It is about introducing and practising coding through stories we read or learn about at school or in kindergarten. It can be done without computers, with robots or coding apps. An example: I use Happy House and Happy Street course books in primary school to teach English. They have their own stories with the Happy Families and the Colin stories but we also work with stories like Gruffalo, Winnie the Witch, etc. Coding these stories as a whole class or in groups or pair work would make kids much more motivated to learn, not to mention the additional benefits they could gain with it.
