Let's solve the problem step by step. The task is to
estimate the length of each object and
circle the most reasonable measurement in either meters (m) or centimeters (cm).
We’ll go through each item one by one, using real-world knowledge to estimate.
---
1. Block / Brick
- Options:
5 cm or
20 cm
- A typical brick is about
20 cm long.
-
✔ Correct answer: 20 cm
---
2. School Bus
- Options:
1 m or
10 m
- A school bus is about
10 meters long.
-
✔ Correct answer: 10 m
---
3. Loaf of Bread
- Options:
170 cm or
20 cm
- A standard loaf of bread is about
20 cm long, not 170 cm (which is almost 1.7 meters — too long).
-
✔ Correct answer: 20 cm
---
4. Candy
- Options:
3 cm or
15 cm
- A typical wrapped candy bar is about
3 cm long.
-
✔ Correct answer: 3 cm
---
5. Cow
- Options:
2 m or
5 cm
- A cow is about
2 meters tall (from hoof to shoulder), but we're estimating
length — a cow is around
2–3 meters long.
- 5 cm is way too small.
-
✔ Correct answer: 2 m
---
6. Fly
- Options:
8 cm or
1 cm
- A fly is very small — about
1 cm long.
- 8 cm is too big for a fly.
-
✔ Correct answer: 1 cm
---
7. Shark
- Options:
4 cm or
3 m
- A shark is large — even a small shark is several meters long.
- 4 cm is like a finger; 3 meters is realistic.
-
✔ Correct answer: 3 m
---
8. T-shirt
- Options:
7 m or
45 cm
- A t-shirt is about
45 cm wide (or lengthwise, depending on how you measure). 7 meters is way too big — that’s longer than a car!
-
✔ Correct answer: 45 cm
---
