Here is an easy Pumpkin Math game I've used with my kids! It's perfect for this time of year when we'll be carving pumpkins!
Just use a piece of paper or felt and cut out a pumpkin shape. Add the Addition and Equals signs to one side and the Minus and Equals signs to the other.
Using some pumpkin seeds (or make your own with papers, felt, foam, etc), place a number of seeds on the top and bottom of the math equation.
Your preschooler can count up the pumpkin seeds and use them to solve the problem.
Doing math is always easier for little ones when you have manipulatives to use to help them count!
You can do this with older kids to and do multiplication and division problems!
