100 Ideas: Dingbats
This is idea No. 42 in the book!
Display some examples of dingbats as a game for learners. It will help to start with some that are not related to your subject before you introduce a few that are. These are easy to find online but I have an example starter presentation on the blog post that accompanies this idea. Challenge learners in pairs or small groups to solve the dingbats you display on your board.
A downloadable resource is available here to help you deliver this activity in your classroom.
