These table signs are used to help with classroom management and student engagement. The students are numbered 1, 2, 3, or 4. They are also given a letter A or B. This creates an easy way for the teacher to announce, "Student 3 at each table, pass out the rulers!" or "Talk to your shoulder partner about this math problem, partner A goes first."
No longer will you deal with students arguing about jobs or spending the entire discussion time deciding who should go first. Problem solved! I hope you enjoy it!
