The student's chart is three pages, as is the key. It's probably too much work to assign the whole thing. I would assign the first page to everyone and use the second and third pages as reteaching for those who struggle with the first page. There are 30 similes and metaphors total. Pages 4-6 are the answer key.
The columns on the chart are: Chapter, page number, simile or metaphor, quote from the book, item #1, item #2, and common characteristic. Students are give hints such as there's a simile on page 6. They have to find it, jot it down, tell what two things are being compared, and what characteristic they have in common.
