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:
- Read and write large whole numbers.
- Find HCF and LCM of given numbers.
- Solve problems involving fractions and decimals.
- Solve ratio and percentage problems.
- Perform multiplication and division.
- Apply BODMAS correctly.
- 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
