Bain FamilyThis is our family at the summit of Mt. Ellinor in Olympic National Park. It was a great family adventure. We saw many adults turn around before reaching the summit, but we pressed on and enjoyed the summit with a few mountain goats.

Why is math important for our students?

Foundations for Success: The Final Report of the National Mathematics Advisory Panel (2008)

“The eminence, safety, and well-being of nations have been entwined for centuries with the ability of their people to deal with sophisticated quantitative ideas. Leading societies have commanded mathematical skills that have brought them advantages in medicine and health, in technology and commerce, in navigation and exploration, in defense and finance, and in the ability to understand past failures and to forecast future developments.” (p. xi)

“the process of applying previously acquired knowledge to new and unfamiliar situations”

“problem solving means engaging in a task for which the solution method is not known in advance”

Definitions of problem solvingMeir Ben- Mathematics Advisory PanelHur

Joan M. Kenney

“Problem solving requires analysis, heuristics, and reasoning toward self-defined goals”

a process that involves such actions as modeling, formulating, transforming, manipulating, inferring, and communicating

Features of Problem SolvingTeaching Problem Solving Mathematics Advisory Panel

What words tell a person to multiply? Mathematics Advisory Panel

What words tell a person to subtract?

What words do you notice are particularly troublesome to your students?

“Two flags are similar. One flag is three times as long as the other flag. The length of the smaller flag is 8 in. What is the length of the larger flag?”

An Example of Teaching Key wordsUndermines real problem solving the other flag. The length of the smaller flag is 8 in. What is the length of the larger flag?”

Make problem solving a mechanical process which makes students prone to errors

Understanding the language of mathematics is important.

“Two flags are similar. One flag is three times as long as the other flag. The length of the larger flag is 8 in. What is the length of the smaller flag?”

What does research say?Word Wall the other flag. The length of the smaller flag is 8 in. What is the length of the larger flag?”

Semantic Feature Analysis

Literature Strategies for Math WordsStrategies Instruction the other flag. The length of the smaller flag is 8 in. What is the length of the larger flag?”

One Way the other flag. The length of the smaller flag is 8 in. What is the length of the larger flag?”

Another Way

- Teacher models the strategy.
- Students work on problems using that strategy.

- Teacher models the strategy.
- Students work on problems which may or may not use the modeled strategy.

Types of Strategies the other flag. The length of the smaller flag is 8 in. What is the length of the larger flag?”

- Make a Model or Diagram
- Make a Table or List
- Look for Patterns
- Use an Equation or Formula

- Consider a Simpler Case
- Guess and Check/Test
- Work Backward
- Others?

Using a Formula the other flag. The length of the smaller flag is 8 in. What is the length of the larger flag?”

Make a Model or Diagram

Perimeter of a square : P = 4S.

Using this formula, students could determine the side lengths for each of the squares as 10 inches and 9 inches.

Area of a square: A = S2.

Larger square = 100 in.2

Smaller square = 81 in.2

The difference between the areas of the two squares is found by subtracting the smaller area from the larger area.

Use graph paper to draw one square inside the other.

Count the squares to find the difference.

“One square has a perimeter of 40 inches. A second square has a perimeter of 36 inches. What is the positive difference in the areas of the two squares?”

Teaching strategies improves mathematics problem solving abilities.

Teaching strategies does not improve overall math achievement.

Teachers need to avoid teaching strategies as an algorithm.

What does Research Say?Process by George abilities.PÓlya

Understand the Problem abilities.

Make a Plan

Follow/adjust the Plan

Look Back

The Elements of the ProcessDefine important words. abilities.

Identify necessary and unnecessary information.

Stating what is known and unknown.

Determine if other information is needed.

Decide if calculations need to be made prior to another calculation.

Rephrase the problem.

Consider this: pose a problem situation without a question.

Understanding the ProblemSelect a strategy abilities.

Use what is known to determine how to find a solution

The goal would be that students be able to explain, with reasons, why they think their strategy could work.

Make a PlanStudents carry out the plan they made. abilities.

Students show the work that they do, and they may be asked to write explanations.

Students adjust their plan if they notice something isn’t working or they have determined a better way to solve the problem.

Follow/adjust the PlanVery valuable! abilities.

Check that solution fits problem.

Consider strategy choices and their consequences.

Create related problem(s) that could be solved the same way.

Offer changes to the problem and infer their affect on the solution.

Connect to other problems already studied.

Make generalizations.

Look BackThe Teacher’s role abilities.

Undergeneralizations abilities.

Ex.: 3:4 and ¾ are different things

Ex.: “=“ only means perform operations to find answer

Overgeneralizations

Ex.: Multiplying two numbers makes a bigger number

Ex.: Misapplication of regrouping

Ex.: Finding common denominators when multiplying fractions.

Address MisconceptionsFoster a classroom environment friendly to asking questions. abilities.

Adjust content to meet student needs.

Use a wide variety of activities.

Allow time for exploration.

Organize and represent concepts in different ways.

Pose probing questions to foster meta-cognition.

Model meta-cognition.

Promote dialogue.

The EnvironmentAssessment/Evaluation abilities.

Creates a framework to help students see the importance of explaining why they are doing what they are doing.

Use in groups or individually.

Can be used in portfolios to share with parents at conferences or for student self-reflection of progress.

Problem Solving FormTeacher notes while observing problem solving explaining why they are doing what they are doing.

Listen for evidence the student seeks information to fully understand the problem.

Consider a student’s ability to persevere.

Note use of appropriate strategies.

Listen to student oral explanations for misconceptions or proper conceptual understanding.

Look for algorithmic errors.

Anecdotal RecordsMuch the same as anecdotal records, but this may be scored from viewing written work.

A rubric may be formed using Pólya’s process or specific to the learning goals of the lesson.

Share whatever rubric you use with students and make sure they understand it.

Provide opportunities for self-evaluation.
