We have started our fraction unit and last week, we created our own fraction strips using colored paper. We started out with the easier fractions, such as 1/2 and 1/3, then we moved to some tougher ones. Students had to figure out how to fold their strips of paper to create the fractions and make sure their pieces were equal. It really stretched their thinking and this came from a math resource written by Van de Wall. It is great!
