14 April 2012

Endeavour Primary School

Mathematics Department 2012


Workshop outline

Workshop Outline

  • Introduction to Problem-Solving

  • Model Method

  • 3 Different types of Models

  • 4 different Heuristics

  • Format of assessment


Problem solving approach

Problem-solving Approach

  • Understand the Problem (Understand)

  • Devise a Plan (Plan)

  • Carry out the Plan (Do)

  • Review and discuss the solution (Check)


Problem solving approach1

Problem-solving Approach

  • Understand the Problem (Understand)

    • Read to understand.

    • If at first not clear, read again.

    • Still don’t get it? Read chunk by chunk.

    • Explain the question in another way.

    • Use visualisation tool – model, timeline, diagrams, table etc.


Problem solving approach2

Problem-solving Approach

  • Devise a Plan (Plan)

    • Have I seen a similar or related question before?

    • Do I have a ready plan?

    • Do I have all the data? What data is missing?

    • Can I find the missing data?

    • Can I use a smaller number to try first?

    • Use a heuristics?


Problem solving approach3

Problem-solving Approach

  • Carry out the Plan (Do)

    • Are all my steps accurate?

    • Are there traps I need to be alert of?

    • Have I used all the data given?

    • Do my steps make sense?


Problem solving approach4

Problem-solving Approach

  • Review and discuss the solution (Check)

    • Does the answer make sense?

    • Did I answer the question?

    • Could this problem be solved in a simpler way?


Model method

Model Method

Draw a diagram


Why model drawing

Why Model Drawing?

  • Visual representation of details

    • Majority of our children are visual learners

  • Helps children plan the solution steps for solving the problem

    • Useful in fractions, ratio & percentage


Why model drawing1

WhyModel Drawing?

  • Teaches mathematical language

  • Provides foundation for algebraic understanding

  • Empowers students to think systematically and master more challenging problems


Model drawing does not

Model Drawing does NOT

  • Work in every problem

  • Specify ONE RIGHT model

  • Specify ONE RIGHT operation

At a park, there are 25 bicycles and tricycles. These vehicles have a total of 55 wheels. If there are more bicycles than tricycle, how many bicycles are there at the park?

Method 1: Guess and Check

Method 2: Supposition

Suppose all the vehicles are bicycles, the number of wheels

But there are 55 wheels altogether.

55 ‒ 50 = 5 extra wheels

Each tricycle has 1 wheel more than a bicycle, 5 ÷ 1 = 5

There are 5 tricycles.

25 ‒ 5 = 20

2 x 25 = 50

There are 20 bicycles at the park.
