During the summer of 2013, Joel Berman did some great work mapping free and open content to the state’s math competencies (Thanks Joel). Below you will find a variety of free resources you can use with your students. You are also free to share these resources with students interested in improving their math skills.

To begin, here is a creative commons licensed text book chapter on the subject of Whole Numbers. You can get to the chapter by clicking on the image to the left or by following this link.

Beyond the text chapter, here are some other links to a wide variety of video-on-demand from Khan academy and some other resources. The first two videos are embedded for easy access and to give you an idea of what the videos look like. You can get to the rest by simply clicking on the links. Enjoy!
