What you need: Two buttons, almonds, tiddlywinks, etc. for markers. Slips of paper with the following labels: half step, whole step, 3rd, 4th, 5th, 6th, 7th, octave. Leave two slips blank. Make two copies of each slip.
What you do: This is a game for two players. One player places his marker on the lowest “A” on the piano; the other player places his marker on the highest “C”. Place the slips in a basket and mix them up. Take turns drawing slips out of the basket, moving your marker toward the middle with the interval specified on the slip. Make sure you use the key on which your marker is resting as the starting place to count the interval. A blank slip of paper means you can’t move. The first person to get to Middle C wins.
