# THIRD TERM MATHEMATICS SCHEME OF WORK FOR PRIMARY FOUR (4)﻿

WEEK 1 CONTENTS

• ESTIMATING LENGTHS AND COMPARING MEASUREMENT

LESSON OBJECTIVE: Pupils should be able to:

• estimate distance in kilometer and meters e.g. estimate the width or Heights of:
• the height of tall tree
• height of girl
• Height of door to the nearest half Centimeters. Then measure them.
• Compare measurements in meters and kilo meters. E.g. Olu walks to school which is a quarter of a kilometer from his House. If it takes him 15 minutes to get to school, how many metres does he walk?

1 kelometre (km) = 1000 metre(m)

1/4KM = 100*1/4 metres

= 1000m/4 = 250 metres

LESSON OBJECTIVE: Pupils should be able to:

1. Add length in kilometres and metres. E.g. 7km + 3km + 654 + 24m
2. Subtract length in kilometres and metres e.g 9km – 3km – 374m

QUANTITATIVE REASONING:  Solve quantitative aptitude problems involving lengths.

E = 15km: p = 14km, j = 28km, m =75km. what is

1. E + P
2. M – j
3. (15 + 14) km = 29km
4. (75 – 28)km = 47km

WEEK 2 CONTENT: WEIGHT

1. Addition and Subtraction of Weights
2. Multiplication of Weight in Kilograms by whole numbers
3. Division of weight on Kilograms and Grams by whole Numbers.
4. Word problems on weight.

LESSON OBJECTIVE: Pupils should be able to:

1. Solve problems on weight of objects e.g. 245 + 416g = 661g
2. Solve problems on multiplication of weight in kg and grams b whole numbers. E.g. (a) 428g * 2 (b) 4kg52g* 4
3. Solve problems on division of weight on kg and g by whole number. (a) 428g * 2 (b) 4kg 350g/5.

Weight some object in their classroom environment.

Examples: A table weights 15kg, a box weights 10kg, a book weights 5kg

1. What is the difference between the weight of a table and a book?
2. Which two items weight the same as the third item?

QUANTITATIVE REASONING:  Solve quantitative aptitude problems involving weights.

WEEK 3 CONTENTS: TIME, CALENDER AND DATES

LESSON OBJECTIVE: Pupils should be able to:

1. Identify the seconds, minutes and hour hands on a clock
2. Tell the time on the clock
3. Read the calendar and recite 60 seconds make 1 minutes rhyme table of times.

QUANTITATIVE REASONING:  Solve exercises on quantitative aptitude problems related to time.

E.g. in 24 hours clock

1. 13 hours  = ————- pm
2. 18 hours = —————pm
3. 03 hour = —————- am

WEEK 4 CONTENTS

1. Area of Rectangles Square

LESSON OBJECTIVE: Pupils should be able to:

1. State the properties of a square
2. State the properties of a rectangle
3. Find area of rectangles using the Formula i.e L * B sq unit or L * W sq unit, where: L = Length, B = Breath, W = Wealth. Note: B = W
4. Calculate areas involving square metres and hectares.
5. Develop interest in finding areas of shapes in their Environment.
• QUANTITATIVE REASONING:  Solve problems on quantitative reasoning related to areas.

WEEK 5 CONTENTS

1. Capacity Addition and subtraction in litres

LESSON OBJECTIVE: Pupils should be able to:

1. Recapitulate the standard measurement of some liquid e.g. Bottle of coke, a gallon of Kerosene, table water.
2. Convert litres to centiliters accurately e.g 1000cl = 1L
3. Add in litres correctly. E.g 9.45L + 3.54 L  = 12.99L
4. Subtract in litres correctly. E.g 8.6L – 4.35L
• QUANTITATIVE REASONING:  Solve problems on quantitative reasoning related to capacity.

WEEK 6 CONTENTS

1. Capacity: multiplication and Division in litres

LESSON OBJECTIVE: Pupils should be able to:

1. Multiply in litres by whole Numbers e.g 6.7L * 5 = 33.5L
2. Divide a litres by whole Numbers e.g 3.5L /5 =  0.65L
3. Appreciate litre as the unit of Capacity.
4. QUANTITATIVE REASONING:  Guide pupils to solve problems on quantitative Reasoning.

WEEK 7 CONTENT: PLANE SHAPES e.g. Rectangle Equilateral, isosceles triangle, Rhombus Trapezium, Kite Parallelogram. Etc.

LESSON OBJECTIVE: Pupils should be able to:

1. State meaning of symmetry
2. Identify symmetrical plane shapes e.g. Square etc.
3. Locate line(s) of Symmetry of plane figures at school and Homes.
4. Identify right angle, acute and obtuse angle in plane shapes.
5. Identify north (N), South(s), East (E) and west (W).
6. Distinguish between horizontal and vertical line.

WEEK 8 CONTENTS: THREE (3) DIMENSIONAL SHAPES E.G CUBOIDS, CUBE AND CYLINDERS.

LESSON OBJECTIVE: Pupils should be able to:

1. Distinguish between open and close shapes i.e.
2. Three length to be measured and
3. Two length to be measured in open shapes.
4. State the properties  off each  close shape e.g.
5. Number of edges
6. Number of vertices
7. Number of plan faces
8. Appreciate the presence and use of 3 dimensional shapes in homes i.e. for keeping load or materials like books etc.

WEEK 9 CONTENT: PICTOGRAM AND MODE

LESSON OBJECTIVE: Pupils should be able to:

1. Represent data on a pictogram. E.g beans(4), Groundnut (6)
2. Determine the  mode from the Pictogram(Note : Mode means)

QUANTITATIVE REASONING: solve problems on quantitative Reasoning. Find mode.
