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 – there's nothing to pick from a list. • 18 practice sets aligned with the grade 1–4 curriculum, from addition and subtraction up to 20 through the times tables 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. For grades 1 to 4, aligned with the curriculum: Grade 1: Addition & subtraction up to 10 and up to 20 (with and without carrying) Grade 2: Addition & subtraction up to 100, small times tables (2/5/10), division Grade 3: Full times tables, full division, addition/subtraction up to 1000, semi-written calculation Grade 4: Large times tables, division with remainder, mental math with large numbers, mixed basic operations Privacy and fairness: Math Hero works completely offline, with no login and no account.
