#### What's Included

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

The main concept throughout the lesson is the sum of angles on a straight line being equal to 180° and those about a point have a sum of 360°.  From this students go on to discover vertically opposite angles and angles about a point.
##### Differentiated Learning Objectives
• All students should understand that a straight line has a sum of 180 degrees.
• Most students should be able to calculate missing angles on a straight line.
• Some students should be able to calculating missing angles about a point.

Angle Properties - Foundation

Angle Geometry - Higher

#### 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 […]
