Mix all the numbers up so they are not in order, this helps the child recognize each individual number. Save your pop bottle caps. Write numbers on the top of the pop bottle caps and numbers on a piece of blank paper. You and your child can play a match-up game with the numbers on the pop bottle caps to the numbers on the paper. Have fun while teaching your child their numbers.
