Lesson 7
Numbers With Tens and Ones
Lesson Purpose
The purpose of this lesson is for students to understand that two-digit numbers are composed of tens and ones.
Lesson Narrative
In the previous lesson, students considered different ways to organize, count, and represent a collection of 52 objects.
In this lesson, students generalize the base-ten structure to all two-digit numbers. They read these numbers and consider how they are made up of tens and ones. At this time, students do not need to write two-digit numbers because they will do so in a later lesson.
