You can learn more about ST Math and try out some of our games for free at https://www.stmath.com/play.
If you work for a school or district, you can request a demo presentation at https://www.stmath.com/demo.
We have a free version of ST Math for homeschool users. You can sign up for an account at www.stmath.com/start. Homeschool accounts are limited to 10 students. They have access to all of our games, but have less robust reporting and don't have access to the intervention content in grades 6-8.
