CONTENT OF THE LESSON  

LESSON ONE – INTRODUCTION TO SPEED

Pupil’s Activities 1 – Compare Speed of Two or More Motors

If you are traveling to your hometown, which of the means of land transportation will you like to take? State reasons for any of the list below.

1. Hummer bus

2. Coastal bus

3. Lt bus

4. Volkswagen bus

5. Marcopolo bus

6. Train

 

Expected Pupil’s Response – Money, speed and time.

 

Teacher’s remark – The choice of means of transportation especially land transportation is greatly determined by speed and time takes to reach various destinations. 

 

Teacher’s/Pupil’s Activities 2 – Speed and Time Taken 

Speed is often measured in kilometres per hour (minute) or meters per second. This is written for short as km/h(m) or m/s. To find the average speed, you divide distance covered by time taken.

That is: Average speed =

Distance covered

= _______________________

Time Taken

 

Working Examples

  1. A car takes 3 700 km in 5 hours. What is its average speed?

Given,

Distance = 3 700 km

Time = 5 hours

Average speed

Distance covered

= _______________________

Time Taken

Average speed = 3 700 km /5 h

= 740 km/h

 

  1. Ayomide walked a distance of 180 metres in 5 seconds. Find his average speed.

Average speed = 180 m/5 s = 36 m/s.

 

 

Pupil’s Activities 2 – Class Exercise/Take Home 

 1. If it takes 3 hours to drive a distance of 210 km on a motorway, what would be your average speed in km/h?

2. A train travelled 10 080 km in 12 hours. Find its average speed.

 

LESSON TWO – WORK IN PROGRESS

 

 

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;

2. Guides pupils to calculate average speed as distance covered over time.

Pupil’s Activities – Calculate average speed using distance covered over time.

3. Guides pupils to solve quantitative aptitude problems related to time and speed.

Pupil’s Activities – Solve quantitative aptitude problems related to time and speed.

 

CONCLUSION

To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

 

LESSON EVALUATION 

Pupils to calculate speed when time and distance are given.
