Mrs. Keaton, our awesome fifth grade math teacher has a special unit she teaches every year during testing. She gives each student a bag of M and M's and has them identify the number of each color and the number of M and M's in each bag. She uses this to teach ratio, percentage, and graphing. Here are some students giving their reflections on the assignment.
If you would like more information about this unit or even like a copy of it send an email or leave a comment and I will be happy to have Mrs. Keaton contact you.
