I could totally do this with money-- dollars on a pumpkin then popsicle sticks with bills and coins that add up to the amount. Addition/subtraction sorting - child needs to determine which sticks add up to the number on the bucket.
This is a self-checking "cereal box puzzle" activity that would work well for a math center. If the student has correctly matched the cards, the box front image will be arranged properly when the cards are flipped over. Love this idea!
