- Practice using zero as placeholder when multiplying by 10, 100, or 1000.
Lesson 5 – Factors
Definition: A factor is a number that divides another number exactly.

- 5 is a factor of 20 because 5 × 4 = 20.
- 7 is a factor of 35 because 7 × 5 = 35.
Common Factors Activity:
- 8 and 12 → Factors of 8 = 1, 2, 4, 8; Factors of 12 = 1, 2, 3, 4, 6, 12 → Common = 1, 2, 4; HCF = 4.
- 14 and 28 → Common factors = 1, 2, 7, 14; HCF = 14.
Chapter 3 – Fractions
- Mixed Number: A combination of a whole number and a fraction (e.g. 2½).
- Improper Fraction: Numerator larger than denominator (e.g. 7/4).
- Conversion: 7/4 = 1¾ and 2¾ = 11/4.

- Measured in degrees (°).
- Types: Acute (<90 obtuse="" right="">90° and <180 li="">
- Use a protractor to measure given angles accurately.
Chapter 8 – Decimals I
- Concepts: Tenths, Hundredths, and Thousandths.
- Example: 0.3 = 3/10, 0.45 = 45/100.
- Identify place value of digits in a decimal number.
Chapter 9 – Decimals II
- Adding Decimals: Line up decimal points before addition.
- Subtracting Decimals: Line up points and borrow if needed.
- Example: 3.25 + 1.4 = 4.65; 5.00 – 2.37 = 2.63.
Practice Worksheets
- Fill in the blanks, true/false, and problem-solving tasks.
- Word problems using multiplication and division.
- Exercises on fractions, angles, and decimals for exam review.
