Unit 2, Lesson 9

Ordering Numbers from Least to Greatest

Massachusetts Department of Elementary and Secondary Education 53 min(s)

In this lesson, children must make greater than/less than judgments relative to random benchmark numbers and to the other numbers they are placing. The task requires them not just to differentiate the tens from the units digit but to strategize when the tens digit alone gives them all the information they need to make a greater than/less than judgment and when they must also take the units digit into account. As you plan, consider the variability of learners in your class and make adaptations as necessary.
