PRODUCT DESCRIPTION

Use these worksheets to solidify the understanding of decomposing 20. 33 differentiated sheets that begin with filling the dots of a given number to adding a number sentence to explaining how they found their answer.

Questions to ask:
How did you count? Did you see any groups? How many numbers did you put together to make 20?

Highlight kids that were able to write number sentences to show the communative property, adding more than one digit together, and grouping by 1s, 2s, and 5s to get their answer, and counting on.

Ex: I see two groups of 2 so I know that there are 4 dots. I need 16 more to make 20, so my number sentence would be 2+2+16 = 20 or 4+16 = 20.

Set up as independent work, small group, remedial understanding of sums of 10, homework or math centers.

Enjoy!
