# Scale Drawings of Bearings

Using their knowledge of triangles students learn how to construct scale drawings of bearings.  As learning progresses students move from constructing scale drawings of bearings to interpreting diagrams using ratio.

The start of the lesson recaps calculating angles in scalene and isosceles triangles.  The plenary challenges students to apply additional construction techiniques such as bisectors to find the bearing between two towns.

##### Differentiated Learning Objectives
• All students should be able to use ASA to construct and interpret bearings and scale drawings.
• Most students should be able use ASA and SSS to construct and interpret bearings and scale drawings.
• Some students should be able to construct and interpret bearings and scale drawings.

#### 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 […]
