In K5, children focus on two critical areas: (1) representing, relating, and operating on whole numbers, initially with sets of objects: (2) describing shapes and space. More learning time in Kindergarten is devoted to number than to other topics.

- Use appropriate tools strategically.
- Attend to precision.
- Look for and make use of structure.
- Look for and express regularity in repeated reasoning.
Counting and Cardinality
- Know number names and the count sequence.
