Coin Capers
by Michelle and Dave Youngs.

The Puzzle Corner this month has two versions which are variations of a common theme in manipulation puzzles. In each game the goal is to switch the position of two or more sets of coins by moving them within the spaces provided. Coins may only move into adjacent empty spaces. No jumping is allowed, but coins may move in either direction.

In Version One there is a row of 13 squares, with two additional squares above the middle square. In this version, four pennies are placed at the four far-left squares, and four dimes are placed in the four far-right squares. The challenge is to switch the positions of the dimes and the pennies, and to do this in the fewest possible moves.

In Version Two there are two rows of 11 squares connected by a single square in the middle. Version Two has two games, both of which require four types of coins. Quarters go in the upper left corner, nickels go in the lower left corner, dimes go in the upper right corner, and pennies go in the lower right corner. In the first game, the quarters and nickels switch places, and the dimes and pennies switch places. In the second game, the quarters and pennies switch places, and the dimes and nickels switch places. You may decide to use both or only one of these versions with your students.

Other objects may be substituted for coins, however, they must be small enough to fit in the spaces on the student sheets, and be of four different types. Colored buttons, different types of beans, or centicubes would all work equally well.
