Properties of Triangles

Students learn about the properties of triangles.  They explore the various unique triangles that can be made on a square and isometric grid.

To begin the lesson students recap the names of common 2D shapes.  In the development phase they are challenged to create siz unique triangles on a 3 by 3 grid.  The end of the lesson challenges them to consider why some properties in triangles are impossible.

Differentiated Learning Objectives

  • All students should be able to identify an isosceles, equilateral, right-angle and scalene triangle.
  • Most students should be able to know the properties of different types of triangles.
  • Some students should be able to create all the unique triangles on a 4 by 4 grid.

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 […]
