The author spent many years teaching at a selective school with the constant challenge of including the most able pupils, whilst at the same time avoiding the danger of excluding the rest of a class. These blackline masters are the result: many of them include fairly routine work, but most have more difficult questions to provide a challenge for the really able. The answer sections provide guidance on these difficult questions.Book A topics covered include:Thinking decimals;Patterns and problem solving in algebra;Further problem solving with algebra;Equations;Cancelling;Indices and standard form;Reading and drawing graphs;Straight line graphs;Number patterns and algebra;Errors and calculations;Graphs;Solving cubics.
