If you haven't come across it before, then for younger builders who are new to LEGO, there is a range designed especially for them, and it's called LEGO Juniors.
I'm a fan of LEGO Juniors. I think it makes a great bridge between DUPLO and little LEGO. The components are all straightforward little standard LEGO pieces, and they are part of the other ranges, such as Knights, Princess, Batman and City, but if you were making a vehicle then you'd find a chassis piece to start you off, and instead of having to make a complex or large part, it will already be in one piece - as LEGO say 'Easy to Build'.
