Summer Term

Support (from Y8 teaching programme)
• Solve more complex problems by breaking them into smaller steps or tasks, choosing and using efficient techniques for calculation.
• Identify the necessary information to solve a problem
• Use logical argument to establish the truth of a statement

Core (from Y9 teaching programme)
• Solve increasingly demanding problems and evaluate solutions; explore connections in mathematics across a range of contexts: number, algebra, shape, space and measures, handling data.
• Represent problems and synthesise information in algebraic, geometric or graphical form; move from one form to another to gain a different perspective on the problem.
• Solve substantial problems by breaking them into simpler tasks, using a range of efficient techniques, methods and resources, including ICT ; use trial and improvement where a more efficient method is not obvious; give solutions to problems to an appropriate degree of accuracy .
• Present a concise, reasoned argument, using symbols, diagrams, graphs and related explanatory text
• Suggest extensions to problems, conjecture and generalise; identify exceptional cases or counter-examples, explaining why.

Extension (from Y9 objectives for able pupils)
• Generate fuller solutions to increasingly demanding problems
• Recognise limitations on the accuracy of data and measurements ; give reasons for choice of presentation, explaining selected features and showing insight into the problem's structure.
• Justify generalisations, arguments or solutions; pose extra constraints and investigate whether particular cases can be generalised further.

What do you need to know before you begin? What are ‘the rules'?

Can algebra be used to represent this problem?

What is the first thing you need to do? Why? Justify?

What difference does it make if you round part way through a complex calculation?

Is this always / sometimes / never true?
