1. Algebra: forming and simplifying expressions, evaluating algebraic expressions, solving equations (including multi-step), nth-term identification, factorising, using indices and substitution. 2. Geometry: transformation types and scale factor, coordinates and midpoint, bearings and angle relationships in parallel lines, interpreting and describing straight-line graphs, properties of isosceles triangles. 3. Number: operations with integers and powers, order of operations (BIDMAS), ratio simplification, working with fractions (including multiplication and division), identifying calculation equivalence. 4. Data handling and statistics: stem-and-leaf diagram completion, comparison of median and range, interpreting frequency data, evaluating data collection methods and correctness of equations. 5. Probability: calculating probability complements, identifying angles as alternate or corresponding, analysing spinner or event probabilities, checking reasoning in solving equations. 6. Scientific applications: solving equations involving powers of 2, 3, and 5, working with approximations and evaluating numerical values involving π in real-world context.
