Today we measured with mini and big marshmallows. They had to guess and check as well as iterate! Big word but they got it!
We had lots of great questions: how big is a mini and big marshmallow in inches? Centimeters? They even found their ruler on their name tag and used it to measure and figure out the answer to the questions above!
With the big marshmallows they had to visualize using only one and come up with a strategy to help them figure out how many marshmallows long it was. We had two really good strategies that worked!
