You always want to nip small problems early before they become larger problems. Developing an effective plan to discipline your students is important for effective classroom management.
Three problems that seem small, but are actually quiet big are 1) Students shouting out, 2) Students wandering around the classroom, and 3) Students that need an attitude check or a keep-it-clean language reminder.
To keep things simple, I made three behavior cards, which you can copy onto different colored papers. (The sample image shows all three, but when you download this product, each type is on it's own page for easy copying.) The first is for shout outs, "Blurt Alert." The second is for students who visit other lab groups or simply can't remain focused, "Wandering Warning." And the third is for any negative behavior such as bad language or a not-positive attitude, "Positive Prompt."
How to Use Behavior Cards: The first incidence, I simply place a card on the student's desk to let them know their behavior did not go unnoticed. A visual reminder on the student's desks helps remind them to not act out again. The second offense calls for a time out. The third, parent contact and a detention.
Using the Badges: Additionally, I also made some matching badges you can use as a data log to monitor you classes' progress. I added positive badges as well so your data wall/board is not all negatives, but positives too. You can print and cut out the circles and create a large poster or simply use a dry erase board with making tape for the lines.
