This activity could be used in several ways, e.g.:
- as an introductory lesson, to check what students already know
- as a check-up immediately after teaching basic angle types
- as part of a check-up at the end of a unit of work on angles
- with ESL students or those who have trouble spelling
- in any other way you see fit!
There is another version of this activity, using cards instead of Powerpoint. Which of these ideas you select and use will be determined by the make-up of your class. If students are at the same level, the Powerpoint might be more fun. If there is a real range of abilities, however, you would probably opt for the card version.
