Subitizing—recognizing the number of objects in a group without having to count the objects—is a fundamental building block for developing number sense. These simple dot cards help students learn subitizing and understand the crucial concept of making 10.

The reverse side of the cards features the number word and numeral for instant reinforcement. Teachers use the cards with groups, for follow-up practice in centers, or for individualized self-check activity. Each piece measures 4¾” x 7¾”. 38 two-sided cards per pack.
