Enter your code
Ask your teacher for your code. It works on one device for 30 days.
Wrong maths answers never lock you out. Only your teacher can change your code.
🎯 Daily & weekly tasks
Daily tasks reset at midnight Singapore time; weekly tasks reset on Monday. Treats 🍪 come from independent correct answers and tasks — feed them to your animals so they grow up!
📕 My Mistakes
Answer a question on your own the first time and it is fully mastered ✅ — it never comes back. A question you got wrong comes back for 3 retests: after 1 day, then 3 days, then 1 week. Answer it on your own (first try, no hint) each time to move it on — the 3rd independent pass masters it for good ✅. A wrong answer, or a correct answer with a hint, does not count as a pass: the same retest comes back tomorrow.
My collection — 52 cards, 3 series
📷 Photo Album — real animals (16)
Open the Animal Photo Blind Box (60 XP or 1 ticket) to collect a real photo — cats, dogs and other cute animals. Photos are from Pexels (free licence) — tap “Photo via Pexels” under a photo you own to see its source. Each series shows the cards you own plus the next 4 unknown ones; tap “Show all” to see the rest. Photos cannot be fed — only illustrated animals grow.
Teachers only
Students
One student has one card and one code at a time. Generating a new code replaces the old one in the same card.
Question bank
The built-in bank — 285 questions. Tap a grade tab to filter. Teacher-added questions are listed separately under “Added questions” below.
Add a question (from a test mistake)
Assign it to one student only — it enters only that student's pool. The student name must already exist; an unknown name is refused. Teacher-added questions use written steps, not the full Bar Model loop.
