The nonfiction picture book 10 Things I Can Do to Help My World by Melanie Walsh (CAndlewick, 2012) uses lots of empty space, along with simple illustrations, to tell how the narrator (assumed to be a child) helps reduce use of lights, water, and paper, as well as unplugging appliances, recycling, and reusing materials.
With large page flaps, the pages also have another small line of text with a sentence explaining why doing so helps the world. For example, when the narrator explains that he turns off the water when he brushes his teeth, the fact says, “Every time you do this, you save 18 glasses of water.”
This an easy and enjoyable read aloud for both the teacher and the student with the the bright pages, a running narration, and facts.
