Lesson Materials – 3 new sets – Geometry Gizmos

176DETHappy 2013, Gizmologists! To kick off the new year, we're happy to announce 3 new sets of Lesson
. Again, we've been working in the realm of geometry:

Perimeter and Area of Rectangles

Classifying Quadrilaterals – Activity B

Similarity in Right Triangles

As always, our updated Lesson Materials have 4 documents (Student
Exploration Sheet, Answer Key, Teacher Guide, and Vocabulary Sheet),
each available as a .doc or .pdf. (You'll need to be logged in to see all four documents.)

We hope these materials help your students dig into the concepts of geometry in a real inquiry-based way. Gizmos are great "what if" tools, and the Student Exploration Sheets encourage students to dig into the concepts themselves: What is always true about these figures? Under what conditions?

This bring us up to 48 math Gizmos with updated Lesson Materials. Stay tuned, as we'll keep rolling out more throughout the year!

If you'd like to try these Gizmos, or any of the others in our library, take a free trial today.
