This is the link where you will find the famous Monica’s Math power points. They are excellent for students who need to review the lessons at home. They are also very helpful for teachers when introducing new concepts.

As part of my math classes, I use free math websites to help students. The more visual concepts you add into your math class, the better the understanding of the material. It is difficult to find the right material on the internet since there are so many choices. I created a simple webpage for my students where they can go and use the same sites I use in the classroom. If you would like to check the math sites, please go to http://www.schoolnotes.com/90230/rosemberg.html.
Regarding the Sedona picture, I just thought that it looks nicer than xyz or y=mx+b : )
