Parent Tips 🌟
- Use real money (dollar bills) to show subtraction - "If you have $7 and give me $2, how much is left?"
- Play "Subtraction Bowling" - Set up 10 cups, knock some down, and calculate how many remain
- Count backwards from larger numbers during everyday activities (like counting down stairs)
