Tangyuan Math
Tangyuan Math
Become a Math Hero, One Problem at a Time.
Meet Tangyuan, your little rice-ball math buddy. Practice two-digit multiplication at your own pace — or race the clock when you're ready.
Three ways to practice
Practice — untimed
Pick a number range (times tables up to two-digit × two-digit) and 5, 10 or 20 questions. Check answers whenever you're ready. Understanding first, speed later.
Challenge — 10 levels
10 questions per level, all correct to pass. Level 1 gives you 120 seconds; level 10 gives just 20. Optional speed goal for confident learners.
Mistake review
Wrong answers quietly collect in a mistake book. Replay them until they're gone — Tangyuan celebrates every one you clear.

Tangyuan Math is made for learners who already know their times tables and are ready for the next step: multiplying bigger numbers with confidence.
- Families practicing at home
- Homeschool parents looking for gentle drills
