Lengths in Right-Angled Triangles

Students learn how to use Pythagoras' Theorem to calculate missing lengths in right-angled triangles.    As learning progresses they solve more complex problems involving triangular shapes.
Lengths in Right-Angled Triangles Differentiated Learning Objectives
  • All students should be able to use Pythagoras’ Theorem to find any length of a right-angled triangle.
  • Most students should be able to use Pythagoras’ Theorem to find the height or base of an isosceles triangle.
  • Some students should be able to prove Pythagoras’ Theorem using algebra.

Teaching Reciprocals of Numbers and Terms

To introduce teaching reciprocals of numbers and terms I begin the lesson explaining that everything has an opposite.  The opposite of shutting a door is to open it.  The opposite of saying hello is to say goodbye.  Numbers have opposites too we call them reciprocals.

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.
