# Developing problem solving

Questioning is the basis of all learning.

## Introduction

Page Overview:

Good problem solvers have a general procedure (heuristic), a repertoire of strategies, use metacognition and engage in a positive problem solving disposition.

In 1945 George Polya published his classical book: How to Solve It. In it he identifies a heuristic to use to systematically solve problems, which has been been found, by students and educators, as a powerful tool for solving problems. In it he suggests a four step heuristic for solving problems:

1. Understand the problem
2. Make a plan
3. Carry out the plan
4. Look back on your work and ask, How could it be better?

In his book he describes these steps and ideas to expand them and how to proceed if the problem still doesn't seem solvable. How to Solve It summary. Or Book in .pdf

Information on this page builds on his ideas and provides information to help those who want to explore problem solving for them self or as an educator to facilitate learners in their abilities to solve problems. This information is organized around characteristics of what good problem solvers do: use a heuristic (general procedure), have a repertoire of strategies, use metacognition and develop a problem solving disposition. And suggestions and tools to facilitate learners in becoming good problem solvers.

## Heuristic

A heuristic is a series of general steps which are helpful to know when solving problems. When you use a heuristic it helps you think about what you know or have done and what you need to find out or do to solve problems.

Any one who attempts a problem uses some sort of heuristic. A good question to ask is: how detailed should it be?

To seek an answer to this question, let's look at three levels of possible detail.

A simple beginners heuristic has two steps: meet a problem, try a strategy (usually an operation + - * /).

A step up is the four step heuristic, of George Polya.

To make it more comprehensive, one strategy is to add more steps, like the eight step heuristic below.

However, the more steps added, for comprehensiveness, the harder it becomes to remember all the steps. To help us remember, a good strategy is to keep the steps small and chunk ideas with each step. For example: four step heuristic with subcategory chunks.

I usually begin each year giving students a problem to solve. One I really like is the forty square puzzle. Then, after solving it, we would review what they did, to solve it, and make an initial heuristic.

The following three heuristics are examples created by different levels of students.

# Four Step Problem Solving Heuristic

1. Understand the problem
2. Make a plan
3. Try the plan
4. Look at the solution

# Eight Step Problem Solving Heuristic

1. Use a problem solving mind set
2. Understand the problem and state it in my words
3. Identify important information
4. Identify strategies that might solve the problem
5. Can I solve the problem?
6. Try a strategy
7. Check the outcome
8. Can the problem be solved another way?

# Problem Solving Heuristic

1. Understand the problem

• Engage a problem solving mindset
• Communicate the problem in multiple ways

2. Plan

• Review what is known
• Review possible strategies
• Identify a likely plan

3. Try a plan

4. Reflect to verify and improve

• Examine the solution
• Try another strategy
• Examine plans, process, and mindset

The initial heuristic learners create, at the first of the year, doesn't need to be comprehensive. As you solve more problems through out the year, review the process used to solve problems and encourage learners to consider how to make the heuristic easier for them to use and more comprehensive (see below for possible additions to make it a more comprehensive heuristic). Additionally learners might wonder how they could include different strategies used to solve different problems. To keep the heuristic streamlined as a procedure, I encourage learners to make a separate list for strategies, which is discussed next.

# Problem Solving Heuristic

1. Understand the problem

• Engage a problem solving mindset
• Communicate the problem in multiple ways

2. Plan

• Review what is known
• Review possible strategies
• Ask. Can I solve the problem? If not, can anyone solve the problem?
• Identify likely plan

3. Try a plan

• If it works, ask, is there another way to verify the solution?
• If it doesn't work review the plan and maybe select another plan
• Decide how to communicate and share solutions and process

4. Reflect

• Examine the solution
• Try another strategy
• Examine plans, process, and mindset

### Strategies

To solve a problem, a strategy must be used. Young learners often believe selecting an operation to operate on the numbers is the entire process. However, a good educator can help them understand a heuristic and develop a repertoire of strategies beyond this limited vision, which will empower them to be better problem solvers and to solve complex problems.

