#### What's Included

• Smart Notebooks Presentation
• Activ Inspire Flipchart
• Lesson Plan
• Microsoft PowerPoint Presentation
• Differentiated Worksheet

The start of the lesson is used to recap calculating the gradient of linear functions.  The development phase teaches students how to calculate the gradient of parallel functions.  As learning progress they are challenged to derive the equation of linear graphs.
##### Differentiated Learning Objectives
• All students should be able to understand that parallel lines have the same gradient.
• Most students should be able to calculate the equation of a line that is parallel to another.
• Some students should be able to rearrange equations in the form ax + by + c = o to calculate the gradient of parallel lines.

#### 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 […]
