How does Core5 work?

  • Students take a brief placement activity and begin the online program at a starting point that is right for them.

  • Teachers have access to student progress and performance reports, so that they can provide assistance when needed.

  • In addition to the online program, students use paper-and-pencil and hands-on activities for practicing and extending skills.

  • Students earn achievement certificates when they complete levels. These certificates are a great opportunity to celebrate success and talk about newly-gained skills!
