My tip is to help organize lunch count and attendance in the mornings. When my students enter the room I have Popsicle sticks with their names on them lying on the table by the door. There is also a monthly menu taped to the table and three cups labeled hot lunch, salad bar, and not eating/sack lunch. Students place their Popsicle stick into the cup that shows their choice for the day and then they take their seat to copy the morning work from the board. While they are doing this, I can count the sticks in each cup and fill out the lunch count slip. It's also very easy to tell who is absent. All this is done without roll call or disrupting the quiet thinking time. Thanks to Harry Wong and his Effective Teacher ideas.
