Plotting Straight Lines from Two Points

Students begin to plot equations in the form ax + by + c = 0 substituting in x =0  along the y axis and y = 0 along the x axis .  The resultant line is joined between the two coordinates to represent the function.  As learning progresses students consider the gradient and intercept of the graph from its equation.
Differentiated Learning Objectives
  • All students should be able to plot a straight-line graph in the form ax+by=c using two points on the axes.
  • Most students should be able to plot a positive or negative graph in the form ax±by=c using two points on the axes.
  • Some students should be able to plot graphs in the form of ±ax±by=±c where the variables are not integers.

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 […]
