Bring curiosity into the classroom
Add ten minutes of curiosity to a lesson: project a simulation, let the class predict, then test it. If you like, set up a class, give assignments and see where everyone is in a single table.

In class, no accounts needed
Ten minutes in class
You can use it without setting up a class. Every lesson page opens its simulation with a prediction question, an order that works well for a class discussion.
- 01
Project
Open the lesson page on the board or a smartboard. The simulation works without an account, so you're not waiting for anyone to log in.
- 02
Predict
Before the simulation starts, a prediction question appears. Take a show of hands; the options come from real misconceptions.
- 03
Test
Invite a student up to the board to change the values. Once an answer is submitted, the server says whether it is right.
- 04
Explain
A short explanation follows the correct answer. Compare it with how the class voted: who thought what, and why?
A good one to try
“Does luck really exist?”
5 steps. Each step fits in a single lesson; you can start with the first step’s simulation.

What's in the teacher dashboard
- Progress table
- For each student: level and XP, streak, lessons and activities completed, quiz average, last activity date, and the status of every assignment: done, pending or overdue.
- Assignments
- Link an assignment to a lesson or a short quiz and set a due date. It marks itself as done when the linked quiz is passed or the lesson is finished.
- Misconceptions
- How students' predictions were spread before each simulation, so you can see which intuitions are common next to the activity's explanation. No names; shown once there are at least 3 predictions.
- You handle password resets
- When a student forgets their password, you give them a new temporary one; no waiting for emails or parents.
- Quiz drafts
- Pick the topic, level, difficulty and number of questions; the AI (Claude) writes a quiz draft and checks each question by solving it again independently. Questions it couldn’t confirm are flagged; you read and edit the draft before giving it to the class. Only the topic, level, difficulty and question count are sent to the AI; no student data.
- Student
- Every student you add to the class is one row.
- Lessons
- How many lessons the student has completed.
- Quiz average
- Average score on the short quizzes they have taken; empty until there is one.
- Assignment status
- For each assignment you give: done, pending or overdue.
- Level, streak, last activity
- Extra columns that show how regularly the student works.
Setting up a class takes four steps
- Step 1
Open your account
Sign up as an educator. Because these accounts can create student accounts, they go through a short approval; you can browse the lessons meanwhile.
- Step 2
Set up your class
Create the class and enter your students' names. You create their accounts; students don't need an email address.
- Step 3
Hand out the cards
Print login cards with each username and temporary password. Every student sets their own password on first login.
- Step 4
Assign and follow
Pick a lesson or a short quiz and set a due date. Who has finished shows up in the progress table.
