R10 solve problems involving direct and inverse proportion, including graphical and algebraic representations 18. R11 use compound units such as speed, rates of pay, unit pricing, density and pressure 19. R13 understand that X is inversely proportional to Y is equivalent to X is proportional to 1/Y; construct and interpret equations that describe direct and inverse proportion 20. R14 … recognise and interpret graphs that illustrate direct and inverse proportion 21. R16 set up, solve and interpret the

answers in growth and decay problems, including compound interest. R6 express a multiplicative relationship between two quantities as a ratio or a fraction • R12 compare lengths, areas and volumes using ratio notation; make links to similarity (including trigonometric ratios) and scale factors • G5 use the basic congruence criteria for triangles (SSS, SAS, ASA, RHS) G6 apply angle facts, triangle congruence, similarity and properties of quadrilaterals to conjecture and derive results about angles and sides, including … the fact that the base angles of an isosceles triangle are equal, and use known results to obtain simple proofs • G7 identify, describe and construct congruent and similar shapes, including on coordinate axes, by considering rotation, reflection, translation and enlargement (including fractional and negative scale factors) • G17 … calculate: surface area and volume of spheres, pyramids, cones and composite solids • G19 apply the concepts of congruence and similarity, including the relationships between lengths, areas and volumes in similar figures

2. Unit proportion
Lesson plan
Recognise and use direct proportion.
Are these pairs of quantities in direct proportion?
a. 10 bread rolls cost £1.60, 15 rolls cost £2.24
Play snap with ratios. Ask students to write three different ratios in their books and stand up. Call out a ratio. If the student has that ratio (or an equivalent ratio) in their book, they can sit down. Do not always call out a ratio in its simplest form. With the final few students, ask them to simplify or find an equivalent ratio to a given example before sitting down. Alternative starter
