At the beginning of the school year I plan to laminate the 3rd grade sign and take a picture of each student holding it. It's a great way to show growth throughout the year (if you also take an end of year picture)-- or just good for classroom management.
Download includes 2 signs for 3rd grade:
"First day of 3rd grade"
"Last day of 3rd grade"
