A4 Simplify and manipulate algebraic expressions (including those involving surds) by: expanding products of two or more binomials factorising quadratic expressions of the form including the difference of two squares factorising quadratic expressions of the form simplifying expressions involving sums, products and powers, including the laws of indices A5 Understand and use standard mathematical formulae Rearrange formulae to change the subject A6 Know the difference between an equation and an identity Argue mathematically to show algebraic expressions are equivalent, and use algebra to support and construct arguments and proofs A7 Where appropriate, interpret simple expressions as functions with inputs and outputs Interpret the reverse process as the inverse function

3 Interpret the succession of two functions as a composite function Topic commentary: Quadratics have been covered in year 10. This is an opportunity to consolidate and extend. This unit covers factorising only. Solving is covered in the next unit although you may choose to teach them together. Functions (A7) is covered in detail in the AQA resources. The PowerPoint slides take students through simple functions, inverse, graphing and composite functions. The notes section suggests which activities from the resource fit in where. The worksheet gives some basic practise with simple functions and includes solving equations, also including composite functions. The Jigsaw activity requires students to evaluate composite functions. NB Students will need to be given the functions required. The dominoes activity requires students to match functions with their inverse to complete a puzzle. Each activity can be used alone or alongside the PowerPoint as a complete lesson.

Topic commentary: This topic builds on students possible prior knowledge of column vectors from their use to represent translations in the transformations topic. Students may confuse column vectors with co-ordinate pairs. They may also initially find the construction of a geometrical proof difficult so a lot of opportunities to consolidate this skill are provided. Throughout the topic, the correct use of notation should be emphasized, such as vectors being expressed in bold font in printed documents and with an arrow of the form. Extension materials are provided which offer additional demand for more able students. Lesson Plans available Notes

22 Topic Title: Equation of a circle 2 lessons Routemap: 3 Year Higher Pre requisite knowledge: Students should know how to calculate the area and perimeter of a circle and be able to use Pythagoras theorem to solve problems. They should also be able to use coordinate geometry to find gradients and equations of straight lines and know that the product of perpendicular lines are -1. Students need to be able to solve both quadratic equations and simultaneous equations where one equation is linear and one is quadratic. It is beneficial if students have some knowledge of circle theorems and rules. Students should be able to: recognise the equation of a circle, centre (0, 0), radius r write down the equation of a circle, centre (0, 0) and radius r work out coordinates of points of intersection of a given circle and a given straight line use the fact that the angle between the tangent and radius is 90 to work out the gradient of a tangent and hence the equation of a tangent at a given point. Number of lessons required: 2 lessons. Higher Content: Recognise and use the equation of a circle with centre at the origin Find the equation of a tangent to a circle at a given point. (A16) Topic commentary: The PowerPoint for this topic demonstrates how the equation of a circle can be derived. There are some simple questions to find the radius from the equation of a circle and vice versa. There is also a revision / introductory activity for relevant circle theorems, leading on to using the fact that gradients of perpendicular lines multiply to -1 to find the equation of a tangent to a circle. The worksheet and homework provide reinforcement of these ideas. The topic requires the candidates to be able to use Pythagoras theorem, circle theorems, and finding equations of lines, but could also be could be used as a revision opportunity for these topics.

25 Topic commentary: Ratio and proportion was covered in Year 10 Students may write a formula with the two variables the wrong way round (finding the inverse of the constant). Encourage students to check their formula by substitution. Students may substitute into the formula, or process incorrectly. Encourage students to write down each step in their working and check their answers. Students may fail to identify the correct type of relationship. Encourage them to read the question carefully, writing down each piece of information as they go. Some students may carry out operations in the wrong order (such as multiplying before squaring). Remind students of BIDMAS. Lesson Plans available Notes AQA Pearsons Lesson Assessment Problem Solving activity

26 Topic Title: Gradients and Rate of Change 4 lessons Routemap: 3 Year Higher Pre requisite knowledge: Students need to be familiar with finding the gradient of a line by using a right-angled triangle and calculating the change in y divided by the change in x. They should also have good basic algebra and geometry skills, including plotting coordinates and selecting axis units. Students should be able to: Higher Content: Interpret the gradient of a straight-line graph as a rate of change (R14) Key words Parallel, perpendicular, gradient, positive, negative, rate of change, instantaneous rate of change, average rate of change, chord, tangent, Number of lessons required: 4 lessons Interpret the gradient at a point on a curve as the instantaneous rate of change (R15) Apply the concepts of average and instantaneous rates of change (gradients of chords and tangents) in numerical, algebraic and graphical contexts (R15) Topic commentary: AQA: There are 6 lessons in this topic. The topic has been approached in a systematic way working from revision of gradients of straight lines to finding and using the gradient of a curve. There are opportunities to bring in some basic pre-calculus ideas with students if desired; indeed, there are overlaps with this topic and the later pre-calculus and area under a curve topic, however it is suggested that this topic is completed first. Not all lessons may be needed and several could stand alone if preferred. Lesson Plans available AQA Pearsons Notes 6 lessons available 6.3 Graphing rates of change 11.2,11.3??
