Subitizing is the ability to instantly recognize a small quantity without counting. Subitizing is a fundamental skill that leads to the ability to compose and decompose number, which is the foundation for fact fluency. Students in Kindergarten and 1st Grade should have daily opportunities to subitize with both structured and unstructured arrangements.
