Have your children sharpen their math skills even more. Give each player a piece of paper and a pencil. Using all four cards and a choice of any combination of addition, subtraction, multiplication, and division, have each player see how many different answers a person can get in 5 minutes.
Players get one point for each answer.
Each player alternates drawing one card at a time, trying to create the largest 5 digit number possible. One round goes until each player has 6 cards. At that point, each player chooses one card to throw out to make the largest 5-digit number possible. Each player receives one-half of the cards. Players turn over 2 cards each at the same time.
