Prototype Sprint
Plan just enough to build safely and clearly — then spend the majority of the lesson making something you can test.
Too little
A sketch only, when the key function needs physical testing.
Enough
A physical model that lets a user try the important interaction, fit, sequence, support, or organization feature.
Main form, labels, key dimensions/details.
Materials + teacher-approved tools.
3–5 main making steps.
Which function must the prototype demonstrate?
Plan → build → quick function check.
Plan
Planning drawing + short sequence.
Build
Create the key structure / system representation.
Check
Try the core function once and list any change made.
Year 1 asks students to list changes made. Keep the record concise and accurate.
Function
Can one important action be tried?
User
Can another person understand what to do?
Criteria
Are the success criteria available?
Safe
Is the prototype suitable for peer testing?
Finish one sentence.
Next lesson
Students run a feedback carousel, make one required improvement, and retest the changed prototype.
