Hang these lunch count cards on a magnetic surface or pocket chart. Write each of your students' names on the red name tags and hang them under "Absent". Every morning, students sign in by moving their name to what they want for lunch. Once all of the students are signed in for the day, you can easily take lunch count and attendance by seeing whose name is left under absent.
I suggest printing on card stock and laminating so that they are durable and last the entire year.
