Tally Turtle

Start with number bonds to ten and work your way to fractions, decimals and ratios with Tally, a friendly turtle from the Luo River, in a Chinese garden. Practice in English or Simplified Chinese. Choose a suggested grade or take a short placement exercise to find a starting point. • Explore 58 arithmetic skills. The skill tree shows which ideas build on each other and where to practice next. • Enter written calculations one digit at a time. Follow hints for regrouping, partial products, quotients and remainders. • Revisit missed problems, earn skill stars and track your progress through daily goals and practice records. • A dot on Tally’s shell lights up as you fill in a correct digit. Music and petals build with your combo. After the round, explore a Luo Shu square and see why three numbers along any line add to 15. Adjust sound, motion and haptics separately. • On iPhone Duo, practice with a sidebar on the folded display. Unfold to see the worksheet and keypad side by side. Your current problem and entered digits carry over. Grades 1–3 include 28 free skills. One optional in-app purchase unlocks all 30 skills in Grades 4–6. Restore Purchases is available. The suggested grades follow a shared arithmetic progression drawn from several school systems. Local teaching sequences can vary. Practice and review work on your device, where your learning records stay. Apple handles purchases and restores. No app account is needed, and Tally Turtle has no ads. When grades 4–6 are locked, open Grades 4–6 Course Pack on Home to buy them. To restore a previous purchase, open Settings, choose Courses & Purchases, complete the parent check and tap Restore purchases. Home shows Full Edition once all six grades are unlocked.
