Eureka Math Grade 2 Module 2 Lesson 9 Problem Set Answer Key
Question 1.
Complete the chart by first estimating the measurement
around a classmate’s body part and then finding the actual
measurement with a meter strip.
Explanation:
Completed the chart by first estimating the measurement
around a classmate’s body part and then finding the actual
measurement with a meter strip as shown above.
a. Which was longer, your estimate or the actual measurement
around your classmate’s head? _Actual measurement___
Answer:
The actual measurement around my classmate’s head
is longer than my estimate,
Explanation:
As seen the chart the actual measurement around my
classmate’s head is longer than my estimate because
actual measurement around my classmate’s head is
54 cm and my estimate is 45 cm only,
So by 9 cm the actual measurement around my
classmate’s head is longer than my estimate.
b. Draw a tape diagram to compare the lengths of two different body parts.
