PERFORMANCE OBJECTIVES

By the end of the lesson, the pupils should have attained the following objectives (cognitive, affective and psychomotor) and should be able to –

1. measure in metric system the length and breadth of common objects and things;

2. record their measurements in tabular form; and compute the areas of the objects and things.

 

ENTRY BEHAVIOR

Measurement

 

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of –

meter rule, tape rule, desks and tables in the classroom, string, pieces of thread, notebook, and pencil.

 

 

METHOD OF TEACHING – Choose a suitable and appropriate methods for the lessons.

Note – Irrespective of choosing methods of teaching, always introduce an activities that will arouse pupil’s interest or lead them to the lessons.

CONTENT OF THE LESSON

LESSON ONE – INTRODUCTION (MEANING)

Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events.

 

MEASUREMENT

Measurement is a method of determining quantity, capacity, or dimension. Measuring the length and breadth of objects in metric.

Length may be distinguished from height, which is vertical extent, and width or breadth, which are the distance from side to side, measuring across the object at right angles to the length.

For example, it is possible to cut a length of wire shorter than the wire’s width. In science, we always measure in the metric system of units.

100 centimetres (cm) = 1 metre (m)

 

 

DETERMINE AREA (A) OF OBJECTS

Measure the length and breadth (width) of the following in centimetres and record the values in the table to the right.

Find the areas.

We express area in square centimetres (cm2) or square metre (m2).

Area = Length x Breadth

 

LESSON TWO – AREA OF OBJECTS 

Teacher’s/Pupil’s Activities – Measure and Find the areas of the following objectives –

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. Provides pupils with meter rule, tape rule, etc.

Pupil’s Activities – Measure and record the length and breadth of objects in metric units.

3. Guides the pupils to determine the area of plane surface by direct measurement;

Pupil’s Activities – work in group, use string or pieces of thread to trace the area of desk-top place the string on a metre rule and note the length of the thread or string.

4. Guides the pupils to determine the areas of surfaces by computation (i.e. L x B = A cm2), etc.

Determine the area (A) of their desk-top by computation and compare the results.

 

CONCLUSION

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

 

EVALUATION

Pupils to:

1. measure the length and breadth of objects and things;

2. record measurements in metric units;

3. use their measurements to compute the area of objects and things in the classroom.
