Let's solve the "Let's Measure!" worksheet step by step. The task is to measure each object to the
nearest centimeter (cm) using the ruler shown beneath each object.
We’ll go through each object one by one and determine its length based on how it aligns with the ruler.
---
1. Candy
- The candy starts at
0 cm.
- It ends just before the
2 cm mark, but not quite reaching it.
- Looking closely: it appears to end
between 1 and 2 cm, closer to
2 cm.
- But since we're measuring to the
nearest cm, we look at whether it’s closer to 1 or 2.
- The candy extends past the
1.5 cm mark, so it's closer to
2 cm.
-
✔ Answer: 2 cm

2. Glasses
- The glasses start at
0 cm.
- The right edge of the glasses reaches just
before 6 cm, but clearly past
5 cm.
- It appears to be about
5.5 cm, which is halfway between 5 and 6.
- Since it's
exactly halfway or more, we round up to the nearest cm.
- So,
5.5 cm → 6 cm.
-
✔ Answer: 6 cm

3. Pencil
- The pencil starts at
0 cm.
- It ends
just after the 8 cm mark, but very close to it.
- The tip goes a little beyond 8 cm, but only slightly — maybe
8.2 cm.
- To the
nearest cm, this rounds to
8 cm.
-
✔ Answer: 8 cm

4. Key
- The key starts at
0 cm.
- It ends
between 3 and 4 cm, but clearly
closer to 3 cm.
- It appears to be around
3.2 cm, which is less than 3.5 cm.
- So, we round down to
3 cm.
-
✔ Answer: 3 cm
---
✔ Final Answers:
1.
Candy:
2 cm
2.
Glasses:
6 cm
3.
Pencil:
8 cm
4.
Key:
3 cm

🔍 How to Measure Correctly:
- Always align the
left end of the object with
0 cm on the ruler.
- Look at where the
right end of the object falls.
- If it's
less than halfway between two numbers, round down.
- If it's
halfway or more, round up.
This is how you estimate to the
nearest centimeter.
