# THIRD TERM MATHEMATICS SCHEME OF WORK FOR PRIMARY SIX (6)

**WEEK
1 CONTENTS: REVISION OF LAST TERMS WORK**.

**WEEK
2 TOPIC: OPEN SENTENCES**

**Open sentences**

**LESSON
OBJECTIVE**: Pupils should be able to:

- Solve problems express as open sentences
- Interpret words into open sentences and solve them. E.g.
- If 40 notes are to be shared among 5 pupils, how many books will be given to a pupil?

5 pupils ———————-40 notes

1 pupils ———————– (40 / 5) notes

= 8 notes

- Find the letters e.g. 2y+6 = 30

2y = 30 – 6

2y = 24 divide both sides by 2

2y/2 = 24/2

Y = 12

- Solve more problems on simple questions

4x + 2 = 6 + 2x collect like terms

= 4x – 2x = 6 -2 divide both sides by 2

2/2 = 4/2

X = 12

**QUANTITATIVE REASONING:**children should be able to solve related problem on quantitative aptitude.

** WEEK 3 CONTENTS: ANGLES (MEASURING OF ANGLES).**

**LESSON
OBJECTIVE**: Pupils should be able to:

**WEEK
7 CONTENT: EVERYDAY STATISTICS**

**POPULATION**

**LESSON
OBJECTIVE**: Pupils will be able to:

- The meaning of population i.e. population is all people who live in an area e.g. state, country, community etc.
- Interpret pictograms and bar graphs. E.g. using picture of represents data. i.e. 5 people represent.

**Bar
graph:** the use of rectangular bar to represent data

- Collect data and prepare tally of where necessary e.g. (2, 4, 2, 3,3,4,3).
- Use table to prepare bar graphs.

**Note:**
Scale is necessary to draw bar graph i.e. 2cm represent 5 units and so on.

- Calculate data represented on pie-chart.
- Perform some experiments on data collection e.g. tossing of a coin.
- Pupils should be able to find the mode, median and mean of data. (2, 3, 4, 5, 2, 2, 3, 4).

Note;

**MODE**:
the most occurred in data collected or the one with highest frequency (tall
mark)

**MEDIAN:** the
middle i.e. of odd on is gang to be in the middle and the two number divided by
2 will give median number.

**MEAN:** the
total of the data collected, divided by the total frequency i.e. total number
of appearance of all date.

**QUANTITATIVE

statistics.
