This alphabet game will get you up and moving. Think of actions or movements that start with each letter of the alphabet.
Try imitating an airplane, bouncing a ball, crawling, dancing, eating, fishing, golfing, hiding, ice skating, jumping, kite flying, laughing, mowing the lawn, nodding, orbiting, painting, quilting, running, sitting, talking on the telephone, playing the ukulele, vacuuming, washing dishes, taking an X-ray, yawning, or zipping.
These ideas will get you started, but there are many more possibilities.
Have a friend guess while you do one letter; your friend can do the next letter.
Or pretend to be a different animal for each letter of the alphabet, such as an aardvark, a bear, cat, dog, and so on.
