Math Hero turns daily mental math practice into a motivating experience for elementary school kids – no multiple choice, just real calculating, visible progress, and a colorful, kid-friendly design. Why Math Hero?: • Real mental math, not guessing: answers are entered on a number pad or by hand – there's nothing to pick from a list. • Over 60 practice sets aligned with the grade 1–4 curriculum, from addition and subtraction up to 20 through every single times table to division with remainder and mixed operations. • Visible progress instead of sticker charts: personal best times, animated gold/silver/bronze trophies for new records, and a progress chart tracking time and mistakes across every session. • A learning log with the full practice history, grouped by date. • Multiple profiles on one device – perfect for siblings. • Fair on every question: only one mistake counts per problem, however many tries it takes to get there. • Sound effects for right/wrong answers and new records, with a mute switch. How it works: Choose a profile → choose a grade → choose a training → solve 20 problems → see your time and mistakes, and celebrate a new record if you get one. Ready for the next round.
