To create your own deck of cards to play a game of Memory, you'll need 30 index cards, colored pencils or markers, crayons, and a set of watercolors and a paintbrush.

Think of a theme for your deck of cards. For example, your cards could follow a theme such as animals, sports, or your favorite foods. Brainstorm a list of 15 different illustrations for the face side of your cards. Then draw each of your illustrations on two separate cards, so that there are two of each type. For an animal-themed deck, you might have two turtle cards, two dog cards, two bird cards, and so on.

To decorate the back side of your cards, think about a simple pattern that connects with the theme of your cards. The pattern should look the same on the back of every card. Lay the cards out on a sheet of old newspaper, face down. Use crayons to draw your pattern on every card, pressing firmly. Then use the watercolor paints to brush a background color over the pattern (the crayon will resist the paint, so you will still be able to see your pattern). Give them time to dry. If your cards buckle (become wavy), press them flat under a heavy book.

To play, lay out all of the cards, face down. Each player takes a turn flipping two cards to face up. If the two match, that player takes the cards and flips two more. If they don't match, the player flips the cards back face down, and then next player takes a turn. When all of the cards have been collected, the player with the most cards wins.
