Recite the number names to 100 by ones and by tens. Starting at a given number, count forward within 100 and backward within 20.


Clarifications


Clarification 1: When counting forward by ones, students are to say the number names in the standard order and understand that each successive number refers to a quantity that is one larger. When counting backward, students are to understand that each succeeding number in the count sequence refers to a quantity that is one less.

Clarification 2: Within this benchmark, the expectation is to recognize and count to 100 by the end of Kindergarten.
