Change an activity so that preschoolers can work independently, but you can be there for a few moments to say the Bible phrase and have a short conversation. Write Bible phrases on slips of paper and place around the room. This will help you remember what they are as well as remind you to use them. When your mind is in a whirl, visual reminders really help. Intentionally rotate to every area of activity making conversation and using the Bible phrase.
Every teacher needs to be familiar with every activity offered.
This is the only way we have found to give attention where it is needed most at the moment it is needed. If you are fortunate enough to have last-minute volunteers, assign them to a specific area, give brief instructions, and call attention to the Bible phrases posted around the room. Tell the volunteer to use the phrase in conversation with the preschoolers. While you are rotating around the room, listen to see if they are using appropriate conversation. If you do not hear the Bible phrase in the first few minutes, you may need to rotate to that area and model it for the volunteer.
