*(Calculator is allowed unless otherwise stated)*

- Four operations
- division of a whole number / proper fraction by a proper fraction
*without using calculators* - (Denominators of given fractions should not exceed 12, for calculations without using calculators)
- Exclude:
- division of an improper fraction / mixed number by a proper fraction

- solving word problems involving percentage
- Exclude:
- finding percentage profit / loss

- Ratio
- expressing one quantity as a fraction of another, given their ratio, and vice versa
- finding how many times one quantity is as large as another, given their ratio, and vice versa
- expressing one quantity as a fraction of another given the two quantities

- writing speed in different units such as km/h, m/min, m/s and cm/s
- solving up to 3-step word problems involving speed and average speed
- Exclude:
- conversion of units, e.g. km/h to m/min

- Area and circumference of circle
- use of formulae to calculate the area and circumference of a circle circle
- finding the area and perimeter of
- semicircle (half circle)
- quarter circle

- solving word problems involving area and perimeter
- Exclude:
- finding the radius / diameter of a circle given its area or circumference

- Area and perimeter of composite figure
- finding the area and perimeter of a figure made up of some of the following shapes: square, rectangle, triangle, semicircle and quarter circle

- Volume of cube and cuboid
- finding one dimension of a cuboid given its volume and the other dimensions
- finding the length of one edge of a cube given its volume
- finding the height of a cuboid given its volume and base area
- finding the area of a face of a cuboid given its volume and one dimension
- use of the symbols and
- solving word problems involving volume of a cube / cuboid

- Geometrical figures
- finding unknown angles in geometrical figures involving square, rectangle, parallelogram, rhombus, trapezium and triangle

- reading and interpreting pie charts
- solving 1-step problems using information presented in pie charts
- Exclude:
- use of degrees for calculation

- Algebraic expressions in one variable
- representation of an unknown number using a letter
- simple algebraic expressions such as
- y ± 2, 6 ± y
- y + y
- 3y
y 2 3 ± y 5

- interpreting
- 3y as y + y + y or 3 × y

as y ÷ 2 ory 2

× y1 2

as (3 ± y) ÷ 5 or3 ± y 5

× (3 ± y)1 5

- solving word problems involving algebraic expressions
- Exclude:
- evaluation of expressions involving variable in the denominator such as
1 x - simplification of expressions involving

- fractional coefficients

- brackets

- evaluation of expressions involving variable in the denominator such as
