As part of their learning on capacity and volume, P6/7 were given the challenge of designing and constructing a container that would hold exactly 200 pieces of popcorn. Each group got a cup containing 10 pieces of popcorn which they used for estimating. They were only allowed to use paper, tape, scissors and a ruler. We had lots of different shapes and sizes but well done to Beth and Joy, who were the only group to make a container that held exactly 200 pieces of popcorn. Some others were very close and everyone got to enjoy the popcorn afterwards!
