Rachael Boucher at MES found a great PC PDF creator called Nitro Reader. You can download it free and then there is an icon on your desktop that you drag the word file onto and it instantly creates a PDF. http://www.nitroreader.com/
One of my favorite websites in Khan Academy! I first used it last year when my daughter in high school was taking a Geometry class and needed help with angles. I was a little rusty on how to calculate transverse angles so I went to Khan Academy and within 5 minutes was able to watch a quick video tutorial. It was amazing all the topics available not only in mathematics but in other subjects as well! Now he has another section on the website for students to practice the concepts in math. Teachers can sign up as their coach and view the progress of the whole class and it's all FREE!

"Maybe you have already seen this but I am flipping out over this website I found. It goes with the NWEA scores. Find your student's area(s) of weakness. Click on the range for their score and it takes you to online games to practice that area."
