Brain Is A Muscle: Exploring Your Fixed vs. Growth Mindset

Welcome everyone! Today we’ll dive into how your brain is like a muscle—you can strengthen it with effort. Introduce the title and objectives.

Fixed vs. Growth Mindset

• Fixed Mindset:
– Belief that talents and intelligence are static
– “I either can do it or I can’t.”

• Growth Mindset:
– Belief that abilities develop through effort and strategies
– “I haven’t mastered it yet.”

Define the two mindsets. Ask students to give examples from their own experience.

Growth Mindset in Action

• Thomas Edison: turned failures into learning steps
• J.K. Rowling: persisted after multiple rejections
• Your Turn: Name someone (or yourself) who improved through perseverance.

Share the Thomas Edison story: 1,000 failed attempts before creating a working light bulb. Invite a quick student example of someone who improved over time.

Think-Pair-Share: Spot the Mindset

Read each statement. Decide: Fixed or Growth?

  1. “I’m just not good at math.”
  2. “I enjoy challenges even when they’re hard.”
  3. “If I fail, I’m a failure.”
  4. “Mistakes help me learn.”

Explain Think-Pair-Share: students think individually, discuss with a partner, then we debrief as a class.

Myth or Fact?

We’ll sort statements into “Myth” or “Fact.”

Myth Examples:
• “Only natural geniuses succeed.”
• “You either have it or you don’t.”

Fact Examples:
• “Effort and good strategies improve skills.”
• “Struggling builds stronger brains.”

Introduce the card sort game. Explain that myths hold us back, while facts support growth.

Reframe Your Self-Talk

Negative Thought:
• “I’ll never understand this.”

Growth Reframe:
• “I can’t understand this yet, but I can try a new approach.”

Now you: Pick two negative thoughts and reframe them.

Model reframing the first negative thought on the board. Then direct students to their Reframe That Thought Sheet.

Next Steps: Mindset Pledge

Reflect and Write:
• What challenge will you tackle this week with a growth mindset?
• Make a personal promise to yourself.

Encourage students to set a real goal for the week. Remind them they’ll share this on their Mindset Pledge Reflection.

Game

Myth or Fact Mindset Cards

Use these 12 cards to play the card sort game. Students will decide whether each statement is a Myth (limiting belief) or a Fact (growth mindset truth). Print and cut each card. Distribute cards to pairs and have them sort into "Myth" or "Fact" piles, discussing their reasoning.

Cards:

Myths:

  1. "Only natural geniuses succeed."
  2. "You either have it or you don’t."
  3. "Making mistakes means you’re bad at something."
  4. "Intelligence is fixed at birth."
  5. "If it’s hard, you’re not good at it."
  6. "People are either smart or they’re not."

Facts:
7. "Effort and good strategies improve skills."
8. "Struggling builds stronger brains."
9. "Learning from mistakes helps us grow."
10. "Challenges push you to learn."
11. "Practice leads to improvement."
12. "Intelligence can be developed over time."
