1. Compose and Decompose to Make Ten Unit of Study: Making a Ten Global Concept Guide: 2 of 2

2. Content Development  Approximately three days should be spent on students developing an understanding and investigating the ways to compose and decompose 10.  Students should have multiple opportunities to build and break apart ten using a variety of tools. (i.e. tens frames, snap cubes, cuisenaire rods, chain links)  Ten frames play a vital role in helping students develop a visual image of the number pairs that make ten.

3. Day 1  The focus of Day 1 is for students to count on from any given number to make a ten.  Provide students opportunities to recognize numbers as visual representations of a number (0-10) and build the number ten with counting on from the given number. 2 4 76 89 10

4. Day 2  The focus of Day 2 provides students exploration time with tools to find the different ways ten can be composed and decomposed.  Use open ended problem solving scenarios such as:  Mrs. John’s class was playing kickball. There were 10 students playing in all. How many girls were playing? How many boys?  Students can create foldables or use notebooks to record their learning.

5. Day 3  The focus of Day 3 reinforces composing and decomposing all of the number bonds for 10.  Provide students with tools that can be snapped together/taken apart to model the multiple number pairs that form 10.  Create a class anchor chart with students findings.
