This GUIDE explains how teachers (and professors) can best use MazeFire games, both in their classrooms and for home-play (with friends or for review/exam-prep). Most games at MazeFire.com are in the STEM field, but we are also beginning a liberal arts collection (History e.g. is very well suited for Maze Games). 75% of our games are free, so teachers with internet connections can just *click-and-play* them in class--but we urge teachers to first complete each maze and review the Q&A page where explanations are provided for all questions (rooms) in the maze: our games ARE challenging! This TEACHERS GUIDE gets into a bit of Synaptic Learning Theory (SLT) to explain why maze games will help students transition from *recalling* facts to *knowing* them. There is also a free/complementary STUDENT GUIDE which goes into more detail about navigating our mazes and how students will benefit.
