These monster math flash cards were created to be used with a punch-a-cup fall festival or Halloween themed game. They can also be used for practice of addition and subtraction facts to 20.
To use as a punch-a-cup game, you will also need to create a punch-a-cup board that goes to 20 twice. This allows students to practice addition and subtraction. When used in a classroom of 20, each student would go twice. When used in homeschool, you could utilize the game board throughout the week, doing 2 addition and 2 subtraction facts daily with one child.
