Your activity / Right here
Bring a notebook. Begin below.
The activity is included on this page. Work on paper or in your own document; keep your first attempt and the evidence you checked.
Luna's Unplugged Break
Luna says: paws off the phone. No screens. A ruler or tape measure helps. About 15 minutes.
Measure something real and do math with it on paper. Choose one:
• Count your steps across a room. Measure one step, then estimate the room's length.
• Take a recipe and work out the amounts for half as many people, or twice as many.
• Time a walk over a distance you know, then figure out your speed.
Why it matters: math you can touch and measure is math you understand.
Values Check
Which of your core values shows up when you report a result you did not expect? Write one sentence about a time when being honest mattered more than having a neat answer.
Exit Ticket
One thing I will keep human this week, and why:
Pause & reflect
What changed in your thinking?
Write one sentence in your notebook. Name what you checked, what you chose, or what you want to explore next.
Read the video transcript
Read along, pause, or return to an idea. This transcript follows the selected lesson video.
Before you use an AI tool
Follow your course or institution's rules. Use an instructor-approved tool that permits your age, and meet any required consent conditions. Keep names, contact details, school records, and other private information out of prompts. Use fictional examples when you can.
Learning without an AI account
Follow the demonstration, pause before each answer, and do the reasoning on paper. Discuss what you would ask, how you would check it, and which decisions would remain yours.
About the characters and voices
This course uses AI-created characters and synthetic voices. Carla is an AI avatar. They help tell the story; they are not real students sharing testimonials.
Designed for high-school and community-college learners. Choose examples from your classes, work, and everyday life. Keep your completed work in your course portfolio.
