About Us

This webpage was created by the 7th grade pre-algebra students at Butcher Educational Center.  We are members of the Middle School Math and Science Technology Center (MS2TC) program in the Warren Consolidated School District.

Our Goal

Our goal is to share our knowledge of pre-algebra with students who may need additional support in these areas.  We used Khan Academy as our model.  Our initial focus will be on number sense.  We hope you find it useful!
