Free math game for kids

My 8-year-old was struggling with times tables last year. I tried a bunch of math apps but they were either full of ads, required accounts, or let kids just guess without understanding what they're doing. So I built NumWiz: a Progressive Web App that practices all 4 basic operations (addition, subtraction, multiplication, division) and requires kids to show their reasoning step by step. What makes it different: Kids can't just guess the answer: they need to show HOW they got there Works offline (installable PWA) 3 languages: English, Polish, Spanish No accounts, no ads, no tracking Completely free I also wrote a blog with practical guides for parents: how to teach times tables, bridging through tens, teaching division, etc. 🎮 https://numwiz.net 📝 Blog: https://numwiz.net/blog/
