Directions for COMPOSING AND DECOMPOSING 3-10
This is a fun and easy way to reinforce composing and decomposing numbers. My students love making the different combinations. They are always told to choose 2 colors and which ever color they start with they must use first for the entire page. This makes the task so much easier. After students figure out the combinations, they fill in the different facts for each number below. If students need manipulatives in the beginning that is fine too.

CCSS.Math.Content.K.OA.A.3 Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).
CCSS.Math.Content.K.NBT.A.1 Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (such as 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