To help learners develop their repertoire of problem solving strategies, they must have opportunities to engage with a variety of problems and recognize the strategies they use to solve them. Therefore, it is important to provide problems for different strategies, process their use, and have learners create a list of strategies to use with their heuristic. A list of strategies follows and some sample problems are included.

#### Strategies for solving problems with sample problems

1. Use manipulatives to represent objects and actions in the problem.
2. Work it backwards
• Mazes - sample mazes  created by learners
• Passengers on a bus & train problems
• Fruit fly problem
• A king one day decided to send out his knights in search of mathematical wisdom. One day the king ordered some of his Royal Guard to search throughout the kingdom for mathematical wisdom. They did not return. On the second day he sent out four more knights than he had sent out the day before. Each day the king kept sending out four more knights than he had the day before. Twenty - two knights left the castle on the fifth day. How many knights in all did the king send to look for mathematical wisdom?
• Chris was broke on Friday before she received her weekly envelop of spending money. On Friday night she spent \$1.25. On Saturday her brother paid her a \$1 he owed her. How much was in Chris's envelop if she now has \$2.25?
3. Guess and check, trial and error
• Chris and Sue saw some birds and dogs in the park. Chris said, "We saw 18 birds and dogs." Sue said, "Yes, and they had a total of 52 legs." How many birds and dogs did they see?
• Bucket problems
• Magic triangles & magic square perimeter
• Cork & bottle price - guess & check, trial & error, later algebra
4. Use a graphical representation
5. Organize information with writing, pictures, diagrams, maps, webs, outlines, charts, tables, lists, Venn diagrams, and dichotomous keys
6. Use a pattern, model, representation, equation, or function
7. Use equivalent numbers 3/5, 6/10, 60/100, .6, 60%
8. Numerical, letters, size, rotation, shading, shape, position, subtraction, addition, reflection, multiplication, and recursive
9. Solve a simpler problem or Break a problem into two related problems and solve the original problem in two steps: one for each problem.
10. Use smaller numbers
11. Think of a similar problem
12. Look for clue words
13. Make an analogy
14. Process of elimination or process of identification
15. Try a completely different approach
16. Act it out mentally or physically
• Six people entered a tiddlywinks tournament. Each player played each other person one time. How many games were played?
• The Door Bell Rang by Pat Hutchins - a different way to share sharing 12 cookies each time after the door bell rings.
17. Use logical reasoning: matrices, deductive, inductive, truth tables
18. Use algebraic reasoning
19. Brainstorming
20. Use a design process to create real life products or 3-d models.

### Metacognition, reflection, and problem solving dispositions

Metacognition (conscious thinking about ones decisions and how they affect what one is doing and has done) along with a positive disposition will not only help solve the problem at hand, but if learners recognize a purpose in studying their thinking, they will apply what they learn to create a better problem solving process and be better problem solvers.

They will not only have a problem solving process (heuristic), a repertoire of strategies to solve problems, a desire and disposition to find new problems, and develop the self-efficacy to know they are capable and can solve problems successfully.

Let's see how this problem solving can be used by educators.

## Planning & teaching tools (Pedagogical and curriculum tools)

Information, so far, reviewed the major elements of problem solving, how it develops, and how to facilitate better problem solving. The following information explores an educator tools to support problem solving: instructional role in problem solving, suggestions to help learners solve mathematical problems, ideas to select or make problems, ideas to include in curriculum plans, instruction, assessment, and materials to use with learners.

