Why we need proceduers and rules in classrooms?

So many things could happen without rules. For example, let's say the teacher says no phones during testing. Sounds reasonable, right? If students didn't follow that rule than there are a lot of distractions during testing such as students surfing the internet. Rules and procedures are set so everyone can have a calm and peaceful school day. Rules like no pets, raise your hands for a question, inside voice, and keep your hands to yourself are rules that should be followed. How would you like it if someone brought a large slobbery dog to your party? And what if you're rules were no pets allowed. See? Rules are important.
