TenMarks is a service that offers an online mathematics program designed to supplement your in-classroom mathematics instruction. I tried the service when it launched a couple of years ago. Today, I revisited it when I learned that they now align all of their practice activities to Common Core Standards.
Within TenMarks teachers create class rosters and accounts for their students. After creating rosters teachers can assign practice problems to students. Teachers can assign problems based on the Common Core Standards that their students are trying to reach.
Applications for Education
TenMarks could be an excellent resource for elementary school and middle school teachers. TenMarks provides an efficient way to provide practice problems and track students' progress. The information gathered about students' progress can be used to influence the creation of lesson plans tailored to students' specific needs.
