Help your student become a(n) Composer to 4, then 5

Activities promote meaningful knowledge of all combinations up to totals of 4 and then 5. 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 emphasize visual models and understanding.
