Wonder Number Learning Games

There are several different versions of Squares. The most basic one is to try to make a square by placing four chips at the four corners of a square. The smallest square is 2x2; such as covering the numbers 45, 46, 55, and 56 (see fig 11). The largest square is 10x10; covering numbers 1, 10, 91, and 100 (see fig 12).

If children confuse squares with rectangles, avoid this confusion by instructing them that all four sides of a square are equal. You can introduce or reinforce this concept visually by building several squares and rectangles on the board and explaining the difference.

When children are first playing the game, it is a good idea to have them say aloud what they have spun – “Blue 2, Red 3, Yellow 4”, etc. This will reinforce what they’re looking for on the board.

Each player selects a different color of chips. The youngest player can go first or each player can take one spin, and the player who spins the highest number goes first.

To begin the game, the first player spins. If the spinner stops on any number from 2 to 10, then a chip may be placed on any multiple of the number spun. If a square, prime, or odd is spun, then any number that fits those definitions is allowed.

Young children not familiar with the terminology of multiples, squares, and primes, can simply match a color or shape on the board to what they have spun.

Each player individually spins, and then places a chip on a block which matches their spin. Only one chip may be placed on each block.

A player may use their turn to block an opponent from building a square. The first player to build any size square on the board is the winner.

A more advanced version of the game is a great way to introduce the concept of area. In this game, play continues after a square is built and the player gets points based on the size of the square. A 2x2 square is worth four points; a 10x10 square is worth 100 points. Players can determine the total number of points simply by counting or multiplying two sides to get the area. The same number can be used as a corner in more than one square. Play continues until all spaces on the board are covered, and the player with the highest score wins (see fig 13). Remember, players must always make squares, not rectangles!
