Taste the Rainbow! In order to bring ratio and proportions to life I've used skittles to help my students grasp this concept. When I did this with my class I gave partners a bag of 50 assorted skittles. You may want to change that number for more advanced classes, so that when finding the proportions will be a little more difficult that 50. You can print this packet without the background and students can write on it. My students absolutely loved this and totally master ratio and proportions.
