How to Support at Home
Daily Activities
Count everything (stairs, toys, snacks)Play addition/subtraction gamesLook for shapes in the environmentPractice telling time
Weekly Practice
15-20 minutes of worksheet practiceMath games with cards or diceCooking together (measuring)Building with blocks (geometry)
