I take attendance quickly by having a poster with pockets in which each student has a number on the pocket (like their number on your roster). Then I place an index card with their name and a sticker or picture on it and their corresponding number. Every morning, I have them bring me their card as they come in the door. I can then use the card to draw for who is going to be a helper, and I know which children are present. I can quickly look at the pockets which still have a card in them to see who is absent.
