Positively Positive!

Notice when someone asks you to do something in a nice way, you're bound to do it more than if you were asked in a negative way?  Yeah, that's the idea with children.  They ARE human beings after all so when treated with respect, they'll treat you back respectfully (HOPEFULLY)!  However, I see way to many adults who treat children like someone less than them.  No, they deserve respect too!

Therefore, using positive statements when asking your students to do something can make quite a difference.

It's not "don't run"  it's "walk please".
It's not "don't talk while I'm talking" it's "please be quiet while I'm talking".

You get the drift!
