Lesson Purpose

The purpose of this lesson is for students to practice addition and subtraction within 100 that does not require composing or decomposing a ten.

Lesson Narrative

In Activity 1, students learn stage 3 of the Capture Squares center. In this new stage, called Add within 20, students find the value of sums within 20. In Activity 2, students learn stage 6 of the Five in a Row center. In this stage, students practice finding the value of sums within 100 that require composing when adding by place.
