There are 366 different Starters of The Day, many to choose from. You will find below some starters on the topic of Functions. 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.
