Welcome to Sine of the Times!

This blog began in 2010 as a home for the educational specialists at Key Curriculum Press to share their thoughts and insights about mathematics education.

Key Curriculum no longer exists, but Daniel Scher and Scott Steketee, two of its employees, have kept the blog alive, showcasing examples of the newest Sketchpad technology, Web Sketchpad.

You can reach Daniel at dscher(at)icloud.com and Scott at stek(at)geometricfunctions.org.
