Presentation Transcript

  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.

  2. Problem Solving Area and Perimeter • Jim constructed quadrilaterals with an area of 16 cm2. • Which quadrilateral would have the shortest perimeter? • Jim constructed quadrilaterals with an area of 32 cm2. • Which quadrilateral would have the shortest perimeter? • Jim constructed quadrilaterals with an area of 28 cm2. • Which quadrilateral would have the shortest perimeter?

  3. Problem Solving Area and Perimeter • Harry constructed a square garden with an area of 16 m2. • What is the perimeter of the garden? • Harry constructed a square garden with an area of 49 m2. • What is the perimeter of the garden? • Harry constructed a square garden with an area of 25 m2. • What is the perimeter of the garden? Create your own problem! Now solve it! Measurement and Geometry 61

  4. Problem Solving Area and Perimeter • Harry constructed a rectangular garden with an area of 16 m2. • What is the perimeter of the garden? • Harry constructed a rectangular garden with an area of 49 m2. • What is the perimeter of the garden? • Harry constructed a rectangular garden with an area of 25 m2. • What is the perimeter of the garden?
