Fluency and flexibility with numbers are the hallmarks of mathematical thinking. For our students to develop strong number sense, they must understand how numbers can be composed and decomposed. That’s why learning the combinations for numbers to 10 is a primary focus in our 1st grade classrooms.

These ten frames show four different ways to decompose 7:
6 and 1 make 7
5 + 2 = 7
1 and 6 is 7
7 = 3 + 4
