Lesson Plan

Idea Generation Workshop Guide

Students will generate at least 15 ideas using two brainstorming techniques and select their top three using a criteria matrix.

This lesson is important because effective idea generation and selection are critical skills for problem-solving, innovation, and creative thinking in academic, professional, and personal contexts. Learning to diverge and converge ideas empowers students to approach challenges with confidence and make informed decisions.

Prep

Preparation Steps

15 minutes

Step 1

Warm Up: 60-Second Quantity Challenge

5 minutes

  • Objective: Activate prior knowledge and set a divergent thinking mindset.
    * Activity: Display a simple, open-ended prompt (e.g., "Ways to use a paperclip," "Things you can do with an old T-shirt"). Give students 60 seconds to write down as many ideas as possible individually.
    * Discussion: Ask students to share a few ideas. Emphasize the goal was quantity, not quality, introducing the concept of divergent thinking. (Slides 1-2 of Idea Storm Slides)

Step 2

Mini-Lesson: Brainstorming Rules & Criteria Matrices

10 minutes

  • Objective: Introduce key concepts of divergent and convergent thinking, and tools for each.
    * Instruction: Using the Idea Storm Slides (Slides 3-7), explain:
    * Divergent Thinking: Generating many ideas, no judgment, wild ideas welcome.
    * Convergent Thinking: Evaluating and selecting the best ideas.
    * Brainstorming Techniques: Briefly introduce Round Robin Brainstorm and Crazy 8s Sprint as methods for divergent thinking.
    * Criteria Matrices: Explain their purpose for structured evaluation (convergent thinking), using the Idea Matrix Selector Worksheet as an example. Discuss how to define criteria and score ideas.

Step 3

Practice: Idea Generation Techniques

10 minutes

  • Objective: Apply brainstorming techniques to generate a high quantity of ideas.
    * Activity 1: Round Robin Brainstorm (5 minutes): Divide students into small groups (3-4). Present a challenge (e.g., "How can we make our school more eco-friendly?"). Follow instructions on Round Robin Brainstorm Activity. Encourage students to aim for 15+ ideas across both activities.
    * Activity 2: Crazy 8s Sprint (5 minutes): Transition to individual or pair work. Provide each student/pair with paper folded into 8 sections. Present a new challenge or continue the previous one. Follow instructions on Crazy 8s Sprint Game.

Step 4

Converge & Reflect: Select Top Ideas

5 minutes

  • Objective: Students will apply convergent thinking to select their best ideas.
    * Activity: Distribute the Idea Matrix Selector Worksheet. Instruct students to transfer their top 5-7 ideas from the brainstorming activities to the worksheet. Guide them through defining 2-3 criteria and scoring their ideas to select their top three.
    * Cool Down/Exit Ticket: Have students complete the Top Three Idea Record Cool Down, explaining their rationale for their top three choices. Collect for assessment of understanding. (Slides 8-9 of Idea Storm Slides)

Slide Deck

Welcome to Idea Storm!

Are you ready to unlock your creative potential and become an idea champion?

Welcome students and introduce the lesson's exciting topic: becoming idea champions! Start with a quick engagement question.

Warm-Up: The Quantity Challenge

Your Mission: In 60 seconds, list as many uses for a common object (e.g., a brick, a paperclip, an old shoe).

Rule #1: No Bad Ideas! Write down EVERYTHING that comes to mind.

Explain the warm-up activity. Emphasize that for this activity, quantity is king โ€“ no bad ideas! The goal is to generate as many diverse ideas as possible within the time limit.

Divergent Thinking: Go Wide!

๐Ÿ’ก What is it? Thinking broadly to generate many different ideas.
๐Ÿง  The Goal: Quantity over quality at this stage.
๐Ÿšซ The Rule: Suspend judgment. All ideas are welcome, even the wild ones!

Introduce Divergent Thinking. Explain it's about expanding possibilities. Use a simple analogy, like a flashlight beam widening to explore a dark room.

Convergent Thinking: Focus In!

๐ŸŽฏ What is it? Evaluating and selecting the best ideas from your pool.
โœ… The Goal: Choose the most viable, creative, or effective solutions.
๐Ÿค” The Rule: Use criteria to make informed decisions.

Introduce Convergent Thinking. Explain it's about narrowing down and focusing. Use an analogy like a funnel, where many ideas go in and a few refined ones come out.

Divergent Tools: Brainstorming Techniques

We'll explore two powerful techniques:
1. Round Robin Brainstorm: Build on each other's ideas!
2. Crazy 8s Sprint: Rapid-fire individual idea generation!

Briefly introduce the brainstorming techniques they'll use today. Mention they are tools for divergent thinking.

Convergent Tools: Criteria Matrix

๐Ÿ“Š What is it? A structured way to evaluate ideas based on specific criteria.
๐ŸŒŸ Why use it? Helps you make objective decisions, not just pick favorites.
๐Ÿง  How it works: List your ideas, list your criteria, then score each idea against each criterion.

Explain the importance of criteria matrices for convergent thinking. Highlight that this tool helps them be objective.

Time to Generate Ideas!

Get ready to dive into the world of divergent thinking. Let the ideas flow!

Transition to the practice activities. Remind them to embrace divergent thinking in the next phase.

Now, Let's Converge!

It's time to put on your critical thinking hats and use your Idea Matrix Selector Worksheet to narrow down your fantastic ideas.

Explain that now they will shift from generating to evaluating. Emphasize using the matrix.

Reflect & Share Your Top Three

Complete your Top Three Idea Record Cool Down. What did you learn about your own creative process today?

Wrap up the lesson, reminding them of the power of both divergent and convergent thinking. Assign the cool-down.

Activity

Round Robin Brainstorm Activity

Objective: Generate a wide variety of ideas by building upon each other's thoughts.

Time: 5 minutes

Instructions:

  1. Form Groups: Get into groups of 3-4 students.
  2. Define the Challenge: Your teacher will present a challenge or problem statement. (e.g., "How can we reduce food waste in our school cafeteria?")
  3. Start Writing: Each student will silently write down one idea on a piece of paper related to the challenge.
  4. Pass and Add: After 30 seconds, pass your paper to the person on your right.
  5. Build or New: When you receive a paper, read the idea(s) on it. You can either:
    • Add a new idea that builds on what's already there (e.g., make it more specific, add a new angle).
    • Write a completely new idea if you can't think of a way to build on the existing one.
  6. Keep Passing: Continue passing the papers and adding ideas for about 4 minutes. Focus on quantity and diverse thinking!
  7. Review: When time is called, review the papers in your group. You should have many ideas generated collectively!
