# 3D Trigonometry

To solve problems involving trigonometry in 3D shapes students are taught to identify 2D right-angled triangles and apply the Sine, Cosine and Tangent ratios.  As learning progresses they consider square based pyramids in addition to cubes and cuboids.
##### Differentiated Learning Objectives
• All students should be able to calculate a length in a 3D shape using 2D representations of right angled triangles
• Most students should be able to calculate an angle in a 3D shape using 2D representations of right angled triangles.
• Some students should be able to calculate a combination of length and angle in a 3D shape using 2D representations of right angled triangles

#### 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 […]