## Teacher's Role in Problem Solving

2. Offer a problem solving heuristic.
3. Teach a variety of problem solving strategies.
4. Allow time for the students to struggle with a problem
5. Choose problems that require time to think through a solution.
6. Provide a variety of problems.
7. Allow students time to practice a heuristic and strategies.
8. Give similar or the same problem in different ways so learners can apply what they learned and see value in their efforts.
9. Ask questions that encourage students to:
• think divergently.
• explain how they are thinking.
• to share strategies.
• think of other ways that the same problem could be asked.
• think of real life problems that are or relate to the problem.
• discover different problems that can be solved with the same strategy
• discover multiple ways to solve the problem.
• reflect or check their solutions.
• reflect and discuss how they imagined a certain strategy might be possible.
• explain why they have confidence in their solutions.
• that really probe their depth of understanding. Don't assume.
10. Provide encouragement and appreciation:
• appreciate different solutions and strategies.
• encourage students to find multiple solutions to a problem.
• encourage students to take time to solve problems.
• compliment students on good problem solving strategies whether they reach a solution or not.
• make sure students know what a compliment or praise specifically relates to about the problem and problem solving.
• encourage students to keep trying and to learn by correcting mistakes.
• let students know that problem solving is difficult and rewarding.
• share and discuss attitudes and dispositions that are conducive to problem solving.
• when learners have the appearance of satisfaction, ask did you enjoy ...
11. Be a role model:
• solve problems yourself.
• make problem solving a top priority.
• let students know that problem solving is an integral part of your curriculum.
• look for and comment on problem solving situations anywhere they occur.
• embed teaching and learning in a problem solving format.
• use sketches, manipulatives, charts, graphs, and any other kinds of representation that can communicate in different ways.
• Use problem solving strategies and vocabulary.

## Suggestions to Help Learners Solve Mathematical Problems

1. Get the learners attention.
2. Establish a rapport with the learners.
3. Establish what the learners are thinking. Look at what they have done. Ask them what they have done. Ask them to show you what they have done. Use a heuristic to step through what has been done. Careful not to jump to any conclusions before you understand where they are in their thinking. Many times they will solve their own problems when you ask questions to find what they are thinking and wait before making suggestions. Give them the opportunity and pleasure to do as much as possible on their own.
4. Focus on the problem and the strategy to solve the problem. If you must focus on the answer then say, What do you think about that answer? Can you tell how your answer makes sense for the problem? That answer doesn't look right. Vs. You got that one wrong.
5. When you are fairly confident you know there is a problem and what it is, refrain from telling them what to do immediately. The long range goal is to enable them to solve their own problems. Therefore, think about how you can ask a question they might ask to help solve the problem on their own. Or model how you would solve the problem by, thinking aloud as you would step through a problem solving heuristic or select a strategy, or initiate a procedure. For example if they do not understand the directions. Say, Let me see. What do the directions say? Then read the directions aloud. Act like you really do not know and are reading them for the first time and model a strategy to understand what the problem is. Maybe to jot down ideas on the board about the problem or use manipulatives or objects to represent ideas and restate it more clearly.
6. If vocabulary isn't known decide how to find out what the words mean.
7. Restate the problem in your own words or act it out with manipulatives or drama.
8. Use the learners' ideas whenever possible. If they have started using a strategy to solve the problem, then stick with that strategy until it works or they suggests it won't work. Avoid saying here try this way, when this way is different than what they are doing. The way you understand, may not be the way they can understand and most likely they will not use your ideas after you leave or after they complete the assignment. If the strategy, the learners have chosen does not work, then suggest a counter example and let them discover the strategy doesn't always work. The learners must decide to try a different strategy before you introduce it.
9. If they reach a dead end, you can stop for the time being and let them chew on it awhile. If you feel hints are necessary, then you might suggest one by beginning with ... Here is something others have tried ... What do you think?
10. Use wait time after you ask a question and after the learners respond. If you ask them to think about a new idea use plenty of wait time. It is not unusual to wait 15 - 30 seconds. You need to look at the learners and see if they are thinking or confused. Do not allow a lot of time for them to be embarrassed. If you are listening to the them and watching their expressions you will know the difference.
11. Don't stop when they have solved the problem. Ask them if they can do another problem. Or, ask if they can think of another type of problem for which they can use the strategy. If they can't make up a problem to give to them. Don't be afraid to give them a problem that will not work.
12. Ask them to describe what strategy they will use to solve future problems.
13. Celebrate the experience.

