One more thing! Do and does are often hard for students to get. Try a different activity.
Do your students all come on time? At my school, MANY students come late. It's not unusual for students to come 30 minutes late. So I never start a new grammar point or a new lesson or topic in the first 30 minutes. I do other things in that time...things that aren't absolutely essential. I sometimes give additional practice on something they learned before, or maybe do review.
