The intention of this unit is build on and increase the level of rigour in students' mathematical understanding from Key Stage 3, whilst introducing new Key Stage 4 concepts.

• Students develop a flexible understanding of percentage multipliers to solve a range of abstract and financial problems

• Students extend their understanding of transformations to include negative scale factors, invariant points and transformations of graphs.

• Students extend their algebraic manipulation to algebraic fractions and their equation solving to simultaneous equations.

• Students extend their trigonometric reasoning and problem solving to non-right-angled triangles.

• Students extend their ratio and proportional reasoning to formulae for direct and inverse proportion

• Students extend their angle reasoning to proving congruency and appreciate the links with trigonometry.

• Students extend their reasoning with rounding to upper and lower bound calculations

To develop students as independent learners this unit of work covers three terms with a period of revision before a substantial assessment in term 3. This require students to take ownership of their mathematical understanding and engage in a process of identifying gaps and improving ahead of the tests.

From the 3rd week of the unit students will complete a weekly knowledge check so they can measure how their knowledge and expertise is building. The content of the knowledge checks updates as more concepts are covered, to provide a rolling check of what students can recall.

During this unit there will also be several longer written homework tasks which include a knowledge check as well as problem solving questions. Students will have an opportunity to follow-up and improve their work on these homework tasks.

The impact of this unit of work will be measured through a Three 45 minute written assessments in term 3

The assessment will cover every aspect of the unit of work and using the knowledge organiser together with this website is a great way to prepare for the tests.

A shorter mid-term assessment in term 1 provides students with a indication of their progress with the unit. Students can use their feedback from the min-term to prepare for the assessments at the end of the unit.