### Questions to assess learners' mathematical problem solving

1. Do they use a heuristic?
2. Do they come up with their own strategies for solving problems, or do they expect others to tell them what to do?
3. What do their strategies reveal about their mathematical understanding?
4. Do they understand there are different strategies for solving different kinds of problems?
5. Do they articulate their strategies and try to understand other strategies?
6. How do they use materials to model a mathematical situation to find solutions?
7. How do they keep track of and record their work?
8. Is it difficult for them to talk, draw, and write about their work?
9. Do they solve mathematical problems in ways that make sense to them?
10. How do they work with peers cooperatively, participate in whole class discussion, and share ideas, materials, and their creations?
11. Do they learn from the thinking of others?
12. How do they work independently?
13. Do they have confidence in their own thinking?
14. When given choices, what do they choose: a situation similar to a previous one or a different one?
15. Do they stay in one place, occasionally move comfortably, or move around a lot?
16. Do they consider their disposition when attempting to solve problems?
17. Do they keep a record of problem solving strategies?
18. Do they use metacognition when solving problems?

## Characteristics of a Good Mathematical Problem

1. Interesting - as a topic, subject, or includes people or characters that are interesting. It is fascinating enough to create curiosity and develop a need for a solution. It requires some kind of action to solve - physical manipulation, observation, measurement, classification, or arranging a pattern. Something to entice learners to get involved and focus their attention to bring enough information into their working memory for an initial internal representation that has a chance to lead to a successful solution.

2. Time - the amount of time required to solve the problem is appropriate for the learner's developmental level.

3. Developmentally appropriate - The problem can be solved in a way that will not contradict the learner's developmental way of understanding, if the learner isn't ready for a developmental change.

4. Understandable - Has at least one solution that can be understood by the learner. A solution which is understandable with the mental structures available to the learners so they can organize the information and operate on it in a manner necessary to solve the problem.

5. Emotional value - The problem has characteristics that make it reasonable to assume learners have sufficient self-efficacy and self-confidence to attempt the problem and persist long enough to solve it so they will grow to appreciate and value mathematics in their lives.

6. Communication - The problem provides students with a need or desire to communicate multiple ideas and in multiple ways.

7. Mathematical value - The problem requires mathematical ideas that are powerful and something the learners should know at this point in their lives, will be able to apply it to their world to connect to other mathematical content and process knowledge to increase their feelings of empowerment by knowing.

## Planning questions to prepare to facilitate problem solving & investigating

Imagine doing the investigation and answer these questions:

 Questions to think about how to make it more approachable: How can the problem or investigation be done? What needs to be known to successfully complete it? Is the information needed to successfully complete the problem or investigation either known by the student or available for the student within the problem or investigation. What ways could students visualize the problem or investigation? (pre operationally or concretely.) What materials are needed? Would using different materials make it better? What are the steps for different solutions? What can be written down or recorded? Questions to think about to make it more purposeful: What ideas will the problem or investigation develop? What different concepts, generalizations, big ideas, benchmarks, and landmarks will used or constructed? Is there connections to other mathematical ideas: problem solving heuristic, representations, problem solving strategies, proof and reasoning, communication, connections, habits of the mind, dispositions, attitudes)? How will it create a desire for students to want to communicate mathematically? how will students be able to extend these ideas? how will doing the problem or investigation increase the opportunities for students to interact as a community with mathematical interests. Questions to think about so it will accomplish the purpose for doing it. Can the problem or investigation promote the required reflective thought for students to construct understanding? Is it possible to do the problem or investigation without much reflective thought? IF so, can the problem or investigation be modified so that students will be required to think? What must students reflect on to do the problem or investigation? What ideas must students use to complete the problem or investigation? Questions to think about to make it more teacher friendly. What materials and information might it be necessary to focus student's attention for them to successfully complete the problem or investigation? What directions need to be given? How directive do you want to be? Will directions be oral? Written? Demonstrated? How should students be grouped?
