Welcome to Sine of the Times!
This blog began as a home for Key Curriculum Press, the publisher of The Geometer’s Sketchpad, Fathom, Discovering Geometry, and countless other innovative products in mathematics education, to share its 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’s successor to The Geometer’s Sketchpad.
