Hi,

TenMarks has launched a math practice and learning program for grades 3 - High School and as of today, it’s FREE for teachers to use in class or for their students to use at home.
The TenMarks approach gives students a variety of problems on each topic, and ability to use hints if they need a little nudge, and immediate video lessons for them to refresh and learn the topic – on the spot. The end result – students refresh what they know and learn what they don’t.

Teachers choose their own curriculum (mapped to state standards), assign work to students, have it automatically graded immediately, review individual and class performance, and most importantly, take immediate action. TenMarks is super effective and real easy to use – it was designed with the help of math teachers across the country. What’s more - it's FREE for the entire class!
