Using Graphs to Solve Linear Equations

Students learn about using graphs to solve linear equations. Learning progresses from solving equations where the unknown appears on one side to using the intersection of two graphs to solve equations of the form 2x + 1 = x.

The start of the lesson recaps generating tables of results from an equation.  The plenary challenges students to solve an equation where the unknown appears of both sides.

Differentiated Learning Objectives
  • All students should be able to use graphical methods to estimate a solution to an equation.
  • Most students should be able to use linear graphs to estimate values of y for given values of x and vice versa.
  • Some students should be able to use graphical methods to solve an equation in the form x = mx + c

Teaching Mathematics for a Growth Mindset

Inspiring students to enjoy maths and feel the success that comes with attempting a difficult challenge is why I teach.  The feeling of success is addictive.  The more students experience it the more they want it and the further out of their comfort zone they are willing to go to get more of it.  Teaching […]

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 […]
