***ONLINE PROFESSIONAL DEVELOPMENT COURSES
Designed for teachers who want to implement problem solving
more effectively, these moderated courses led by Math Forum
professional staff take place online using Blackboard Vista
(formerly WebCT) or Blackboard.

All individuals who successfully complete the course will
receive a certificate indicating that they have completed
15 hours of professional development. This is equivalent
to 1.5 Continuing Education Units (CEUs). Current prices

 Tool: Euler line - Math Open Reference
 http://mathforum.org/mathtools/tool/62433/
 John Page
 An interactive applet and associated web page that
 describe the Euler line. It shows a triangle whose
 vertices can be dragged. As you drag them, the centroid,
 circumcenter and orthocenter move appropriately, showing
 that they are always collinear, always lying on the
 Euler line.

 ***FEATURED DISCUSSION
 Tag Game
 http://mathforum.org/mathtools/discuss.html?&do=m&thread=___disc_13171_g-49
 dmt writes, "I think a fun game for younger students would
 be to play 'tag' with the runners and have the students
 determine at what starting positions and step size the runners
 will intersect or 'tag' each other (while running in the
 same direction)."

 ***FEATURED DISCUSSION
 Secondary Math Posters
 http://mathforum.org/mathtools/discuss.html?&do=r&msg=64409
 Mathsoul adds to a discussion, "I read your post some time ago
 now, and amongst other things your message encouraged me to
 have a range of educational math motivational posters
 professionally designed and made available for teachers."
