LEGO Building Challenge for Kids: Brain Puzzles

LEGO® Brain Puzzles! This open-ended LEGO® building challenge is perfect for a LEGO® club, class, or group. Or even a family game night!

Challenge: Build a puzzle that makes a 10 x 10 square. The pieces can be any shape. See if others can solve your puzzle. If they solve it very quickly, change the shape of the pieces to create a more difficult puzzle!

The puzzle pieces are made out of basic bricks, with a layer of plates on top to attach them. They’re easy to build because you can just add whatever bricks you have!

I built the puzzle above. It took my husband several minutes to solve it, so I knew it was a good one! The interesting thing was that of all the boys, the one who solved this puzzle the fastest was my 6 year old. It’s so interesting to watch how kids approach these puzzles. Some naturally try the pieces in several different positions, while others get stuck thinking that a piece should go in one particular place. It’s a good exercise for the brain whether it’s something that comes naturally or not!

Tips and Ideas for Extending the Learning:

• Trace around the edges of the puzzle on paper so that the person solving it can see what the completed shape should be. Or build a LEGO® frame for your puzzle.
• What other puzzle shapes can you build besides squares?
• Explore – does your puzzle have more than one possible solution? (Be careful – what may appear to be another solution is just the same solution turned 90 degrees.) Do all puzzles have the same number of solutions?
