- Properties of rational numbersLesson
Add, subtract, multiply and divide rational numbers, and use the properties that make the work shorter.
- Squares and square rootsLesson
Square whole numbers and find the square roots of perfect squares.
- Cubes and cube rootsLesson
Cube a number, recognise a perfect cube, and find a cube root by prime factorisation.
Algebra
- Algebraic identitiesLesson
Use (a + b)², (a - b)² and a² - b² to expand brackets and to multiply quickly.
- Linear equations with the unknown on both sidesLesson
Solve equations that have the unknown on both sides, and use them to answer word problems.
- FactorisationLesson
Break an algebraic expression into factors, and use those factors to divide one expression by another.
- Introduction to graphsLesson
Plot and read points on a grid, read a line graph, and work out values from a simple linear relation.
Ratio, proportion and rates of change
Geometry and measures
- Why constructions workLesson
Explain what each compass step guarantees, and decide when a triangle can be constructed at all.
- MensurationLesson
Find areas of trapeziums and circles, and volumes and surface areas of cuboids and cylinders.
- Understanding quadrilateralsLesson
Work out the angles in a polygon and use the properties of parallelograms, rhombuses, rectangles and squares.
