Angles in a Triangle

Students begin by investigating the sum of the angles in different types of triangles.  As learning progresses they apply the sum of angles in a triangle and other geometrical properties to solve more challenging and complex problems.
Differentiated Learning Objectives
  • All students should be able to calculate the remaining angle in a scalene and right angled triangle when given the two.
  • Most students should be able to use the properties of triangles to calculate angles in isosceles and equilateral triangles when given one.
  • Some students should be able to calculate angles in compound shapes involving multiple types of triangle.

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 […]
