How to Encourage Co-Building With Siblings

Sibling relationships can be full of love, laughter… and the occasional clash over who gets the last cookie or the top bunk. But when it comes to play, there’s one secret weapon that can help channel all that energy into something constructive: co-building with large building blocks.

Whether your kids are naturally close or need a little nudge to collaborate, jumbo blocks like Biggo Blocks offer the perfect opportunity to teach teamwork, communication, and problem-solving—all while having fun.

Here’s how to set the stage for sibling cooperation and creative success:

1. Set a Shared Goal

Instead of letting kids dive into separate projects, start with a unified mission. This could be something as simple as:

Building a robot friend taller than they are
Designing a fantasy castle with secret rooms
Creating a garage for their toy cars
Constructing a maze for their stuffed animals

Extra large building blocks are especially great for these kinds of projects because they make big builds achievable and exciting. When the end result feels like a team win, kids are more motivated to work with each other, not against.

2. Assign Creative Roles

When everyone wants to be the boss, assigning roles can prevent squabbles and encourage collaboration. Try rotating these roles every 10–15 minutes:

Builder – Stacks the blocks and follows the design
Designer – Decides what it looks like and picks block colors
Tester – Makes sure it’s sturdy, functional, or “cool enough”

This keeps things balanced and gives each sibling a chance to lead, follow, and problem-solve together. It also teaches empathy—kids begin to appreciate the work behind each role.

3. Use Timed Challenges

Add a layer of fun and structure with build challenges. Set a timer and prompt them with questions like:

“Can you work together to build a rocket in 20 minutes?”
“How fast can you make a bridge that holds a teddy bear?”
“Can you switch roles and finish the build in time?”

Jumbo blocks make this kind of active, fast-paced play possible. They’re easy to grip, stack, and adjust, perfect for cooperative building games that feel like play but teach like a classroom.

4. Turn Disagreements Into Learning Moments

Arguments will happen. One sibling wants to build a spaceship, the other wants a castle. This is a great chance to practice conflict resolution and emotional intelligence. Ask questions like:

“What if we built a space castle?”
“Can you take turns choosing what comes next?”
“What can we do to make sure both of your ideas get included?”

Helping kids find a middle ground reinforces respect, listening, and compromise—life skills that go far beyond the playroom.

5. Celebrate the Final Creation Together

Once their co-built masterpiece is done, don’t just clean it up, celebrate it!

Snap a photo and display it on the fridge
Let the build stay up for a few days as “block art”
Share it with extended family or friends
Post it in the BiggoBlocks Facebook Community (and tag #BiggoBlocks!)

Recognition boosts confidence and gives siblings a sense of pride in what they created together. It also encourages them to team up again for the next build.

6. Make Co-Building a Regular Routine

The more often kids co-build, the better they get at working together. Set aside a specific co-building time during the week after school, weekend mornings, or screen-free evenings.

Switch up the instructions and goals regularly to keep things fresh. Keep your jumbo blocks easily accessible and ready for action. A large bin or low shelf works great for encouraging spontaneous team play.

Why It Works

When kids build together, something special happens. They talk, listen, and make decisions as a team. They work toward a common goal and learn to compromise.

Each block they stack becomes a lesson in patience, cooperation, and creativity. And with large building blocks, those lessons are larger than life. These big pieces make it easy to share, switch roles, and physically work together side-by-side. They naturally encourage teamwork. And when siblings succeed together, they don’t just build structures, they build stronger bonds.
