Lesson 14

Center Day 3

Lesson Purpose

The purpose of this lesson is for students to practice working with data and adding and subtracting within 10.

Lesson Narrative

Students learn a new center called Sort and Display. In this center, students sort 10–20 objects into two or three categories and then show how they sorted. They show their representation to a partner and ask questions that can be answered about their collection of objects. Students then choose from other center activities introduced in a previous section. This lesson provides the opportunity to formatively assess how students add and subtract within 10.
