Bringing over 400 real-life challenges to players, Wiebe Carlson’s Discount Math Game teaches children math basics during engaging gameplay. Players purchase furniture, clothing and appliances while confronting fractions, decimals and percents. Kids learn how to make correct payments, give correct change, keep financial records of transactions and reconcile accounts with cash on hand. Just like a real business, the goal is 100 percent accuracy. For two to four players.
