Math problem Solving

At the start of the term we did a target student group, they were the experts. The experts learnt things so when they go off and do there other group and they could not tell them the answer we told them the questions that we were told in our other group. Not everyone went in the expert group. It was like about five people there in the group. In our expert group we learnt about wingspan. We had to measure our wingspan.. We also did our height. I was 133 cm.
