Completing the Square

The method of Completing the Square is introduced through recognising a need to solve a quadratic when it can not be easily factorized.Throughout the main teaching phase there are numerous examples for the teacher to model plus additional equations to be practiced by the students.
Differentiated Learning Objectives
  • All students should be able to solve a quadratic equation in the form ax2+bx+c=0 where a equals 1 using the method of completing the square.
  • Most students should be able to solve a quadratic equation in the form ax2+bx+c=0 where a does not equal 1 using the method of completing the square.
  • Some students should be able to use completing the square to solve equivalent quadratic identities.

Calculating the Volume of a Pyramid

When calculating the volume of a pyramid we can substitute the values of the length, width and perpendicular height into the formula V = 1/3 lwh.  In my experience this is often provided for the students with little explanation as to why a volume of a pyramid is exactly one third the volume of a […]

Solving 3D Problems using Trigonometry

When teaching solving 3D problems using trigonometry we begin the lesson with a recap of Pythagoras’ Theorem and the three trigonometric ratios.  We do this by matching the ratio and equations to the respective right-angled triangle.   Students are encouraged to work in pairs and to show the diagrams as part of the working out on […]

Rounding to a significant figure

When I teach rounding to a significant figure, I ask the class to discuss in pairs or small groups a definition for the word significant.  It is a word that all the students have heard before but not all are able to define. After 2 or 3 minutes of conversation I ask the students to […]
