Active Algebra

This week in Numeracy we were introduced to algebra which is when numbers are replaced by shapes or letters. Sometimes we are given the values and have to work out the calculation however there are examples where we have to work out the values ourselves. In this lesson we looked at the grid below which used three different shapes. The hardest part was finding the starting point. Once we had done that, we could use the information to solve the rest of the problem. Then came the exciting bit! Miss Coade let us create our own and go out on the playground. Using chalk we drew them and waited for other people in our class to come and solve them. Some were really tricky because the groups had left some of the information out. Here are some pictures of the lesson. Can you work them out?
