I'm planning to buying a Chromebook for my child, but before I buy it, I wanted to confirm that Scratch would work on it and that the Lego Wedo blocks would work on it as well.

Thanks.

I have a chromebook pixel, and the software for the plugins are only supported on MacOS or WindowsOS. Sorry.

My browser / operating system: ChromeOS 5841.98.0, Chrome 36.0.1985.143, Flash 14.0 (release 0)

Scratch would work, but not the lego wedo blocks.

lego wedo does not work on chromebooks because you need to download a plugin but chrome books can only download things if its from the chrome web store
