At Home AUP
I suggest to also have an At Home AUP. This will allow your child to know what you expect of them at home. This will help them to be accountable for their actions and know the consequence or reward for their behavior. HERE is a template to help you get started on an At Home AUP!
Your rules and consequences or rewards can be whatever you see fit!
An example of a rule and consequence would be:
Rule: Complete homework before watching tv or playing video games.
Consequence: No tv for the rest of the night or until homework is done.
Reward: After 5 consistent days of completing homework before getting on electronics, you can have a free pass day!
