Step-by-step solution for: 3rd Grade Math Worksheets
Let's solve each problem on this 5-A-Day Math Review: Week 2 worksheet step by step, explaining the reasoning behind each answer.
---
#### 1. Multiply
We are multiplying numbers in a table:
- Multiply each number (8, 7, 4) by 30 and 50.
| Multiply | 30 | 50 |
|---------|----------|----------|
| 8 | 8 × 30 = 240 | 8 × 50 = 400 |
| 7 | 7 × 30 = 210 | 7 × 50 = 350 |
| 4 | 4 × 30 = 120 | 4 × 50 = 200 |
✔ Answer:
```
240 400
210 350
120 200
```
---
#### 2. Addition and Subtraction
Solve:
- 97 + 38 =
→ 97 + 30 = 127, then +8 = 135
- 189 - 21 =
→ 189 - 20 = 169, then -1 = 168
- 89 + 36 =
→ 89 + 30 = 119, then +6 = 125
✔ Answers:
```
135
168
125
```
---
#### 3. Complete the fact family
Given: 3 × 4 = ?
- 3 × 4 = 12
- 4 × 3 = 12 (commutative property)
- 12 ÷ 4 = 3
- 12 ÷ 3 = 4
✔ Answers:
```
12
12
3
4
```

#### 4. Area of the figure
Count the number of unit squares.
The shape is made up of:
- Left column: 4 squares tall, 2 wide → 4×2 = 8
- Middle: 3 squares wide, 2 high → 3×2 = 6
- Right: 2 squares wide, 2 high → 2×2 = 4
Wait — better to count directly:
Let’s go row by row from bottom to top:
- Row 1 (bottom): 2 squares
- Row 2: 2 + 2 = 4 squares
- Row 3: 2 + 2 + 2 = 6 squares
- Row 4: 2 + 2 + 2 + 2 = 8 squares? Wait — no, let's look carefully.
Actually, looking at the diagram:
It looks like:
- First column (left): 4 squares (vertical)
- Second column: 4 squares
- Third column: 3 squares
- Fourth column: 3 squares
- Fifth column: 2 squares
- Sixth column: 2 squares
So total:
4 + 4 + 3 + 3 + 2 + 2 = 18 squares
✔ Area = 18 square units

#### 5. Complete the table: bikes and wheels
Each bike has 2 wheels.
| bikes | 1 | 2 | 3 | 4 | 5 | 6 |
|-------|---|---|---|---|---|---|
| wheels| 2 | 4 | 6 | 8 | 10 | 12 |
Pattern: Number of wheels = 2 × number of bikes
✔ Wheels: 6, 8, 10, 12
Pattern: Each bike has 2 wheels, so multiply number of bikes by 2.
---
#### 1. Circle the shapes to model: 8 ÷ 4 = ?
There are 8 basketballs. Divide into 4 equal groups.
- 8 ÷ 4 = 2
- So circle 2 balls in each group (4 groups of 2)
✔ Answer: 2
---
#### 2. Name the fraction
One rectangle is shaded out of three equal parts.
So, the fraction is:
✔ 1/3
---
#### 3. Find the missing numbers
a) 5 × ___ = 20
→ 20 ÷ 5 = 4
b) 5)20 → 20 ÷ 5 = 4
c) 4)12 → 12 ÷ 4 = 3
d) 4 × ___ = 12
→ 12 ÷ 4 = 3
✔ Answers:
- 4
- 4
- 3
- 3
---
#### 4. Partition and shade one-fourth
Draw a square and divide it into 4 equal parts (e.g., 2 rows and 2 columns), then shade one part.
✔ Shade 1 out of 4 equal parts
---
#### 5. Associative Property: Solve and circle shapes
Given:
(2 × 4) × 3 = 2 × (□ × 3)
Left side: (2 × 4) × 3 = 8 × 3 = 24
Right side: 2 × (□ × 3) must also equal 24
So: 2 × (x × 3) = 24 → x × 3 = 12 → x = 4
So fill in: 4
Now, left side: 3 groups of 2×4 = 3 groups of 8 = 24 circles
Right side: 2 groups of (4×3) = 2 groups of 12 = 24 circles
To model:
On the right, we have 2 groups of 12 circles → so circle 4 rows of 3 circles (or group them as 4×3)
✔ Answer: 4
And circle the 4×3 group on the right-hand side.
