This resource is designed to be used during the main part of a lesson for any topic. It is a power point slide which shows the students colour coded tasks. Students can choose a task, tasks can be allocated according to ability, or students can progress through the tasks. The teacher can circulate around the room and assess students as required. The only resources needed are a text book or information on the topic and an exam question and mark scheme. The plenary can be to use questions and answers written by the students during the lesson to test the class. This can be used repeatedly for any topic and is great for observed lessons.
