Product Description

(K-2) Subitizing is a very important math skill. Just like the importance of being able to calculate estimates, subitizing is something that comes up in the everyday lives of students.

Perceptual Subitizing is the ability to “see” a small amount of objects and know how many there are without counting.

Conceptual Subitizing refers to the ability to see groups of objects, to combine the groups mentally and to know how many objects there are in the group.

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 subititze 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 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.
