Duration: 40 minutes of 5 periods
Date:
Subject: Mathematics
Topic: Measurement – Height and Short Distances

SPECIFIC OBJECTIVES:

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

Use measuring tapes and rulers appropriately.
Compare the height of different pupils and objects.
Convert between units of measurement (cm, m).
Solve real-life problems involving measurement.
Apply measurement knowledge to classroom situations.
Solve quantitative aptitude questions on measurement.

INSTRUCTIONAL TECHNIQUES:

Demonstration
• Group activities
• Practical and interactive learning
• Problem-solving method
• Inquiry-based learning

INSTRUCTIONAL MATERIALS:

Measuring tape
• Rulers
• Chart showing units of measurement
• Markers and whiteboard
• Real objects (desks, pupils, flowering plants)
• Worksheets and notebooks

INSTRUCTIONAL PROCEDURES

PERIOD 1 and 2:

PRESENTATION

Step	Teacher’s Activity	Pupil’s Activity
STEP 1 – INTRODUCTION	Introduces the topic by asking questions: "How tall are you? How far is your seat from the board?"	Pupils attempt to answer and listen to the teacher.
STEP 2 – EXPLANATION	Explains what measurement is and introduces tools used for measuring (ruler, tape).	Pupils observe the tools and ask questions.
STEP 3 - DEMONSTRATION	Demonstrates how to use a measuring tape and ruler to measure height and distances.	Pupils participate by trying out the measurements in pairs.
STEP 4 - NOTE TAKING	Writes key notes on the board. Pupils copy and discuss the tools and their uses.	Pupils take notes and ask questions.

NOTE (On the Board):

Measurement
• Measurement means finding out the length, height, or distance of an object.
• Tools: Ruler (short objects), Tape (longer measurements)
• Units: cm (centimetres), m (metres)
• 100 cm = 1 m

Examples:
• Height of a pupil = 140 cm
• Length of a table = 1.2 m

EVALUATION:

Ask pupils to name tools for measuring.
• Ask pupils to measure each other’s height.

CLASSWORK:

Measure the heights of 3 classmates.
• Record and write the measurements in cm.

ASSIGNMENT:

Measure your height and your sibling’s height at home and compare both.

CONCLUSION:

Teacher commends pupils for their participation and encourages accurate measurement at home.

PERIOD 3 and 4:

PRESENTATION

Step	Teacher’s Activity	Pupil’s Activity
STEP 1 – INTRODUCTION	Recaps previous lessons, introduces comparison of heights and objects.	Pupils respond and participate.
STEP 2 – EXPLANATION	Teaches how to compare measurements (taller, shorter, same height).	Pupils listen and ask questions.
STEP 3 - DEMONSTRATION	Shows comparison using pupils and classroom objects.	Pupils come out in groups and compare objects.
STEP 4 - NOTE TAKING	Pupils take notes on comparison of height and distances.	Pupils write and give examples.

NOTE (On the Board):

Comparing Heights and Lengths
• Tall, taller, tallest
• Short, shorter, shortest
• Example: Tunde (150cm), Kemi (140cm) → Tunde is taller than Kemi.

Conversion
• 100 cm = 1 m
• To convert cm to m → divide by 100
• To convert m to cm → multiply by 100
• Example: 150 cm = 1.5 m; 2.4 m = 240 cm

EVALUATION:

Pupils compare heights of classmates.
• Convert 200 cm to m, 1.8 m to cm.

CLASSWORK:

Measure and compare 3 objects in the class.
• Convert their lengths from cm to m.

ASSIGNMENT:

Find 5 things at home to measure and write their height in both cm and m.

CONCLUSION:

Teacher praises pupils for participation and assigns fun measurement tasks for home.

PERIOD 5:

PRESENTATION

Step	Teacher’s Activity	Pupil’s Activity
STEP 1 – INTRODUCTION	Introduces real-life measurement problems and quantitative aptitude.	Pupils listen and give real-life examples.
STEP 2 – EXPLANATION	Explains how measurement helps in daily life (e.g., tailoring, farming, building).	Pupils ask questions and give their own examples.
STEP 3 - DEMONSTRATION	Solves sample quantitative aptitude questions on the board.	Pupils solve with the teacher.
STEP 4 - NOTE TAKING	Pupils copy steps to solve measurement problems.	Pupils take notes.

NOTE (On the Board):

Sample Questions:

A table is 2.3 m long. What is it in cm?
→ 2.3 × 100 = 230 cm
Bola’s height is 145 cm, Bisi’s height is 1.4 m. Who is taller?
→ 1.4 m = 140 cm → Bola is taller

EVALUATION:

Solve real-life problems based on height/distance.
• Word problem: A carpet is 250 cm long. How many metres is that?

CLASS ACTIVITY:

Pupils in groups solve 5 questions on measurement.

CLASSWORK:

Solve 4 quantitative aptitude questions on height and distance.

ASSIGNMENT:

Write 3 real-life scenarios where measurement is important and show how to solve problems in each.

CONCLUSION:

Teacher concludes by summarizing measurement importance and encourages consistent practice.

SUMMARY OF LESSON:

This week, pupils will explore measurement by learning how to measure height and short distances, compare and convert units, and solve real-life and mathematical problems related to measurement. Hands-on activities and the use of real-life objects will make learning fun and practical.
