Students learn how to generate and describe sequences on a term-to-term and position-to-term basis. Learning progresses from plotting and reading coordinates in the first quadrant to describing geometric sequences using the nth term.
use simple formulae
Pupils need to be able to use symbols and letters to represent variables and unknowns in mathematical situations that they already understand, such as:
How to introduce the sin, cos and tan trigonometric identities.
How to teach calculating the original amount after a percentage change.
The importance of the range when comparing comparing datasets.
