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.
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 set includes one each of levels 1, 2 and 3, for a total of 150, two-sided activity measuring 5" x 5". Each level is color-coded so you can mix levels in a deck and then easily sort them back.
