Welcome to Grounded Math

This website is dedicated to supplying teachers with mathematics resources and is going to be used by the author to help collect his ideas so someday he may publish them. With that in mind, the author gives free use of the materials on this site to all, but asks that you contact him if you wish to reproduce something outside of your normal classroom usage.

The basic plan is to eventually have a plethera of good ideas: complete with basic lesson plans, computer files (especially files for the Promethean Activboard and all of it's peripherals), graphics describing various teaching ideas, tons of worksheets, and more. Be sure to check back every so often as new content will continue to be added as it is produced.
