## What is Trachtenberg Kids?

Trachtenberg Kids turns multiplication into a superpower. Using the famous Trachtenberg system — the "speed math" once taught to engineers — your child learns to multiply big numbers in their head, no calculator needed.

Every lesson reveals a secret, walks your child through it step by step, then builds confidence with guided practice, free play, and a 60-second Speed Round. Friendly mascots and a "Show Off" mode keep them coming back.

WHAT YOUR CHILD LEARNS
  • ×11 and ×12
  • The halving family: ×5, ×6, ×7
  • The complement family: ×9, ×8, ×4, ×3
  • How to multiply 2-digit numbers in their head, left to right

HOW IT WORKS
  • Watch the trick revealed with a fun animation
  • Practice with step-by-step hints, then solo
  • Beat the clock and build a streak
  • Earn stars and unlock the next trick

MADE FOR FAMILIES
  • One family account, a profile per kid — progress syncs across devices
  • A grown-up area protected by a parent PIN
  • No ads. No chat. No tracking.

FREE & PREMIUM
The ×11 trick is free. Unlock every trick with Trachtenberg Kids Premium — an auto-renewable subscription. It renews automatically unless cancelled at least 24 hours before the period ends; manage or cancel anytime in Settings > Apple ID > Subscriptions.
