with the following comment:
The key to slow enough is comprehension checks. Not the hold up your fingers which tells the teacher a bit but not much.
Instead, do a comprehension check about every 3 questions or so. Comprehension checks take one of these three forms:
1. What did I just say?
2. What did I just ask?
3. What does ____ mean?
Try it. You will then see EXACTLY where your kids are getting flummoxed. Most often it will be due to speed, proper nouns, or not getting the question word.
