Please choose the correct ending to complete the given sentence: Education and Communications: [header] How to manage a classroom [title] Simplify your rules. [step] Every classroom needs to have simple, clear expectations for the students in terms of behavior and your rules. Younger students will typically benefit from having the class rules simply worded and posted visibly, while older students may benefit from getting them in writing.

Ending1: Set clear boundaries about what students should and should not do (within the classroom, of course), so that you can enforce them regularly. [substeps] You might maintain every classroom until the semester is over. Ending2: [substeps] For example, if your classroom rules involve two lemus toilets, and the secondary toilets are pig pens, then let students have these, too. Set your expectations as simple as possible and don't make a lot of unnecessary adjustments to simple and basic rules. Ending3: The principal or other trusted authority for your school must be meeting these rules. The first step is to set clear and detailed expectations about how students should behave in the classroom, and then ask the students to do the same. Ending4: [substeps] Aim for having no more than five big rules, or categories of rules to go over, or you'll lose them. [title] Only use specific and important rules that you'll be able to enforce.
