Students build a joyful, inclusive math community, establishing their sense of belonging while developing foundational number sense. They practice the counting sequence and begin to build understanding of subitizing, one-to-one correspondence, and cardinality.

Students build number sense within 10 through counting, subitizing, and representing quantities. They compare and order numbers, explore 1 more and 1 less, and use five frames and ten frames to recognize structure and make sense of number relationships.

Students explore measurement and data by describing, sorting, classifying, and comparing familiar objects. They collect, represent, and interpret meaningful classroom data while comparing measurable attributes such as length, height, weight, and capacity.
