When you see a bag of marshmallows, math might not be the first thing that comes to mind, but one bag of mini marshmallows taught my Pre-K class advanced math concepts such as estimation, comparing amounts and parts of a whole. During our Rapunzel unit, we estimated how many marshmallows we could stack into a tower. After recording our estimates we tested them out and wrote the findings. Then, we ate them! While learning the concepts of more and less, we practiced making groups that were larger, smaller and equal to the number I wrote on the board. Then, we ate them! For another activity we each counted out 10 marshmallows onto a napkin divided into two halves. We moved the marshmallows from side to side while I recorded all the equations of ways to make 10. Then, we ate them! Do you see a pattern here? So the next time you see a bag of marshmallows as empty sugar calories, think of all the learning that can be squished in!
