pillow is soft because it is filled with cushioning material.
- Sweater is flexible because it stretches when worn.
- Jar is transparent because you can see through the glass.
- Paper bag is lightweight because it is made of thin paper.
- Ring is shiny because it reflects light (usually made of metal).
- Plastic hose is waterproof because it doesn’t let water pass through.
- Durian is rough because its outer shell has sharp spikes.
- Pipe is strong because it can withstand pressure.
- Rubber mat is smooth because its surface is flat and even.
- Balloons are weak because they burst easily when overfilled or punctured.
This matching uses each property exactly once and fits the materials' properties accurately for a Grade 1 level.
