# Plotting Graphs on a Grid

Students learn how to complete a table of results and plot a straight line graph on a grid in the form y = mx + c .  As learning progress they begin to consider the effect a negative gradient has on the direction of the line.

The start of the lesson recaps finding the equation of horizontal, vertical and diagonal straight line graph using the properties of a square.  The plenary challenges students to find a pair of coordinates that lie along a line using algebraic methods.

##### Differentiated Learning Objectives
• All students should be able to plot a straight-line graph in the form y = x ± c
• Most students should be able to plot a straight-line graph in the form y = mx + c
• Some students should be able to recognise, sketch and produce graphs of linear functions.

#### Surface Area of Cylinders

When I teach how to find the surface area of cylinders I like to add a constant level of challenge and enjoyment to the lesson.  Rather than repetitively calculating the surface area of a cylinder I introduce more complex cylindrical shapes.

#### 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 […]
