Grades 6 to 8 · Common Core

Math you can turn, break and fix.

Kids learn slope on a skateboard ramp, volume in a fish tank and equations at the fair. Every lesson is a 3D scene with a narrator, practice with hints, and a tutor that never just hands over the answer.

Most kids memorize the formula.
Few ever see where it comes from.

Math in 3D puts the idea in front of them first: cubes filling a tank, a ramp getting steeper, tickets adding up to 18. The formula shows up after, and it finally makes sense.

See it

A real 3D scene they can turn with a finger. Numbers on the board change as they move things.

Break it

Each lesson has three classic mistakes built in. Press one and watch the answer go wrong, and why.

Solve it

Six problems per lesson, each with three hints, and a three-question check at the end.

The lessons

Six lessons. Six everyday places.

Each one is explained like you'd explain it to a 9-year-old, with things kids already know.

How a lesson works

Five moves, about ten minutes.

  1. 1

    Play

    A narrator walks through seven short steps while the camera moves to each part.

  2. 2

    Try it

    Sliders and buttons change the scene. The math on the board updates live.

  3. 3

    Break it

    Three common mistakes, shown on purpose, each with a plain reason it's wrong.

  4. 4

    Your turn

    Six problems. Type an answer, climb the hint ladder only if you need to.

  5. 5

    Check

    Three quick questions. Get all three and the lesson is saved as done.

The tutor

A tutor that makes the problem smaller. Never does it for them.

  • Hints, not answers. Three hints per problem, written ahead by teachers. It gives one at a time.
  • Knows the usual mistakes. Type 0.25 for a slope of 4 and it says you divided across by up.
  • Sticks to math. If a child says something worrying, it points them to a grown-up they trust and the 988 line.
  • Rules live in code. Students can't talk it out of them. Teachers set the rest.

For teachers

See who's stuck before the test does.

  • Every student, every lesson. Done, in progress or not started, and who hit a common mistake.
  • "4 students may need help." It names the lesson and the mistake, so you know what to reteach.
  • Assign in two taps. Pick a lesson and a due date. It shows up on each student's dashboard.
  • Present full screen. Press Play and let the narrator teach while you pause and ask the class.

Questions teachers ask.

Which grades and standards does it cover?

Grades 6 to 8, mapped to Common Core. Today: 6.G.2 (volume), 7.NS.1 and 7.EE.4 (negative numbers and equations), and 8.EE.5, 8.EE.6, 8.EE.8, 8.F.3 and 8.F.4 (slope, lines and solutions). More lessons are added every week.

Does it work on Chromebooks, iPads and phones?

Yes. It runs in the browser with nothing to install. Phones and tablets get a lighter version of the 3D scene so it stays smooth.

Will the tutor do my students' homework for them?

No. In homework and practice it only gives the hints written for each problem, one at a time. That rule is in the code, so a student can't talk it out of it.

Where does student data go?

In the demo, nowhere: everything stays in the browser. In a school, accounts and the tutor run on the school's own lab box, and student questions are never sent to us.

How long is a lesson?

About 10 to 12 minutes with the narrator, plus practice. It works as a warm-up, a full class activity on the board, or homework.

Can I start a pilot with my class?

Yes. Open the teacher demo to see everything, then ask us about a pilot. We set up your classes and add the lessons you teach next.
