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. This set contains all 3 levels of How Many? Activity Cards.

The Level I deck of cards presents simple dot patterns to practice subitizing number up to 20. Level II provides simple grouped patterns for numbers up to 50. Level III presents symmetrical and predictable dot patterns to conceptually subitize dots up to 100. These card decks are great for small group practice 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.
