We don't have any suitable devices so things like osmo and various robots I've seen on Amazon are out.
I do quite like the look of that mouse thing that I've seen mentioned a lot. But not sure if it's too babyish really. The DCs are quite young for their age (8/10, ASD possible LDs too) but it may be pushing it a bit. But from what I've found so far there doesn't seem to be much between things like that and complicated stuff like microbits, raspberry pi etc which I don't think they're ready for (complete beginners)
Any thoughts appreciated! :)
