Term: 1^st Term

Week 8

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

SPECIFIC OBJECTIVES:

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

Define scale drawing.
Draw plane shapes using a given scale.
Convert real-life lengths and distances using a scale.
Interpret and solve real-life problems on scale drawing.
Solve quantitative reasoning questions related to scale drawing.

INSTRUCTIONAL TECHNIQUES:

Demonstration
Hands-on drawing activities
Group tasks
Interactive discussion
Use of measuring tools

INSTRUCTIONAL MATERIALS:

Ruler, pencil, eraser
Graph paper
Sample scale maps
Chart explaining scale drawing
Worksheets with practice tasks

INSTRUCTIONAL PROCEDURES:

PERIOD 1 and 2:

PRESENTATION

Step	Teacher’s Activity	Pupil’s Activity
STEP 1 – INTRODUCTION	Introduces the concept of scale drawing and its uses.	Pupils listen and participate.
STEP 2 – EXPLANATION	Explains how scale drawing represents real objects or distances in smaller measurements.	Pupils ask questions and take notes.
STEP 3 - DEMONSTRATION	Demonstrates drawing a square using a scale of 1 cm : 1 m.	Pupils observe and try the same.
STEP 4 - NOTE TAKING	Pupils write notes and examples of scale drawing.	Pupils practice on graph paper.

NOTE (On the Board):
Scale Drawing:

A scale drawing represents an object with accurate measurements but reduced in size.
Example: A house of 10m length drawn as 10cm using a scale of 1cm:1m.
Common scales: 1cm : 1m, 1cm : 10km, etc.

Exercise:

Draw a rectangle of 3m by 2m using 1cm:1m scale.

EVALUATION:

Ask pupils to explain what scale drawing means and draw a given shape.

CLASSWORK:

Draw a triangle and a square using a given scale.

ASSIGNMENT:

Find 2 objects at home and represent them using scale drawing on paper.

PERIOD 3 and 4:

PRESENTATION

Step	Teacher’s Activity	Pupil’s Activity
STEP 1 – INTRODUCTION	Recap scale drawing definition.	Pupils respond to questions.
STEP 2 - REAL-LIFE APPLICATION	Discusses converting real-life objects (like tables, books) to scaled drawings.	Pupils listen and give examples.
STEP 3 - GROUP WORK	Each group picks an item and creates its scaled drawing.	Pupils draw and measure.
STEP 4 – DISCUSSION	Pupils explain what they did and present their drawing.	Groups share their process and results.

EVALUATION:

Pupils explain how to apply scale drawing in real-life.

CLASSWORK:

Convert 3 real-life items into scaled drawings.

ASSIGNMENT:

Create a mini-room plan using 1cm:1m scale.

PERIOD 5:

PRESENTATION

Step	Teacher’s Activity	Pupil’s Activity
STEP 1 – INTRODUCTION	Introduces scale drawing in Quantitative Reasoning.	Pupils participate in solving QR problems.
STEP 2 - PRACTICE	Guides pupils through QR scale-related questions.	Pupils practice and discuss answers.
STEP 3 - REVIEW	Reviews difficult questions and corrects mistakes.	Pupils listen and correct errors.

CLASSWORK:

Solve 5 QR questions related to scale drawing.

ASSIGNMENT:

Complete QR worksheet on scale drawing at home.

CONCLUSION:
The teacher praises the pupils and encourages them to observe how scale is used in maps, architecture, and design.

SUMMARY OF LESSON:
This week, pupils learned how to use scale drawing to represent real-life objects, convert measurements using scale, and solve related quantitative reasoning problems. They practiced drawing shapes and applying their knowledge in hands-on activities.
