Scratch (http://scratch.mit.edu/) is getting a lot of attention from teachers in the UK. The government recently scrapped the existing IT curriculum in schools and wants more programming taught in schools.

OK, HNers, here is something to chew on...
You have around 5 million children in schools between 5 and 11 years old. You have professional and well trained teachers but with variable skill sets, remember teachers teach everything to a single class in that age group. You have decent numbers of PCs/Laptops and some tablet use. The government wants all children to learn programming. What are you going to do?
