Free to try. One-time unlock — no subscriptions, no ads. Works offline. No data collected. Subtraction for Kids: Math helps children ages 6–8 learn to take away within 20 in a calm, playful way. Your child counts friendly objects, hops along a number line, solves number sentences and story problems, and traces the numbers 0–9 with the correct stroke order — all at their own pace, with gentle, encouraging feedback and never a timer or a score. What's inside: • Take Away — see subtraction come to life with objects you can tap • Count What's Left — pick-the-answer practice within 20 • Number Line Jumps — a clear, visual way to subtract • Number Sentences — build real math confidence • Missing Number — playful problem solving • Trace the Numbers — write 0–9 the right way • Story Problems — everyday subtraction to 20 Why parents love it: • No ads, no third-party tracking, no data collected — ever • Works completely offline • A parental gate protects every purchase and link • Kind by design: no timers, no scores, no pressure Free to download and try.
