Handwriting from the existing PrepBox demo, replayed in an illustrative student workspace. Classmates, progress indicators and help are examples. This is not connected to a live student session.
Read the handwritten work
Volume: V = ⁴⁄₃πr³ = ⁴⁄₃π(4)³ = 4π(64)/3 ≈ 804.25/3 ≈ 268.08 cubic units. Surface area: SA = 4π(4)² = 4π(16) = 64π ≈ 201.06. The recorded attempt labels surface area “cm²”; the question uses generic units, so the tutor example asks the learner to check that label.
Your child chooses a character and joins at their booked time. Other students may be working in the room.
About this preview
An illustrative session with fictional classmates. Streak power-ups are coming to PrepBox. The recorded sphere attempt comes from the existing PrepBox demo. Uni’s algebra example and Min’s portrait with written feedback are scripted teaching illustrations.
The sphere attempt gives about 268.08 cubic units and 201.06 cm². The tutor asks the learner to use square units, as the question specifies generic units. In the separate algebra example, Uni checks 3x − 6 = 2x + 5 and x − 6 = 5, notices x = −1, then draws a bar showing 6 taken away and 5 left. The student corrects the answer to x = 11.

What happens in the film
Leo builds a run of correct answers. His fire turns gold, then blue. His classmates look up from their work and cheer. The film ends with: “Math, more fun together.” Music and power-up sounds accompany the animation; its captions are visible in the picture.

Before you start
A few practical details.
What comes with the free account?
Independent practice, automatic marking, XP, streak feedback, lessons and worked solutions are free with no expiry. No booking is needed to practise on their own. The account also starts with two weeks of Uni help and two booked Large Table sessions.
How do we get started?
Choose “Create your free account” and use a parent or guardian email. Create or select your child’s account, then book the included sessions. You do not need a separate signup for the free option. Join on an iPad with a stylus at the booked time.
Is marking included on the permanent free plan?
Yes. Automatic marking is free forever. Your child submits their work, gets feedback and earns XP and streak progress as they practise. This continues after the two-week introduction; no paid membership is required. Ongoing Uni guidance and teacher time are separate, optional support.
When can my child practise or join classmates?
Independent practice: anytime, with no booking. Open their work, lessons and worked solutions whenever they want to practise.
Shared-room sessions: join at a booked time. The introduction includes two sessions to book within the two-week window. Classmates’ attendance varies; a free account does not promise an always-occupied room or on-demand tutor.
Which grades can join?
Registration accepts Grades 1–12. Available practice and session suitability depend on your child’s grade. If you are unsure which group fits, ask Min before booking.
What does my child need?
An iPad with a stylus for handwritten work. Use the parent or guardian email to get started. Ask Min about equipment options if you do not have an iPad.
What do other students see?
The studio represents students with characters. This demonstration uses fictional students. For questions about your child’s information and account, read our privacy policy or contact us.
What happens after the introduction?
Keep the same account for free independent practice, automatic marking, XP, streak feedback, lessons and worked solutions, with no expiry. The included Uni help ends after two weeks. A paid membership is optional, and you are not automatically subscribed.
When does the introduction start?
Your two weeks start when the student account is created. Book both included sessions within that window. When it ends, the same account continues on Open Math Studio for free independent practice. There is no automatic paid subscription.
When is a tutor available?
Tutor attention is available during your booked tutor session or according to your paid teaching plan. Independent free practice does not include a tutor on demand.
