1 Implementation Review the mathematical concept. Review the problem solving steps. READ: Children read the part that is asking them to find something out. UNDERSTAND: Children explain what they need to find out. Children identify what information they will need to find it out. Remove the coloured rectangle. Children find the information they need to find it out. CHOOSE A STRATEGY: Children identify strategies that they could use to find it out. USE A STRATEGY: Children use a strategy to find it out. Children record their thinking as they find it out. CHECK: Children reread the part that asked them to find something out. Children check that they have found it out. Children check they have recorded their solution correctly. Children follow the problem solving steps to solve the 2nd level of the problem, with minimal teacher guidance. Children who solve the 2nd level, follow the problem solving steps to solve the 3rd level of the problem independently. Children use the problems as a guide to create their own problem, either alone or in pairs/small groups. Children solve their own problem. Throughout the lesson, children share solution strategies. At the end of the lesson, children explain how they created their own problems.
