Rounding Unlocked

Rounding Unlocked teaches kids how to round numbers the right way — through understanding, not just memorization.

Built by a real educator with 20+ years of experience teaching in Philadelphia classrooms, this app takes children through 6 carefully sequenced worlds that build rounding fluency from the ground up.

What your child will learn:
- World 1: What is Rounding? (FREE)
- World 2: Rounding to the Nearest 10 (FREE)
- World 3: Rounding to the Nearest 100
- World 4: Rounding to the Nearest 1,000
- World 5: Rounding Decimals
- World 6: Estimating with Rounding

Each world includes a Learn mode with visual models and a Practice mode with 10 questions. Complete all 6 worlds and take the Rounding Master Challenge — 40 questions, timed, with a certificate of completion.

Worlds 1–2 are free. Unlock the full app for $2.99.
