Welcome to Sine of the Times!

This blog began as a home for the educational specialists at Key Curriculum Press to share their thoughts and insights about mathematics education.

Since 2013, Daniel Scher and Scott Steketee have used this space to present hundreds of curriculum ideas across grades K-12 that showcase Web Sketchpad, McGraw Hill Education’s successor to The Geometer’s Sketchpad.
