I wouldn't say I negotiate as most young children don't really understand that concept. Basically when a student isn't doing what I need them to do, I give them a schedule or a choice...depending upon their level of development/disablity.
A visual schedule/social story would be something like this:
1. Something you want the child to do.
2. (same as above)
3. (same as # 1)
(Student name) is working for (activity of their choice/reinforcer)
I read the story with them and then as they complete the task they can cross it off the list or they can pull the picture off.
Secondly, for students of a higher stage of development, I will use the choice method. I give them the appropriate choices they have and allow them to choose.My 5 year old son is way past the choice stage. He negotiates with me all the time. Every time he wants something, and I say no, he comes up with a compromise (of sorts), tells me and then asks "is it a deal?"
If I say yes, then we have a deal, and i must keep to it, or he gets upset again. If I say no to his deal, then I have to make my own compromise that I think he might agree too. If he doesnt agree, then he cries, has a tantrum, and I just stay firm on my decision, until he calms down.
Some kids can negotiate, some cant. depends on their age, and what they have learned from their parents or the TV. My son loves the game show "Deal or no deal".
