What is 'Pengertian Gambar Model' in Maths?

Understanding 'Pengertian Gambar Model' in Maths

'Pengertian gambar model' translates to 'model drawing' in English. This approach is a visual problem-solving method, often used to break down mathematical word problems into understandable, actionable steps. In the UK, this method is particularly useful for GCSE and A-Level Maths, helping students build logic and reasoning skills.

Why Use Model Drawing?

Model drawing is beneficial because it simplifies complex problems. By visualising relationships and quantities through diagrams, students can better grasp abstract concepts and solve problems step-by-step.

Key Benefits of Model Drawing

• Improved Comprehension: Visualising problems makes them easier to understand.
• Enhanced Problem-Solving Skills: Encourages logical thinking and systematic approaches.
• Exam Success: Helps students tackle challenging questions in GCSE and A-Level exams.

How to Use Model Drawing

Using model drawing involves creating diagrams to represent the problem. Here’s a step-by-step guide:

1. Read the Problem Carefully: Understand what the question is asking.
2. Identify Key Information: Look for quantities, relationships, and conditions.
3. Draw the Model: Represent the problem using a diagram, such as bar models or geometric shapes.
4. Label the Diagram: Add numbers, variables, and other relevant details.
5. Solve the Problem: Use the diagram to work through the solution.

Example: GCSE Maths Word Problem

Sarah has £50 and spends £20 on books. She then splits the remaining amount equally between her two children. How much does each child receive?

Using model drawing:

• Draw a bar representing £50.
• Shade £20 to show the amount spent on books.
• Divide the remaining £30 into two equal parts (£15 each).

Answer: Each child receives £15.

Types of Models in Maths

Various types of models can be used depending on the problem:

Type of Model	Usage
Bar Models	Representing quantities and relationships.
Geometric Models	Solving geometry-related problems.
Flowcharts	Depicting processes or sequences.

Practice Exercises

Try these exercises to improve your model drawing skills:

Exercise 1: Basic Bar Model

Tom has 12 apples. He gives 5 to his friend. How many apples does Tom have left?

• Draw a bar for 12 apples.
• Shade 5 apples for the amount given away.
• Remaining part of the bar shows 7 apples.

Answer: Tom has 7 apples left.

Exercise 2: Ratio Problem

A bag contains red and blue marbles in the ratio 2:3. If there are 20 marbles in total, how many of each colour are there?

• Draw a bar divided into 5 equal parts (representing the ratio).
• Label 2 parts as red and 3 parts as blue.
• Each part represents 4 marbles (20 ÷ 5).

Answer: There are 8 red marbles and 12 blue marbles.

Exam Technique Tips

Here are some tips for using model drawing effectively in exams:

• Time Management: Practise drawing models quickly to save time during exams.
• Double-Check Diagrams: Ensure your model accurately represents the problem.
• Use Labels: Adding labels helps clarify relationships and quantities.
• Practise Past Papers: Solve real GCSE and A-Level questions using model drawing.
