What is I Know It?

"I know It" is a math practice website for students in Kindergarten through 5th grade.

When students answer math problems correctly, an animated character celebrates their success by jumping and dancing. When they answer incorrectly, they are presented with an easy-to-understand graphical explanation.

Teachers who are members can set up student accounts, assign lessons, and monitor their student's progress.

Can I try the site for free?

Yes, you can sign up for a 30-day free trial. There's no catch, and no commitment.
We do not ask for a credit card information when you set up your account.

Can I try the lessons without signing up or logging in?

Students can answer up to 12 questions per day before logging in is required. Their results are not tracked unless they are logged in.

Members who log in can create accounts for each of their students, view student score, and track their progress.

My students can see the grade level of each lesson. Is it possible to hide this?

When a student logs in with his or her own account, grade levels of the lessons are hidden.

Is there a feature that allows questions to be read aloud?

Yes. Simply click the little speaker icon next to the question text.

Is there a "work space" feature that allows students to show/draw their work on screen?

Yes. Simply click the pencil icon and the work space will appear.

Who built this site?

We're the same team that built and operates SuperTeacherWorksheets.com. Our team consists of a handful of teachers, graphic artists, computer programmers, and customer support staff.

All questions were written by experienced, professional elementary school teachers.
We've even tested the site with students in a classroom setting.

What devices can I use to access "I Know It."
