Numbers & Counting

SequencesLessonsMaterialsVideos
SequencesLessonsMaterialsVideos

One-to-one correspondence, numeral identification, and comparison of quantities using terms like greater than or less than. Establishes the foundation for numerical literacy and early arithmetic operations.

Counting ObjectsOne-to-one correspondence and cardinality skills through counting discrete objects in various arrangements. Strengthens number recognition and the understanding of quantity.
Number NamesIdentification and spelling of number words from zero through millions. Connects numerical symbols to their written linguistic representations to strengthen mathematical literacy.
Comparing NumbersMathematical symbols including greater than (>), less than (<), and equal to (=) to evaluate numerical relationships. Builds fluency in ordering sets and comparing quantities from single digits to multi-digit integers.
