Our problem solving challenge today was called Robot Monsters. We had to use a head, a body and legs to make our robot. We had to make the shortest and the tallest we could. The tallest was 21cm and the shortest was 14cm. We learnt we could make different combinations using different parts each time. To find more combinations we kept the heads the same and changed the bodies and legs. Here are our favourite robots. We all chose the same head because it was cute and funny.
