I'm sure you have done this activity before, but I thought I would post it for anyone who hasn't, or just as a reminder. Usually I use white marshmallows, and sometimes the big ones, but this time I decided to try these fruity flavored marshmallows. It was a good decision. It added fruity fun to this activity.
We have been working on plane and solid shapes, so my class was already familiar with them before doing this activity. While the 3D solid shapes that can actually be made is very limited, it is still a good activity for students to discover this fact. It is also a good way for them to look at and think about the attributes of the shapes they could make.
I bought 4 bags of marshmallows and 4 boxes of toothpicks for a class size of 26. This was plenty, and I even had some left over. I pre-baggied the marshmallows for students to use. This was helpful, but not necessary. This activity was actually one of my math inquiry activities, so I only had one group doing this at a time. Students anticipated the day it would be their turn. One thing I did to help with this was on the first day I gave all students a few marshmallows to eat.
At the end of the activity I had students bag up their toothpicks, marshmallows and paper towel piece. I had them take everything home, so that they could discuss this activity with their parents. They really enjoyed this activity and I enjoyed watching them being creative.
