Now here's a slightly more formal approach to the use of the materials for those who are concerned.
Unless noted otherwise on the materials, this site and the related resources were created by Mike Petty. Permission is granted to use them as follows. If you have any specific questions, please don't hesitate to contact the author.
For Teachers
As long as the resources include a link back to this site or my blog (Classroom Games and Tech), clearly indicate they were made by Mike Petty and not be sold for profit, teachers have permission to:- Modify any resources created by Mike as needed to fit their lessons.
- Share the resources (even in modified forms) with other educators.
About the Games Students Create
Each Game Design Project Pack will have a section at the bottom of the page to address permissions for that particular game. In general, the games students create based on Mike Petty's games can be shared in any way they like, including for profit, as long as any webpages, files or printed rule booklets and boxes give credit to Mike Petty for designing the base game.
