Okay kiddo, so step dancing is a type of dancing where you use your feet to make really cool sounds and movements! It's also sometimes called "Irish dancing" because it's very popular in Ireland.
When you step dance, you wear special shoes that have hard bottoms called taps. These taps make noise when you hit them on the ground!
You also need to have really good rhythm and timing, because step dancing is all about making a beat with your feet. Sometimes people even dance together in groups and create awesome patterns and rhythms.
Step dancing is super cool because it combines music and dance in a really unique way. Plus, it's a great way to stay active and have fun!
