There are 366 different Starters of The Day, many to
choose from. You will find below some starters on the topic of Trigonometry. A lesson starter does not have to be on the same
topic as the main part of the lesson or the topic of the previous lesson. It is
often very useful to revise or explore other concepts by using a starter based on a
totally different area of Mathematics.
