This is a fun warm up that the students do in small groups. All the groups have the key (alphabet and activity for that letter) and then I make up cards with muscles and bones on it. They come up and draw out a card and must use their key to spell out the word. Then they must tell me where that bone or muscle is if they can. You may want to pull out specific muscles that you then may work on that day for stretching or strengthening. To make more cards I simply type out the muscle or bones you may want and tape over the cards that are here as an example, then run off copies.
