An innovative supplement to classroom lectures...
Rick Medeiros has created many Powerpoint slide shows for arithmetic and algebra for use in the classroom. Some are useful primarily for the teacher and some are challenges for the student.  The latter slideshows can be used as a lesson opener or review or just a fun challente. Rick has many more ideas and shows and is more than willing to share them with you!
