Unit 2, Lesson 7

Comparing Numerals on a Decade Number Line

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

In this lesson children will justify their judgments of greater than/less than using various mathematical place-value models- bean sticks, ten-frames, a blank hundreds board, and a decade number line. By making a connection between their conceptual understanding and various physical models, they will get different perspectives on the concept, thereby making their understanding broader and deeper. As you plan, consider the variability of learners in your class and make adaptations as necessary.
