I can’t think of any toy that lends itself more completely toward the teaching of STEM subjects (science, technology, engineering, and math) than LEGO® bricks. Everyone is looking for more ways to teach STEM these days, why not try LEGO STEM? You can do this — and you will be the hero of your school day with these inspired LEGO STEM activities to inspire your kids. I’ve even added LEGO STEAM with art activities to the list.
This huge list of brain-powered LEGO play is organized into categories to help you find what you are looking for super fast. In the years since I originally wrote this post, so much more is available now for each category, because STEM was just becoming a focus area and STEAM hadn’t even been conceived.
Now here we are in 2021 and the importance of science, technology, engineering, art, and math is getting more attention. This is good for us because more awesome bloggers are writing LEGO STEM posts!
Legos lend themselves to learning in so many ways. One of my favorite lessons I’ve ever taught using Lego bricks was actually an art class. When you add art to LEGO STEM you get LEGO STEAM. Art takes all of the other subjects and gives them wings and breath and energy. Creating art does good things to our brains and helps make all of the other brainy subjects more accessible. Therefore, I’ve included LEGO Art ideas on this list.

Hi – Trying to pin this posting, and I’m getting an error message: “Sorry, this site doesn’t allow you to save pins.” Is this intentional?
Thanks,
Pam
No – you are absolutely allowed to save pins. This glitch was caused a few weeks ago with a WordPress update and I have let both my host and Pinterest know but so far no updated patch has been released. I know my blog is not the only one experiencing problems, and at this point, sadly, there is nothing I can do about it. 🙁 Here is a pin of it you can repin: https://www.pinterest.com/pin/ARDcsEWpggmXeoxnBsncz1cD5QqJuiCNGzW15O0B-uonErjYmK9BYXw/
Great ideas for lego development. Thanks for these interesting ideas which are useful for my toddlers to build their own projects.
