The nine magic tricks within this site are categorized by card tricks, Calculational Wizardry tricks, or Geometry and Topology tricks. The tricks were presented by Larry Dennis, who developed and now maintains the Cyberspace Middle School page. MathMagic Included here are many interesting and challenging math problems. The purpose of the site is to engage teachers and students in a telecommunications project, although teachers who choose not to participate may still use the site to view current and past math problems. When the teams reach a decision, they post their solution.
Teams are from all over the world.
There is also a discussion group for teachers. Ask Dr. Math Have your students submit a question, only after they check the Ask Dr. Math Archive see if the question has already been asked. Teachers can also use the archive to view previous questions and answers and perhaps stump the class. Questions are answered by mathematicians specializing in elementary level, middle school level, or the high school level.
