5. Estimating and Measuring
1 and 2s will work together and 3s, 4s, and 5s will work together.
Estimate each other’s height.
Record your estimate and color it yellow.
Then use the meter tape to measure each other’s height.

6. Discussion
Look at the measurement on your card and line up from shortest to tallest.
Why do you think some people are out of place?
Let’s see how some people measured each other.

Record your height.
Measure your arm span and compare your height to your arm span.
