LEGO enthusiasts young and old will love this series of builder sets. The Master Builder Academy encourages kids to keep creating after they've put together the original models. Little space commanders will receive one new LEGO space figure, a brick separator and a storage box. After he's finished building the three main space vehicles, he'll have a whole wealth of ideas, cool tips, and even some video guides to help him discover fresh and fun new ways to keep his LEGO set alive long after the space vehicles have been broken down. Playing with LEGOs not only cultivates creativity, it also helps kids learn to think outside the box and gives them the chance to build skills in engineering and physics. (LEGO, $47.46)
