#### Capture 4 Addition Game Boards: Making 5, 6, 7, 8, 9, 10, 12, and 20

These Capture 4 game boards focus on all the ways to compose and decompose a single sum, rather than practicing random, unrelated facts. The engaging tic-tac-toe format requires strategic thinking! A Math Talk card is included to support student communication. Digital version included!

#### Addition Strategies: Make a Ten

A strategy-based approach for teaching facts is based on the relationships between addition and subtraction as well as the relationships between facts. This resource includes information and activities related to the Make a Ten Strategy.

#### Composing and Decomposing Fractions with Number Bonds

Students can use their understanding of the part/whole relationship and number bonds to develop a deep understanding of fractions.

## Description

Understanding that numbers can be decomposed by place value in more than one way lays the foundation for making sense of the regrouping necessary for using the standard algorithm for subtraction. When you regroup to solve 85 – 17, you are really decomposing 85 into 7 tens and 15 ones.

These cards are “puzzles” because they force students to decompose numbers in ways other than the traditional hundreds, tens, and ones. They are great for math workstations, but be sure to include base-ten blocks to support student understanding.

Set includes:

• 16 task cards with 2- and 3-digit numbers
• An interactive Google Slides file with the same task cards and movable base-10 pieces.
