Activities with chromebooks
These sites use blocks of code, they are useful for those wanting to get started with coding. Most have tutorials and graded levels of activities as well as allowing freedom to experiment. All are free but some have paid upgrades.Scratch Jnr Chromebook app but it doesn't seem to work on all Chromebooks. Worth a try for younger students though. Lots more coding and computational thinking resources can be found on my Digital technologies curriculum site and many of those options will work on a Chromebook.
Hour of Code is a coding event designed to introduce students to computer science and coding. There are several sites that have hour of code activities and although Hour of Code takes place in December most activities are available all year round. Here are some Hour of Code sites:
Quizzes & Gameshows
Quizzlet - good for revision or language learning
Kahoot - to play - to create a Kahoot - fun game show format
Quizziz - Similar to Kahoot but students don't need to all play at the same time.
KnowledgeHook - A gameshow similar to Kahoot but has a few more options including a non-timed version. Students play here.
