You don’t need a fancy science kit to bring STEM learning to life. Sometimes, all it takes is a sunny day, a spark of imagination, and a pile of Biggo Blocks. These jumbo building blocks aren’t just for stacking—they’re a gateway to creativity, engineering, and hands-on discovery. Whether you’ve got a curious preschooler or a wildly inventive grade-schooler, Biggo Blocks turn your backyard into a STEM-powered play zone.

Here are five favorite Biggo builds that blend fun, movement, and learning—all while getting kids outside and off screens.

1. The Backyard Castle

Who says fairy tales can’t teach STEM? Gather your jumbo blocks and help your kids design their own backyard castle. Whether it’s tall turrets, strong gates, or arched doorways, this project gives kids the freedom to experiment with structure and stability.

Watch them problem-solve when their walls tip or their towers lean. Should they add a wider base? Use taller pieces in the middle? This kind of play is rich in STEM learning and loaded with storytelling opportunities. Bonus points if dragons or princesses show up.

STEM Sparks: Structure, symmetry, balance, and design thinking.

2. The Tower Challenge

Kids playing in the backyard building a tall tower out of jumbo blocks from Biggo Blocks.

Set a timer or make it a competition: who can build the tallest tower without it toppling over? Kids naturally explore gravity, weight distribution, and cause and effect through trial and error. Sometimes it works, sometimes it wobbles, and that’s exactly the point.

The taller the build, the more fun (and funny) it becomes. Expect giggles, frustration, and a whole lot of science in action.

STEM Sparks: Gravity, engineering, critical thinking, and resilience.

3. DIY Obstacle Course

This one’s perfect for the kid who never stops moving. Create an obstacle course using extra large building blocks as tunnels to crawl through, walls to jump over, or winding paths to run. Let your kids map it out, test it, and improve it.

It’s great for building gross motor skills—and even better for burning off that post-lunch energy. Plus, setting up the course encourages sequencing and planning, key parts of early STEM thinking.

STEM Sparks: Coordination, sequencing, problem-solving, and physical logic.

4. Build a Backyard Dragon or Dinosaur

Want to get kids excited about design? Try building a dinosaur or dragon using your Biggo Blocks. Wings, tails, spikes, and all—this is a creative challenge that lets kids think in 3D.

They’ll practice spatial awareness and design as they figure out how to bring their creature to life. Encourage them to name their creation, tell a story about it, and even build a habitat around it.

STEM Sparks: Spatial thinking, geometry, creative design, and teamwork.

5. Tea Party Table

Let’s turn those blocks into something practical. Help your kids create an outdoor table using Biggo Blocks—then add chairs, a tablecloth, and tiny snacks. Whether it becomes a tea party table, a pretend restaurant, or a lemonade stand, it’s a lesson in real-world construction.

Kids will think about size, height, and strength as they test out what works. This one’s great for role play and imaginative learning.

STEM Sparks: Real-world engineering, functional design, measurement, and pretend play.

Big Blocks, Bigger Learning

Here’s the thing: when kids play with Biggo Blocks, they’re not just passing time. They’re experimenting, thinking, and problem-solving—with their hands and their hearts. Each build comes with its own “aha!” moments and its own set of STEM lessons.

So whether they’re building a castle, racing through a maze, or hosting a tea party, they’re learning skills that stick. That’s the power of Biggo Blocks.
