Presentation l l l Very important Communicate math with others Good practices reduce the chance of making accidental mistakes.

Non-Standard Presentation

OK Presentation

What? l l My high school math teacher told me to do it that way! Now you are saying it is not standard? (A story from last year!)

Oh No! l (Some) High school teacher mentality… “once you graduate, it is not my problem”

What? l l If you do not believe me, look at any college math textbook! You can blame whoever told you to do that. It is now your responsibility to use the standard presentation!

Practice l l Be sure to have all the steps and details. You must have all the steps and presentation done correctly before you can leave. I will check each paper individually!!!!! Finish the one HW problem for tonight.
