Subitizing—recognizing the number of objects in a group without having to count—is a fundamental building block for developing number sense. These simple 4.75" x 7.75" dot cards help students learn subitizing and understand the crucial concept of making ten. The reverse side of the cards features the number word and numeral for instant reinforcement. Teachers use the cards with groups, follow-up practice in centers, or for individualized self-check activity. Each set includes 38 two-sided cards.
