Illustrated room activity · streak power-ups coming to PrepBox.
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.
An illustrative session. Help depends on the booked session or membership. Classmates’ attendance varies.

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 is the permanent free option. Your introduction includes two weeks of Large Table benefits: two booked sessions, Uni help and marking. Ongoing Uni tutoring and teacher-led instruction are optional paid support.
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.
Can my child drop in whenever they want?
The current free-session offer uses booked times. Join during your reservation. We cannot promise that classmates or a tutor will be present at other times.
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?
Open Math Studio is the permanent free option for independent practice, lessons and worked solutions, with no expiry. Keep the same account. Choose a paid membership only if you want ongoing Uni help, marking or teacher-led instruction.
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.
Does an open-room seat include a teacher?
No. Individual teacher attention belongs to booked tutoring or a paid teaching plan. General access to the room is different from personal instruction or supervision.
Give math some company.
One free account. Two weeks of support, including two sessions and marking. Then keep independent practice free — no subscription required.
