# Math for Kids

Welcome to Math for Kids! Math can be fun, honest!
If you don't believe us, take a look around this site!

On this site you will find ideas for activities, puzzles, games, recommendations for apps and websites, and short videos. All of these have something to do with mathematics. You can play around with them at home, either on your own or with your parents, making for an exciting, fun, challenging and creative experience.
Since a lot of school children now have to stay at home, we decided to put this website together. The site will grow bit by bit and we will keep adding to it, so it is always worth keeping a look out for new activities. This is a service from the mathematical exhibition ix-quadrat from the Technical University of Munich together with the research group for geometry and visualization and science-to-touch.com
