The Math Machine is dedicated to the development of virtual mechanicals for use with mathematics instruction, especially for elementary-level core-aligned curriculum. Our calculator, Megapro Calculator 5000, is available as a free app on the iOS App Store, and a beta version of our supplementary math curriculum for second graders is available for free from http://second-grade-robots.org.
Would you like to help us design a new kind of math curriculum that is more intuitive, more engaging and more social than any other? If so, then please register as a site member using the sign-up link and partcipate in our forums, where we will be discussing successful and not-so-successful aspects of our current release. We would love to benefit from your ideas and feedback.
If you would like help using our activities with your second-grade child students, then please contact chris [AT] the-math-machine.org to receive the maximum possible assistance.
