PRIMARY 6: MATHEMATICS – SECOND TERM | WEEK 1

TOPIC: REVISION OF FIRST-TERM WORK

A: TEACHING AND LEARNING MATERIALS

  1. Number cards.
  2. Place value chart.
  3. Fraction and percentage charts.
  4. Ratio chart.
  5. BODMAS chart.
  6. Revision exercise sheets.
  7. Pupils’ exercise books and pencils.

B: REFERENCE MATERIALS

  1. Scheme of work.
  2. Recommended Mathematics textbook for Primary 6.
  3. Online educational resources.

C: PREVIOUS KNOWLEDGE

The pupils have learnt whole numbers, binary numbers, place value, HCF, LCM, fractions, decimals, ratio, percentage, multiplication, division and BODMAS during the first term.

D: PERFORMANCE OBJECTIVES

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

  1. Read and write large whole numbers.
  2. Find HCF and LCM of given numbers.
  3. Solve problems involving fractions and decimals.
  4. Solve ratio and percentage problems.
  5. Perform multiplication and division.
  6. Apply BODMAS correctly.
  7. Convert simple binary numbers.

E: CONTENT

Revision of Whole Numbers

Example:

45,600,120

is read as:

Forty-five million, six hundred thousand, one hundred and twenty.

Revision of HCF and LCM

Find the HCF of 12 and 18.
Factors of 12:
1, 2, 3, 4, 6, 12
Factors of 18:
1, 2, 3, 6, 9, 18
HCF = 6
LCM of 4 and 6 = 12

Revision of Fractions

1/2 + 1/4 = 3/4

3/4 − 1/4 = 1/2

Revision of Percentage

Find 25% of 200.
25/100 × 200 = 50

Revision of Ratio

Simplify:

12 : 8

Divide both by 4:

3 : 2

Revision of Binary Numbers

101₂ = 5₁₀

110₂ = 6₁₀

Revision of BODMAS

Solve:

4 + 3 × 5

Multiplication comes first.
3 × 5 = 15
4 + 15 = 19
