Lesson Procedure

1. Understand (Identify Problems)

• In groups, students brainstorm classroom problems without judgment.
  • Grade 2-3: Classroom problem
  • Grade 4: School problem
  • Grade 5: Any problem
• Write all ideas down.
• Select the top three problems and highlight them.
• As a group, choose one problem to focus on.

2. Define (Frame the Problem)

• Groups explain their chosen problem in detail.
• Discuss why this problem matters and why solving it would help the classroom.

3. Ideate (Generate Solutions)

• Brainstorm possible Dash accessory ideas that could solve the problem.
• No evaluating during brainstorming — just idea generation.
• Select the top three solutions and highlight them.
• Pick one solution to pursue further.
• Record details: how will it work? what will it look like?

4. Plan & Build (Prototype)

• Assign team roles (Documentarian, Builder, Programmer).
• Sketch the accessory design.
• Create a materials list.
• Build a prototype using classroom materials.

5. Test (Iterate & Improve)

• Program Dash to demonstrate the accessory in action.
• Run tests and note mistakes.
• Gather feedback from peers and teacher.
• Revise the design to improve functionality.
• Record results and reflect on what worked and what could be better.

Assessment

Use this Evaluation Rubric

• Programming:
  Students use coding concepts in Dash to bring their design to life. Proficiency is shown by completing tasks independently, with advanced solutions (efficient code, use of lights, sounds, sensors, loops) indicating exemplary work.

• Reflection & Documentation:
  Students record their design process using journals, sketches, or multimedia tools. Strong performance includes clear, thoughtful reflection using target vocabulary, and thorough documentation of each design phase.

• Collaboration & Communication:
  Students actively participate in group discussions, cooperate with peers, and contribute to presentations. High-level performance includes giving constructive feedback to others, incorporating peer feedback, and clearly communicating design ideas.

• Creativity:
  Students generate multiple solutions, apply the iterative process, and refine their ideas. Outstanding creativity is shown when students go beyond expected requirements, developing imaginative, original, and effective solutions.

Extension Ideas

• Host a “Design Expo” where groups present their prototypes to the class.
• Encourage students to document the process in video or photos.
• Challenge groups to refine their design further or combine ideas.
