Use crayons, toothpicks, construction sticks or 'dead' match-sticks to build and help you solve these problems. You will need to rebuild the set of squares to complete each of the problem next to them.

crayons.

Matchstick pattern 1. By moving only two sticks, make seven squares.

This time move four sticks to create three squares.

Matchstick pattern 2. Change these five squares into four by moving just three sticks.
Matchstick pattern 3. This time, remove six sticks to create two squares.
(Each of the sticks that remain must be part of a square.)

How about removing two sticks so that you can still have six squares remaining!
