Toddler activities / classes / skill development

Hi everyone,

Since schools are closed but extra after school actives are still on, I’m looking for recommendations to keep my 2 and half year old busy while he also develops some skills.

Please suggest some good classes for Karate / Gymnastics / Dance / Sports

No art and craft suggestions for now. He doesn’t sit at one place longer and is not keen on using pen paper at the moment.

Thank you :)
