Math practice · Week 34 · Monday
I can estimate and measure in inches and centimeters.
Look: measuring a spoon
- Estimate first. Then line up the end with 0.
- Read the number where the object ends.
- Centimeters are small, so the centimeter number is bigger.
Estimate, then measure each object in inches and in centimeters.
| Object | Estimate (inches) | Inches | Centimeters |
|---|---|---|---|
