A question for the whole room
One story to open. A room full of ideas to test.
Ready in three steps
- Open the story.Read and try the first pages together.
- Pause for a prediction.At the story’s question, read its choices aloud. Invite a vote and ask, “What makes you think that?”
- Run it. Watch. Wonder.Choose the class’s prediction, run the experiment, and compare what happened with your guesses.
Different guesses are welcome. The experiment gives everyone something to rethink.
Something to put on paper
A one-page prediction and observation sheet. No answers included.
After the experiment: discussion notes
Talk about what happened
- Predict first: an all-blue 10-row picture needs 10 run tags. If a 3 × 3 sun patch splits three of those rows, will the whole picture need 13, 16, or 30 tags?
- Predict a new case: if one stray red pixel splits a long blue row, how many run tags would replace that row's single tag?
- Real photos still send fast even though they're busy. Predict how — what do you think the phone gives up to make that happen?
Where it shows up in real life
- A photo that's 'too big to text' until the phone compresses it
- A plain screenshot of a webpage that saves as a tiny file
- A detailed nature photo that stays a big file no matter what
