  1. Problem Solving

  2. PROBLEM SOLVING STRATEGIES: Problem Solving Strategies. • Make a list or table. • Draw a picture or diagram. • Act it out. • Look for a pattern. • Simplify. • Work Backwards. • Break it up. • Guess & Check.

  3. Draw a picture or diagram. • Drawing a picture helps you to see the problem. • Draw a picture or diagram helps you to find the solution to the problem. • Look for clues in the problem that you think suggest that you will need to see parts of the problem to find a solution. • How to use the strategy ‘draw a picture or diagram’ to solve problems. • What types of problems we might use this strategy to solve. • Children practising the strategy. • Using the think board to show your thinking.

  4. PROBLEM SOLVING STEPS: The 4 steps : 1. Understand the problem SEE 2. Devise a plan PLAN 3. Carry out the plan DO 4. Look back (reflect) CHECK

  5. Think Board. 2. Devise a plan. 1. Understand the problem. 3. Carry out the plan. 4. Look back (reflect ).

  6. I Do Problem……. Azziza invited six friends to her birthday party. Each person at the party received a cup with five chocolate lollies and two sticks of chewing gum. How many chocolate lollies and how many sticks of chewing gum were given at the party? I Do While I am working through this question, I will think aloud.

  8. 1. Understand the problem. I Do How many chocolate lollies and how many sticks of chewing gum were given at the party? 6 friends plus Azziza at the party. Each got 5 chocolate lollies. Each got 2 sticks of chewing gum.

  9. 2. Devise a Plan. 2. Devise a plan. • Using the information from the problem, I need to choose a strategy that will help me to solve the problem. • Today I will use ‘Draw a Picture or Diagram’ to help me to solve this problem. I Do

  10. 2. Devise a plan. I Do Draw a picture of a cup with 5 chocolate lollies and 2 sticks of chewing gum for each guest.

  11. 3. Carry out the plan. 3. Carry out the plan. · Carrying out the plan is usually easier than devising the plan · Be patient – most problems are not solved quickly nor on the first attempt · If a plan does not work immediately, be persistent · Do not let yourself get discouraged · If one strategy isn’t working, try a different one I Do

  12. 3. Carry out the plan. I Do

  13. 4. Look Back (Revise) 4. Reflect. • Does my answer make sense? Did I answer all of the questions? • Could I have done this problem another way – maybe even an easier way? I Do

  14. 4. Reflect. I Do 35 chocolate lollies and 14 sticks of chewing gum were given at the party.
