day of school. love this idea! You can put students in groups and have them come up w/ a structure w/ 100 cups. Would be interesting to see what they come up with! *I can't get the song "Red Solo Cup" out of my head after seeing this pin!
A hundreds chart is a classic math tool that can be used to teach tons of math concepts. To play with some number concepts and show my kids just how fun a hundreds chart can be I made them a big, sticky one out of contact paper!
