Provide clear verbal prompts
Avoid vague prompts such as “What is the answer to this question?” Even if you are writing something down and you think everyone should be able to see it, reading the information aloud will help the class to stay on track with what you’re teaching. Likewise, if you show pictures or slides describe the images. Limit pointing to a specific element or referencing items by saying “this” or “that”. For example, instead of pointing at the board and saying “this divided by that”, say “distance divided by time”.
