**Teaching About Problem Solving**

Welcome to Module 3 Teaching About Problem Solving

2
**Getting Started ? Module 3 continues the focus on problem solving.**

Module 2 covered the importance of problem solving and teaching through problem solving. Module 3 deals with teaching about problem solving ?

3
Getting Started “Becoming a better problem solver is a gradual building process that requires taking on challenging and sometimes frustrating problems.” - Baroody, Fostering Children’s Mathematical Power, Erlbaum, 1998, p. 2-11

4
Key Messages Teaching about problem solving focuses on having students explore and develop problem-solving strategies and processes.

5
Key Messages When students are taught about problem solving, they learn to identify different kinds of problems, problem-solving strategies, and processes. T chart

6
Key Messages Teaching about problem solving will help students develop a mental model for approaching and persisting with a problem-solving task.

7
Key Messages The primary goal of problem solving is making sense of mathematics rather than mastering the steps of a problem-solving model or a set of problem-solving strategies. Snowflakes have many lines of symmetry! I know this because when I make them, I cut on folds through the centre.

8
Key Messages Teachers become role models for problem solving by being flexible, modeling a variety of strategies, and encouraging students to use strategies that make sense to them.

9
Key Messages Since attitudes and beliefs about problem solving have a major impact on student learning, the most important influence that a teacher can have on students is to help them develop attitudes and beliefs that confirm their capability as good problem solvers.

**The Four-Step Problem-Solving Model**

Working on It The Four-Step Problem-Solving Model Understand the problem Make a plan Carry out the plan Look back and reflect on the solution

11
**The Four-Step Problem-Solving Model**

How am I thinking about this? As you solve the following problem, think about the processes that help you at each step of the problem-solving model.

12
**The Four-Step Problem-Solving Model**

Your teacher is organizing a barbeque. Picnic tables need to be ordered so that people will have a place to sit while they are eating. Each picnic table will seat 6 people. Your teacher has sent out invitations that ask for a reply stating the number of people attending from each family. All the replies have been returned and 99 people are planning to attend. How many picnic tables does your teacher need to order? Record your solution on BLM 3.1.

13
**The Four-Step Problem-Solving Model**

Reflect on the processes (actions, thinking strategies, communication) that helped you at each step of the problem-solving model. Record your thoughts on BLM 3.2.

14
**The Four-Step Problem-Solving Model**

Read “The Four-Step Problem-Solving Model” (pp ). Understand the problem Make a plan Carry out the plan Look back and reflect on the solution

15
**The Four-Step Problem-Solving Model**

“Polya’s model can also be misleading if taken at face value. Except for simple problems, it is rarely possible to take the steps in sequence. Students who believe they can proceed one step at a time may find themselves as confused as if they had no model.” - Reys, Lindquist, Lambdid, Smith, & Suydam, Helping Children Learn Mathematics, Wiley, 2001, p. 95

16
**The Four-Step Problem-Solving Model**

Share... your thoughts about the model with the large group.

17
**Problem-Solving Strategies**

Working on It Problem-Solving Strategies

18
**Problem-Solving Strategies**

“Strategies are not learned at a specific time or in a single lesson. Children will use them when they are ready. We structure situations that promote their use, but realize that the child has to decide to use them.” - Trafton & Theissen, Learning Through Problems, Heineman, 1999, p. 44

19
**Problem-Solving Strategies**

Two statements in the guide reflect current practice in teaching students strategies for solving problems.

20
**Problem-Solving Strategies**

Statement One: Problem-solving strategies are best explored by primary students incidentally — within the context of solving daily problems — rather than through direct instruction about the problems themselves.

21
**Problem-Solving Strategies**

Statement Two: Students are often taught to use key words as a strategy for solving word problems. A better strategy would be to have students discuss the known information, the unknown information, and the asked-for information.

22
**Problem-Solving Strategies**

In small groups, discuss ways in which teachers can help students develop problem-solving strategies. (Refer to pp – 5.34 in the guide.) Record your thoughts on chart paper.

23
**Problem-Solving Strategies**

Share... your thoughts with the large group.

24
**The Teacher’s Role in Teaching About Problem Solving**

“Helping students become good problem solvers is like helping them learn how to ride a bicycle; tips can be helpful, but it’s impossible to master the process without actually trying it.” - Baroody, Fostering Children’s Mathematical Power, Erlbaum, 1998, p. 2-11

25
**The Teacher’s Role in Teaching About Problem Solving**

Use a JIGSAW strategy to explore the teacher’s role.

26
**The Teacher’s Role in Teaching About Problem Solving**

Form home groups of six. Pair yourselves. Each pair chooses a different topic, and joins pairs from other groups to study the topic. Let’s find the expert group that’s studying our topic!

27
**The Teacher’s Role in Teaching About Problem Solving**

Expert Group 1 Helping to Develop Strategies (pp – 5.34) Expert Group 2 Choosing Problems (pp – 5.35) Expert Group 3 Problem Posing (pp – 5.36)

28
**The Teacher’s Role in Teaching About Problem Solving**

Share... your expertise when you return to your home group.
