You have two options

You have two options. This is an easy way to control childrens' behaviour and make them reflect on what they are doing and what they can do.

For example, when a child is playing with a toy he/she shouldn't be playing with, you can tell him/her: "You have two options: you can put it away in your bag and pay attention, or you can leave it on my desk. "

They will probably choose the first one and keep them in their bags. Remember, it is better to avoid confrontation.
