Classroom Rules • Same rules as Mr. Lopez, including: • Do class work and participate • No bathroom breaks • No getting out of seats • No cell phones • No throwing objects • Controlled talking only • And other normal classroom rules (no cheating, etc)
What is controlled talking? • Appropriate noise level • TRY IT: Everyone start talking very quietly and grow gradually louder and I’ll raise my hand when the class is too loud • If the class is loud, talkers will be punished
