How to use these Year 9 angles in polygons starters

First, give yourself about 30 seconds for each question. Then write the answer down before you check it. If an answer is wrong, look at the angles in polygons lesson again. After that, move on to the angles in polygons worksheet for longer questions.

Finally, repeat these starters a few days later, because regular practice makes the facts automatic. Moreover, all the pages of this chapter work together, so you can move between them at any time. For example, many pupils read the lesson on Monday, practise on Wednesday and test themselves on Friday.
