Math Hero – Mental Math 1-4

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.
