Cambridge Progression Test Stage 9 Mathematics 2018 Paper 1

1. Algebra: expanding and simplifying expressions, nth-term formula, solving linear and simultaneous equations, standard form and powers, fractional expressions, arithmetic estimation.
2. Geometry: 2D shape naming from projections, prism volume, area and perimeter differences, drawing with bearings and scale, coordinates and table plotting for linear graphs, working with right-angle quadrilaterals.
3. Number: operations with negatives, matching decimal calculations to answers, square roots and powers (e.g. 2⁰, 2⁻³), calculation with mixed numbers, multiplying decimals.
4. Graphs and data: interpreting scatter graphs (correlation, predictions), plotting graphs from tables, evaluating accuracy of real-life values using graph evidence.
5. Ratio and proportion: solving percentage reduction problems, distance scaling (map scale), solving ratio-based cube color probability, interpreting proportional differences in shape dimensions.
6. Probability: calculating remaining and fractional probabilities, identifying gaps in total probability, interpreting probability distributions with other-colored outcomes.
