The Math Open Reference  illustrations are interactive and animated. The teacher has, in effect, a vast library of 'digital manipulatives' with which to demonstrate concepts using a computer and projector. The teacher also knows that the students can use the exact same manipulative themselves outside the classroom. Apart from being fascinating to see and use, the interactive tools permit far better visualization and understanding. It is very difficult for example to experiment with the way a plane intersects a cone using a white board or even physical manipulative. It is almost impossible for the student to do it alone. 

Lesson Planet provides a convenient way to discover and share innovative lesson plans. The Lesson Planet solution helps teachers find lesson resources, correlate them to standards, and organize their curriculum. Lesson Planet’s tools offer teachers a time-efficient way to inspire their teaching with fresh ideas.
