Help students understand number combinations, number composition, and the commutative property by using these popcorn, movie-themed math facts sorts.
Each set of facts (sums of 5-20) comes with a separate popcorn box and recording sheet. Students sort math facts based on their sum, showing different ways to make the same number.
Additionally, each number includes a worksheet focusing on the different ways to make that number. Each worksheet includes a group-type word problem to reinforce the addition skills in context.
