The Benefits of LEGO

LEGO building has a lot of benefits for kids of all ages. Not only does it help kids build spatial awareness skills and develop the basics of engineering and design, it’s also a wonderful creative outlet, too!

“Getting very involved deeply involved in a creative task can be great for well-being, mindfulness, relaxation.”

 Carrie Barron, Director of Creativity for Resilience at Dell Medical School

Easy LEGO Buildings to Make with Bricks You Already Own

If you have a bunch of LEGO bricks at home, it’s fun to build the original set, but there isn’t much creativity in that. Also, if you lose the instructions or some of the pieces, then it becomes annoying to try and build that set again.

You have to order individual pieces or have them 3D printed (but if you’re curious, learn How to Make a Lego Brick Using a 3D Printer here!), you have to track down the instructions- it’s a whole big thing.

Instead, why not follow along with these easy LEGO buildings and use LEGO pieces that you already own to create new and fun LEGO building ideas!

These LEGO sets are perfect for doing STEM activities and creating LEGO structures and easy LEGO buildings.
