This week we have been looking at shape. On Friday, we looked at symmetry. This is a skill which we often struggle with and struggle to explain our understanding. After discussing how to solve a symmetry problem, we looked at some of our own. We then practised explaining our understanding by convincing. First we had to convince ourselves that we were correct. We used this time to carefully form our sentences and think about what we were saying. Then we convince our partner and finally the group. If we were challenged then our group had to discuss it until we reached an answer.
