You can either use the online version at the website, or you can download and install the Scratch 2.0 Offline Editor. Scratch is developed by The Lifelong Kindergarten Group at the Massachusetts Institute of Technology, and is completely free to use. If it’s red, you need to install the browser plug-in. The yellow dot next to LEGO WeDo in the middle column indicates that the WeDo hub hasn’t yet been plugged into the computer. Scratch once the WeDo extension has been enabled.
I want to tell you about how I’ve been using Scratch and WeDo with children in the UK. Even better, Scratch has a built-in extension that allows it to work with LEGO’s WeDo robot kits. It’s a child-friendly system where you code by dragging around colored blocks and snapping them together – and for that reason some schools call it ‘Computer LEGO’. You may have heard of the computer programming language Scratch.
