Factors

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

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 and consolidate topic by using a starter based on a totally different topic. Some of the most popular starters are shown in the right column below.
