TedQu Pi

TedQu Pi teaches the Soroban abacus the way it is taught in class — one formula at a time, with the beads in your child's hands and a little practice every day. Eight levels take a learner from their first bead to mental arithmetic. Each level follows the same rhythm: learn the technique, practise it until it is comfortable, then prove it against the clock. WHAT'S INSIDE • The Journey — eight levels of Soroban technique, in the order a class teaches them • Guided lessons — each new formula explained step by step, with the beads guided as your child follows along • Daily drill — ten fresh problems at your child's own level, with instant feedback and nothing recorded • Challenge — a timed run that turns technique into speed, and shows exactly which sums to look at again • Free Mode — the whole thirteen-rod instrument, to set and explore with no exercise attached • Stars, badges and streaks that mark every level cleared BUILT FOR HOW CHILDREN ACTUALLY PRACTISE Work is saved on the device and syncs when the connection comes back, so a drill finished in the car still counts. A missed sum can be replayed bead by bead, so a child sees the move they got wrong rather than just a red cross. FOR PARENTS A PIN-protected parent area shows what your child has covered, where they are in the ladder, and how long they have been practising. Daily screen-time limits are yours to set, and progress reports can be saved or shared. FOR SCHOOLS Teachers get a class roster, per-student progress and the levels each child has reached, can set the week's work, and can send a practice reminder home. Admins manage classes and students. SIGNING IN Accounts are provided by your school. Sign in with the phone number or email your school has registered — there is no public sign-up. NO ADS, NO PURCHASES No advertising, no in-app purchases, and no third-party tracking. Your child's data is used to run the lessons and to show progress to their parent and teacher, nothing else.
