One side I may put down the unit questions- the other side they write the answers to each wuestion or vise versa- I have created Science/ Social studies fact files where they fill in information through various summarizing/ outlining activities- ie: using these three words summarize this section in 1 sentence. ABC's of Earth- Space-Southwest- whatever unit we are studying. They also take a piece of paper fold it hotdog styke- tear the first layer into however many vocab terms they have for this section. On top tab they write the word inside flap-left definition, inside flap-right a sentence. This way they have all of there studting materials in a file folder to take home for their test. I have other ideas if you are interested.
