This is a great addition to your 3R unit! The activity has students think about ways to "reuse" certain items listed on the page. They can write a sentence explaining their use and then draw a picture. It's a great way for your students to share their ideas of how they could possible "reuse" items! There are two pages so that you can simply make it front to back.
