Term: 2nd Term

Week 9

Class: Primary 6
Age: 11 years
Duration: 40 minutes of 5 periods
Date:
Subject: Mathematics
Topic: Weight

SPECIFIC OBJECTIVES:
At the end of the lesson, pupils should be able to:

  1. Express the same weight in different units.
  2. Convert from one unit of weight to another.
  3. Add, subtract, multiply, and divide weights.
  4. Solve real-life problems related to weight.
  5. Solve quantitative reasoning questions related to weight.

INSTRUCTIONAL TECHNIQUES:

  • Demonstration
  • Group activities
  • Problem-solving approach
  • Use of teaching aids (weights, balance scales, etc.)
  • Interactive discussions

INSTRUCTIONAL MATERIALS:

  • Balance scales
  • Weights (measuring cups, kitchen scales, etc.)
  • Flashcards with weight conversion examples
  • Markers, whiteboard, and erasers
  • Worksheets for exercises

INSTRUCTIONAL PROCEDURES:

PERIOD 1 and 2:
PRESENTATION

Step

Teacher’s Activity

Pupil’s Activity

STEP 1 - INTRODUCTION

Introduces the concept of weight and different units of measurement (grams, kilograms, milligrams).

Pupils listen and participate in the discussion.

STEP 2 - EXPLANATION

Explains how to convert weight from one unit to another. Example: 1 kilogram = 1000 grams, 1 gram = 1000 milligrams.

Pupils take notes on conversions.

STEP 3 - DEMONSTRATION

Demonstrates converting weight units using real-life examples (e.g., weighing food items).

Pupils follow along and convert weights using examples provided.

STEP 4 - NOTE TAKING

Pupils take notes on the conversion of weights.

Pupils write down conversion facts.

NOTE (On the Board):
Weight Conversion:

  • 1 kilogram = 1000 grams
  • 1 gram = 1000 milligrams
  • Examples:
    • Convert 3 kilograms to grams: 3 kg = 3000 g
    • Convert 500 milligrams to grams: 500 mg = 0.5 g

EVALUATION:

  • Ask pupils to convert various weights from one unit to another.
  • Provide examples for pupils to practice on their own.

CLASSWORK:

  • Convert the following weights:
    • 2.5 kilograms to grams
    • 1500 milligrams to grams
    • 3 kilograms to milligrams

ASSIGNMENT:

  • Convert the weight of different items at home into different units (e.g., convert a 2-kg bag of flour into grams and milligrams).

CONCLUSION:

  • The teacher commends the pupils for their participation and understanding of weight conversion.

 

PERIOD 3 and 4:
PRESENTATION

Step

Teacher’s Activity

Pupil’s Activity

STEP 1 - INTRODUCTION

Introduces addition, subtraction, multiplication, and division of weights.

Pupils engage in a short discussion about the operations.

STEP 2 - EXPLANATION

Explains how to perform addition, subtraction, multiplication, and division with weights (e.g., adding kilograms, subtracting grams).

Pupils listen and take notes on the operations.

STEP 3 - DEMONSTRATION

Demonstrates the operations with real-life examples (e.g., adding the weight of two apples).

Pupils work on examples with teacher guidance.

STEP 4 - NOTE TAKING

Pupils take notes on performing operations with weights.

Pupils take notes on the methods of operations with weights.

NOTE (On the Board):
Operations with Weights:

  • Addition: Add weights in the same unit.
    • Example: 3 kg + 2 kg = 5 kg
  • Subtraction: Subtract weights in the same unit.
    • Example: 5 kg – 3 kg = 2 kg
  • Multiplication: Multiply weights by numbers.
    • Example: 2 kg × 3 = 6 kg
  • Division: Divide weights by numbers.
    • Example: 6 kg ÷ 3 = 2 kg

EVALUATION:

  • Provide exercises for pupils to practice operations with weights.
  • Solve problems involving operations with weights.

CLASSWORK:

  • Perform the following operations:
    • 3 kg + 2 kg
    • 500 g – 200 g
    • 4 kg × 5
    • 8 kg ÷ 4

ASSIGNMENT:

  • Solve 10 weight-related problems that require addition, subtraction, multiplication, and division.

CONCLUSION:

  • The teacher commends the pupils for their hard work and encourages practice.

 

PERIOD 5:
PRESENTATION

Step

Teacher’s Activity

Pupil’s Activity

STEP 1 - INTRODUCTION

Recap the lessons on weight conversion and operations, then focus on real-life applications.

Pupils recall conversion and operations.

STEP 2 - EXPLANATION

Discuss how weight is used in real-life situations (e.g., buying ingredients, measuring luggage).

Pupils listen and participate.

STEP 3 - DEMONSTRATION

Provide real-life examples of problems involving weight.

Pupils work in groups to solve real-life weight problems.

STEP 4 - NOTE TAKING

Pupils take notes on real-life applications of weight.

Pupils write down notes from examples discussed.

EVALUATION:

  • Provide real-life word problems for pupils to solve.
  • Ask pupils to calculate weight in different scenarios.

CLASSWORK:

  • Solve a real-life weight problem (e.g., finding the total weight of items in a shopping basket).

ASSIGNMENT:

  • Find examples of real-life situations where weight conversion or operations are used, and solve them.

CONCLUSION:

  • The teacher commends the pupils and encourages them to continue practicing weight-related problems.

SUMMARY OF LESSON:
This week, the pupils learned how to express weight in different units, convert between units, and perform operations like addition, subtraction, multiplication, and division with weights. They also solved real-life problems involving weight and quantitative reasoning.
