These LEGO Challenge Ideas will make it easy to hold your own master building competition!

Are your kids aspiring master builders? Do they REALLY love LEGO bricks? If you’ve got kids that love amazing builds, they will have a blast competing in their own LEGO challenges.

There are lots of printable LEGO challenge ideas out there on the internet, but my goal with these was to create fun competitive challenges rather than just simple boredom busters. Oh, these will definitely work well for a boredom buster on a rainy day! But they’re also great challenges to do at a birthday party or with a LEGO club.

Do your kids love the LEGO Masters TV show? Hold your own competition with these printable LEGO challenge cards!

There are 20 printable LEGO Challenge Cards to print. Just print them and cut them apart. You may want to use card stock or laminate the cards for durability.

Each card is labeled with the topic so you can easily grab the one you want.

How to Use the LEGO Challenge Ideas

First, print the challenge cards with the link at the bottom of this post.

Then, gather your LEGO bricks! Kids may want to do some sorting before starting. It’s helpful if you put all the plates together (flat bricks) and sort out bricks that have studs on the side, joint pieces, wheels, windows, eyes, etc.

Next, choose teams and pick a challenge.

Then set a timer, and start building! Depending on the age of the kids, I would allow 1-2 hours for a true LEGO masters-style challenge. Teens may want even longer.

A big thanks to our real-life friends who allowed us to use the photos below! They celebrated a birthday with a family LEGO masters challenge – Fill a Plate with Food. Aren’t these projects brilliant? Thank you to Elijah and Enoch and your parents for sharing these awesome ideas with us.

These food builds were completed as a two hour challenge.

Finally, choose a winner!

You can decide on how to choose a winner based on the amount of participants and their ages. The family that did the food challenge above posted photos on Facebook and collected votes.

If you have a large class or group, you may want to have the kids vote on the winner.

Or, the parents/teachers can simply choose a winner.

Another option is to have each group give a presentation on their project, but not choose a winner. The fun of this activity is to be inspired by all the ideas that other people create!

Need LEGO Bricks? Grow Your Collection!

In order to build really epic LEGO projects, kids are going to have to have a good sized LEGO collection. There’s just no way around that. With all the specialized sets now, it can be hard to collect a bunch of random pieces if kids want to keep their sets together.

Here’s what I recommend for growing your collection of random bricks:

  • Purchase clearance sets just for the pieces – watch for sales at Target and Walmart, etc.
  • Watch Facebook buy/sell/trade groups. You can often find people selling gallon ziplock bags full of bricks, or random sets.
  • Check thrift stores and antique stores for used LEGO sets and bricks. Also check garage sales.
  • Buy loose bricks from the Brick Wall at the official LEGO Store.
  • Check to see if your area has any LEGO resale shops. We have a nice Bricks & Minifigs here locally!
  • Use Brick Link for ordering specific individual pieces that you really want to have. We use Brick Link all the time!

Here are sets we recommend:

Grab the LEGO Classic Large Creative Brick Box for $37.99, on sale from $59.99. That’s a good deal!

You can also get the LEGO Class Medium Creative Brick Box for $23.73. Both of these are a great place to start!

    I run a Lego Club at our church every Friday, we have over 40 children on the register.
    It’s wonderful to have some new ideas.
    Thank you for these cards.

    Legos are the most popular stem and play choice for my third graders. I wish they were a bit more economical. I am building our collection slowly.

    Love these ideas for my library LEGO club! I was very confused when I scrolled through and recognized those "plates of food". I just happen to be Elijah and Enoch's real-life aunt! What a coincidence that I stumbled across this article.

    Thank you very much for these ideas! I was out of ideas what new to do with LEGO bricks. I have pupils who are crazy about LEGOs and they only want to be scientists if I give them a LEGO challenge! Thanks!
