Unless teaching programming or some web design work is taking a huge amount of time each week, there's no reason cooking or first-aid can't be taught as well. However, cooking is one thing that is not likely to be taught; the use of knives or even a single shared oven is a disaster waiting to happen, at least according to my brother (he's a primary school teacher).

My main concern would be having the teachers trained to be able to provide such an education themselves. Often primary school teachers tend to be older and female; for whatever reasons, this is not a demographic that would be particularly capable of learning 'enough' programming to teach it effectively, even at a primary school level.

However, as an Estonian citizen I think it's pretty cool idea. There is a big push here to make the country IT-focused, so it's no surprise this filters down to the lower levels of education.
