Connect number symbols with groups of objects, compare quantities and explore arithmetic through picture-based activities.

Learning levels are starting points, not assessments. These activities supplement learning with a grown-up; they do not promise school readiness or replace a curriculum. Take breaks and choose a level that feels comfortable.
