I used this activity as a think, pair, share activity after learning about the Muscular System. First I had students think about the important parts of the muscular system or the importance of the system and then I had students pair together to write their ideas on the arms and then combine to make a man. After completing their activity I had students share with the class. Each partner would get an arm and each pair would get the center man piece. On the man would be the words "Muscular System" and on each arms would be their ideas. I hope this can be used in your classroom just like it was used in mine. My kids loved it!
