kickball, I'd suggest you call the name they gave you on your letter and discuss it with him or her. They know your child and you can say I was thinking of doing this or that and they'll say that's a good idea or it doesn't really show what we're looking for. Or, they might tell you that the new test scores are all they need. Also, do research on Bloom's Taxonomy and select materials that show the advanced thought process at the top of Bloom's. Original thought or analysis as opposed to just reciting facts. HTH.
