Your students already know Jimothy from The Jimothy Test. This lesson flips their role. Instead of checking content, they create it.

Students write a precise design brief for a 3D-printable version of Jimothy using the WISH framework (Who it's for, Information, Shape, How much). The teacher runs that prompt live on one projected screen, and the class watches an AI write and run code to build the shape. Then they do the part that matters most: they check the result against their goal and improve the prompt.

The lesson isn't really about raccoons or 3D printers. It's about prompting as a skill. A vague prompt gets a vague result. A specific prompt, with real measurements and real details, gets something close to what you pictured.

What's inside:

• Teacher guide with a 45-minute, minute-by-minute lesson flow

• Setup checklist for before class

• The WISH Check printable poster (Prompt framework)

• Weak vs. strong prompt reference with a ready-to-use example prompt

• Student prompt-writing worksheet

• Iteration log to compare v1, v2, and v3

• Debrief guide with discussion questions and listen-fors

• Facilitation guide and prompt rubric

• Troubleshooting and data privacy notes

  
  

Details:

• Grades 6-8, 45 minutes

• Whole class, one computer, no student accounts required

• Works with Claude, ChatGPT, Gemini or other LLMs that produce code

• Aligned to ISTE Standards for Students 1.4 (Innovative Designer) and AI4K12 Big Idea #4 (Natural Interaction)

• 
  

Pairs naturally with The Jimothy Test for a verify-then-create arc: first students learn to check what AI produces, then they learn to direct it.
