# Reverse Percentages

Using equivalent ratios students learn how to work a percentage change in reverse to calculate the original 100% value.  As learning progresses they are challegned to apply their learning to solve real life problems in context.
##### Differentiated Learning Objectives
• All students should be able to calculate 100% when given a representative percentage change.
• Most students should be able to calculate the original value after a real life percentage change.
• Some students should be able to calculate the original value after a compound percentage change.

#### Equation of Straight Line Graphs

To find the equation of straight line graphs students need to calculate the gradient using two pairs of coordinates and the intercept which is the y value of where it crosses the vertical axis.  Examiner’s reports of past exam questions show students are more able to find the intercept of a straight line than they […]

#### Arithmetic and Geometric Sequences

Students learn how to generate and describe arithmetic and geometric sequences on a  position-to-term basis.  Learning progresses from plotting and reading coordinates in the first quadrant to describing geometric sequences using the nth term. This unit takes place in Term 4 of Year 10 and is followed by the equations of straight line graphs. Arithmetic […]
