20+ Simple Lego Engineering Challenges Kids Can Do Alone!

As kids, most of us spent hours building easy LEGO creations. You may have been using them to build sets from a boxed set, or perhaps you had a ton of different colored LEGO that you used to create whatever your mind could think up.

If you are looking for fun ways to get your kids to build more with LEGO, these LEGO engineering challenges can be a great place to start.

While they can certainly use these to get started, these are fun engineering activities that will get them excited about building.

Here are 20 LEGO engineering activities for your kids to do with LEGO bricks. Kids will want to try these LEGO projects again and again!

Simple Lego Engineering Challenges Kids Can Do Alone

While I like working with LEGO alongside my kids, I don’t like things that are beyond their personal skill level. I want my kids to explore and build using their own imagination, so we usually keep our LEGO creations a bit simplier than some.

I love using LEGO bricks as the basis for engineering projects, and LEGO really leans into this with their education line.
