Finding the Equation of Straight Line Graphs

The start of the lesson is used to review calculating the midpoints of line segments with different gradients.   The development phase builds on this by deriving the equation of a straight line graph.

As learning progresses students use algebraic techniques to derive the equation of a line segment represented graphically and in the plenary, between two pairs of coordinates.

Differentiated Learning Objectives
  • All students should be able to derive the equation of a positive straight line graph in the form y = mx + c
  • Most students should be able to derive the equation of a straight line graph in the form y = mx + c
  • Some students should be able to derive the equation of a straight line graph using two pairs of coordinates.

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.
