Trigonometry - Area of Triangles

Students learn how to derive and apply the area formulae for non-right-angles.  As learning progresses they are challenged to apply additional formulae to calculate unknown dimensions.
Differentiated Learning Objectives
  • All students should be able to calculate the area of a non-right-angled if the value of two sides and the adjoining angle are known.
  • Most students should be able to calculate the area of a triangle using a combination of the Cosine and Area formulae.
  • Some students should be able to derive and solve equations using the Area of Triangle formula.

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 […]

Arithmetic and Geometric Sequences

Students learn how to generate and describe arithmetic and geometric sequences on a  position-to-term basis.  Learning progresses from plotting and reading coordinates in the first quadrant to describing geometric sequences using the nth term. This unit takes place in Term 4 of Year 10 and is followed by the equations of straight line graphs. Arithmetic […]
