Geometry Comment from user:
"There are simply too many choices of great activities. I wish I had more time to do them all with my students. I remain amazed at the quantity and quality of your resources! Nice work!
     With over 60 years of combined teaching experience (to date), we offer to you all of our creative and engaging materials and strategies which have been, and continue to be, successful in the mathematics classroom.  Also included are materials we have shared with educators at teacher conferences and workshops and our personal teaching methodologies. We chose this subscription format because it allows us to continually add and update materials, in a format which brings you the largest number of materials in the most cost effective way.

Please refer to the complete Terms of Use.
Rigid or Not Rigid Transformations
  Students graph reflections, translations, rotations, dilations and combinations to determine if length and angle measure are preserved.
Vertical Angles and Rotations
  Students supply reasons for a transformational proof that vertical angles are congruent. 
Pair Share - Beginning Trig Twisters
  Students work in pairs to solve each side of the worksheet. When finished each side will yield the same answers, but not in the same order. Topic: Beginning Trigonometry
Slope Criteria for Perpendicular Lines
  Students supply reasons for the steps in a geometric/algebraic proof of the concept that perpendicular lines have negative reciprocal slopes (both ways).
Spheres in Play
Students find diameter, radius, surface area and volume (forward and backward) for a series of sports' balls and find density to see if they float in water.
Ah Bach - Quadratic Systems
  Students answer multiple choice questions pertaining to systems: linear, linear-quadratic (parabola and circle). Answers are used to decipher a hidden message.
(Answer sheets for these materials are included in the subscription.)
