How Many? activity cards build perceptual and conceptual subitizing skills with simple dot patterns on up to larger sets of dots in array and symmetrical patterns. Putting these dots into a grid format allows students to see the patterns and conceptually subitize larger numbers with great precision and speed. The Level 3 set presents dot patterns up to 100.

These card decks are great for small group practice like flash cards or independent exercise as self-checking number words and numerals provide the answer on the reverse side of the card.

Each How Many? set of large 5" x 5" cards contain 50 two-sided activity cards. Each level is color-coded so you can mix levels in a deck and then easily sort them back.
