We use Discovery Education/ Espresso Coding as our scheme for coding in school. Most of the children know the login details but they are USER: student19064 and PASSWORD: dragon.
This site https://hourofcode.com/uk/learn also has some fun coding activities.
Most of the children have been working through the levels on Light Bot too: https://lightbot.com/hour-of-code.html
Some children have also been trying to improve their typing skills. BBC Dance Mat Typing provides a fun way to work on this skill.
