3 Classroom Brainstorming Strategies To Unlock More Ideas

We tend to picture brainstorming as a fast, energetic moment. Students calling out ideas, sticky notes filling the wall, creativity happening in real time.

But in practice, that version of classroom brainstorming doesn’t always work for every student.

Some students hang back.
Some ideas never get said out loud.
And too often, the “best” idea shows up too early — ending the thinking before it really begins.

Classroom brainstorming isn’t just about generating ideas; it’s about creating a space where ideas can grow.

A space where…
Students’ ideas build on each other instead of competing.
Quieter voices contribute.
And unexpected ideas (the kind that lead to real innovation) have room to surface.

Here are three simple ways to make that happen in your classroom:

1. Group Brainstorming: Create a “Yes, And…” Culture

In the writers’ room for hit shows like Grey’s Anatomy, Shonda Rhimes, the award-winning producer, screenwriter, director, and author, doesn’t rely on one perfect idea. Instead, ideas are built together—one suggestion becoming the starting point for the next.

A writer might pitch a twist. Another adds to it. Someone else pushes it further.

That’s the power of “Yes, and…”—it keeps ideas moving.

Borrowed from improvisational theater, the “Yes, and…” technique encourages students to build on each other’s ideas rather than critique them.

Example:

Student 1: I think customers want an inexpensive option.

Student 2: Yes, and it should be easy to deliver.

Student 3: Yes, and it should come in both pink and green. 

This approach keeps momentum moving and reinforces that innovation is collaborative.

2. Use Brainwriting for Inclusive Participation

Before founding Spanx, Sara Blakely had an idea she almost didn’t share. It felt too simple. Too different. That idea, cutting the feet off pantyhose, became the foundation of a billion-dollar company.

Traditional brainstorming often favors the loudest voices in the room. Brainwriting levels the playing field.

The process:

• Each student writes three ideas on a sheet of paper.

• Papers are passed to another student.

• The next student builds on those ideas.

Pro Tip: Have students record ideas in different ways (writing and drawing on big pieces of paper, with markers and gel pens) anything to step out of the regular notetaking process. 

This approach is particularly effective for ensuring thatall voices— especially those of girls and young women who might otherwise be overshadowed — are centered and heard.

3. Encourage Perspective Shifting (Role-Playing)

Coco Chanel changed fashion by asking a different question. Instead of designing what was expected, she imagined what clothing would look like if it were designed for comfort and freedom.

That shift in perspective led to designs that redefined how women dressed.

Students often struggle to propose bold ideas because they feel constrained by expectations.

Role-playing can help break that barrier.

Ask students to generate ideas from a different perspective:

• A superhero solving the problem

• A frustrated customer

• The CEO of a major company

Changing perspectives makes it easier for students to suggest unconventional solutions — and often leads to more creative outcomes.

Educators Ask: What should I tell my students when they are stuck?

It’s hard when your students are stuck. Your instinct is to be helpful and provide a spark, but the goal of divergent thinking is for them to generate those sparks themselves. Here’s what we suggest:

Start with the Mindset

• Normalize “The Wall”: Remind students that hitting a wall isn’t a sign of failure; it’s a sign that they’ve cleared out the obvious ideas and are now entering the “innovation zone.”

• Be Patient: Give them the space to feel a little uncomfortable.

Try These Prompts

Instead of giving an answer, ask a question that shifts their perspective:

The Impossible: “What is an idea that seems completely impossible?”

The Maverick: “What is an answer that no one else in this room would suggest?”

The Mash-up: “What would happen if we combined two of your ideas together?”

The Persona: “Imagine you are a (superhero, frustrated customer, or a CEO). How might they solve this?”

The Magic Wand: “What if we had unlimited money, more time, or help from an expert?”

The Deep Dive: “Tell me more about [repeat a detail the student shared].”

The “30-Second Rule”

After offering one of these prompts, walk away. This removes the pressure of an immediate “performance” for you. It gives the student 30 seconds of quiet, low-stakes processing time to let the new perspective take root.

Teaching Brainstorming as a Skill

Brainstorming isn’t about having the best idea first. It’s about creating space for ideas to grow.

When students build on each other, share freely, and explore new perspectives, they don’t just generate better ideas; they start to see themselves as creative thinkers.

And that’s a skill they’ll carry far beyond the classroom.
