Routines for turning in homework Check the answers to your homework with my notebook. This is not a time to mark your paper, but just to do a quick check and check for understanding for yourself. Label your homework with your name, homework number and the page and exercises assigned at the top. Turn in your paper on the folder labeled “homework #1”, there is also a folder labeled “contract”, place your contract there. Have a seat when you are done and take out your student journal, we will continue any exercises we didn’t finish from the day before.

Graph this with students, create a table when necessary.
