## Other Examples:

- "9 and 9 is 18."
- Shown 10, then 7 are secretly hidden and the remaining 3 are shown, a child quickly says “7 are hidden.”

## Help your student become a(n) Composer to 10

Distributed practice is key to achieving fluency. This means frequent but brief practice with activities that promote meaningful knowledge of all combinations up to totals of 10. Like most composing number levels, they use visual models (conceptual subitizing) and thinking strategies. For example, children understand the ideas of "add (or subtract) zero" (same number) and "add (or subtract) 1" (next or previous number). They also use commutativity (if I know 8 + 2, I know 2 + 8) and associativity (7 + 9 + 1 is 7 + (9 + 1) is 7 + 10 is 17). Activities do not use timed tests and drill without understanding. Group related facts. Choose number combinations that connect to/relate to specific related strategies (+/- 1 or 2; +/- 9 or 10). Ask students to notice patterns they see. Connect addition and subtraction.
