New Math Lesson Materials Published

We've just published 2 new sets of Lesson Materials for two of our most popular math Gizmos!

Polygon Angle Sum - Activity B

Quadratics in Polynomial Form - Activity A

As usual, each set of updated Lesson Materials includes 4 documents (Student Exploration sheet, SE Answer Key, Teacher Guide, and Vocabulary sheet), all of which are available as a .doc or a .pdf.  (Note: You will need to be logged in to see all the documents.)

This brings us to 20 math Gizmos with updated Lesson Materials (well, 60 if you count the more modern "purple ones" that have never had anything but Lesson Materials). We still have a long way to go in this project, but there's plenty of progress happening "behind the scenes."

We hope these new Lesson Materials are a help to you and your students - lots of good explorations and thought-provoking questions here.
