I found the resources and the unit on NPL very interesting with plenty of online tools and unplugged activities to engage students. I will be sharing many of these with my staff next year. I also found the site Maching Learning for KIds Uk excellent resourse and completed an activity https://machinelearningforkids.co.uk/#!/welcome

This was easy to create without making an account but class accounts are possible. Video here: https://www.youtube.com/watch?v=EjbHXMzeX4c

Another video I found suitable and engaging for young students…..especially if your students are familar with Linda Liukas (author of Hello Ruby ).
