Introducing your kids to coding early on is a wise idea. You don’t want to give them a thick C programming book on their first day though. Osmo Coding is a fun set that teaches logic skills and problem solving to your children. They will just have to snap physical blocks together to complete sequences of commands.
You are going to need an Osmo base and reflector to get started. Each block represents a different command, so your children can learn about coding in an interactive fashion.
