We teach a six week unit in 2nd grade following our Common Core standards. I used this each week to have students write 3-4 sentences on our topic, revise, and then complete their final draft. The final page was used as a spot to put an opinion piece on what they think is the most important thing they can do to stay healthy. You could also use it to discuss other body systems/organs. If you need any additional pages made, please let me know.
