An interesting yet easy game to enrich “mental math” subtraction skills is “Penny Hide and Seek.” It uses visual and hands-on practice to help young children quickly and easily remember simple subtraction facts. This aligns with Common Core State Standards, and can be played just about anywhere!
You will need:
Repeat often with different combinations of 5. For example, put four pennies on top and leave one under the plate for 5 - 4 = 1.
Don’t forget to practice the zero fact also. Have your child hide her eyes and put all five pennies on top, so there are zero pennies under the plate for 5 - 5 = 0. Turn the facts around. Put none on top for 5 - 0 = 5.
Once she has easily mastered all the “5” subtraction facts, start the game with six pennies. Keep increasing pennies, by one, until she can easily do all the combinations to 10, and eventually to 20.
This kind of math practice gets your child thinking about numbers in a concrete and versatile way, and puts the “fun” in math fundamentals!
