##### KS3 Curriculum Guide - Year 9 Maths
Term 1Percentages, Comparing Statistical Distributions, Formulae & Polygons
Students will learn to calculate simple interest, percentage increases and decreases, reverse percentages, repeated percentage change and compound interest. Students will use grouped frequency tables and construct frequency polygons. They will calculate statistics from given data and use this information to compare distributions. Students will learn to recognise misleading graphs. Students will collect, present and interpret data in order to test an hypothesis. Students will explore the properties of polygons, find internal and external angles of regular polygons and learn why some polygons tessellate and some do not.

Term 2Using Data, Applications of Graphs & Pythagoras
Students will learn about scatter graphs and correlation. Draw and interpret cumulative frequency diagrams and estimate the mean from grouped data. They will use two-way tables to solve problems. Students will learn about step graphs, time graphs and exponential growth. Students will discover Pythagoras’ Theorem and use it to find missing sides in a right-angled triangle. They will use Pythagoras’ Theorem to solve problems.
