Unit 6, Lesson 14
Center Day 3 (Optional)
Grade 2
Preparation
Lesson Purpose
The purpose of this lesson is for students to recognize shapes, to describe the attributes of shapes, and to practice adding and subtracting within 100.
Lesson Narrative
This lesson is optional because it is an opportunity for extra practice that not all classes may need. In Activity 1, students revisit Stage 3 of the Picture Books center. This center was first introduced in Kindergarten, and this stage was introduced in Grade 1. In this stage, called Picture Books—Find Shapes, students describe, draw, and name shapes. As students learn more ways to describe shapes and their attributes, the shapes that they notice and how they describe and name them may change. In Activity 2, students choose to continue working on Picture Books, or choose between two previously introduced centers focused on adding and subtracting within 100.
- Name (orally and in writing) shapes found in picture books, based on their attributes.
- Let’s notice shapes in books, and practice adding and subtracting.
Required Preparation
Activity 1
Each group of students needs 2–4 picture books that show a variety of shapes.
Activity 2
Gather materials from:
- Capture Squares, Stages 3 and 4
- Number Puzzles, Stages 2–4
- Picture Books, Stage 3

NoneTeacher Reflection Questions
Think about which students haven’t shared their strategies in class lately. Were there missed opportunities to highlight their thinking during recent lessons? How can you take advantage of those opportunities when they arise?
