Small Collection Namer

Names groups of at least 1, 2, and 3 (or higher) with increasing accuracy. Most children of about 34-39 months of age can accurately name groups of 1, 2, and 3. Many children learn to recognize and name groups of 4 about 6 months later. The child is able to recognize small groups without relying on a model or matching strategy.

Help your student become a(n) Small Collection Namer

Everyday experiences discussing "one," "two," and even "three" objects (or sounds or actions) help children build the basic idea of number.

Practice-based Research: In everyday and small group activitities, playfully assess how high and accurately each child can name the number in small sets; increase the amount for each child to discover what numbers he or she knows.

Using numerals to label numbers, as well as representing collections with written symbols, are key steps toward mathematical abstraction.
