First, have your student draw a picture of a snowman. You can either have them draw their own, or work on listening comprehension, following directions, and basic concepts by giving your student(s) specific directions to follow.
Next, have your student describe the snowman that he/she drew. (Personally, I love the Expanding Expression Tool, so I incorporated that tool into this activity.) For younger students, you can write down their responses, and for older students, have them write a short paragraph or story about their snowman. Alternatively, you could have a student give directions to yourself or another student (with a barrier between) to see if the other snowman came out like the picture.
What other goals can you think of to target with this activity?
