Use these worksheets to solidify the understanding of decomposing 10. 22 differentiated sheets that begin with dots aligned next to one another to clearly show 2 separate ways to make 10 and then advance to sheets with unaligned dots to make 10.
Questions to ask:
How did you count? Did you see any groups? How many numbers did you put together to make 10?
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 6 more to make 10, so my number sentence would be 2+2+6 = 10 or 4+6 = 10.
Set up as independent work, small group, remedial understanding of sums of 10, homework or math centers.
