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.

Solving Inequalities using a Number Line

Students should be able to represent the solutions to an inequality on a number line, using set notation or as a list of integer values.  Here’s how I teach using the balance method for solving inequalities using a number line. Matching inequalities, Number sets and Number Lines At the start of the lesson students recap […]

Practical Tips for Using Mini-Whiteboards in a Mathematics Lesson

In this blog I will share some practical tips for using mini-whiteboards in a mathematics lesson.  I use mini-whiteboards nearly every lesson because they help the students show me the progress they are making.  When I understand what the misconceptions are I am able to address them in subsequent examples as part of my feedback.  […]

Showing Progress during a Mathematics Lesson

Demonstrating student progression during a mathematics lesson is about understanding the learning objective and breaking that down into explicit success criteria. Using Success Criteria Take, for example, a lesson on calculating the area of compound rectilinear shapes. The intended learning objective was written on the main whiteboard. Success criteria were used to break down the individual […]
