Teacher feedback: Just finished this activity and my 7th graders loved it. They were so creative finding different ways to make 32 servings. Each student was trying to out-do the other with more complex use of serving amounts and proportions. Lots of fun! - Mrs. Keli Leunes, Math Teacher, PAAAS Plainfield, NJ
