Then I taught another wonderful lesson from Marilyn Burns... (although the worksheets were self created). I explained to the students that they were going to need to work cooperatively in groups to share paper cookies. We talked about what cooperation looks like and sounds like. I had 4 groups of four students and 1 group of six students.
Once the students solved the problem of sharing a specific number of cookies, they brought me their evidence (the worksheet with cut up cookies shared equally) and I would assign them a new challenge to share a different number of cookies.
In the second block of the lesson we met back together as a class and the students shared their answers. What was wonderful was the connection the students made to equivalent fractions. Through looking at the multiple ways the students divided up the cookies we could see visually and symbolically equivalent fractions!
