## Tang Math Card Games

My family has been enjoying Tang Math card games. I purchased two sets, “Home Kit Jr.” for Kâ2 and “Home Kit Sr.” for grades 3â5. (You can also buy the decks singly, but I think that’s a bad deal.) These are great as math exercises; they are less fun but okay as games.

The basic idea of Kakooma is to look at a grid of five or nine numbers and find two numbers than sum (or multiply) to a third. Numtanga shows numbers or values written in different ways; the idea is to find matching numbers on two different cards.

My favorite game is Expresso. A card shows four numbers. You role a die. Then, using two to four of the numbers (or three or four of the numbers with the harder cards), you figure out a way to add, subtract, multiply, or divide to reach the value on the die. This can get quite challenging.

What we did is just go around in a circle with everyone taking a turn solving an Expresso puzzle. You can also make this competitive my seeing who can find a successful solution first, but generally that would favor the person fastest at finding such patters, so I don’t think that would be much fun.

Here’s another way to make the game harder and more competitive: Take turns, but each player tries to find as many solutions for each card and die roll as possible. Then, the player with the most successful solutions wins the card. In cases of a tie, the person whose turn it is (or who is next in line) wins the tie.

## A Simple Dice Game for Adding and Subtracting

The dice game Yatzee is great for older children to work on sums. But what about younger children? Yahtze is just too complicated for those just starting out with math. I toyed with the idea of modifying Yahtzee for younger children but came up blank. But then I hit upon a simple two-dice game that my five-year-old has enjoyed.
