Sort it: gives light or not?
Show pictures of the sun, a flashlight, the moon, a lamp, a pencil and a firefly. Kids sort them into "gives light" and "doesn't give light" and explain their thinking. The moon always sparks a great debate, since it only reflects the sun's light.
Why it works: going from real objects to pictures to symbols is a core recommendation of the U.S. Department of Education's elementary math guide.
