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.

Mathematics OFSTED Inspection – The Deep Dive

Earlier this week, my school took part in a trial OFSTED inspection as part of getting ready for the new inspection framework in September 2019. This involved three Lead Inspectors visiting our school over the course of two days. The first day involved a ‘deep dive’ by each of the Lead Inspectors into Mathematics, English […]

How to Solve Quadratics by Factorising

The method of how to solve quadratics by factorising is now part of the foundational knowledge students aiming for higher exam grades are expected to have.   Here is an example of such a question. Solve x2 + 7x – 18 = 0 In my experience of teaching and marking exam papers students often struggle with […]

How Write 3 Part Ratios

When learning how to write 3-part ratios students need to understand how ratios can be made equivalent. The start of the lesson reminds students by asking which of six ratios is the odd one out.  This is presented to the class as they come into the lesson.    Writing Equivalent Ratios  A few students immediately go […]
