Teacher's field guide

What Students Need to Do: Students compare a continuous record, such as a temperature graph, with the same readings stored as numbers. They ask questions that can be tested about copying, sending, and storing each version.
What Mastery Looks Like: A student asks, 'After three copies, which has fewer errors, the graph or the number table?' They use the results to weigh copying accuracy against detail lost to rounding.
Common Misconceptions: Students may think digital copies can never be damaged or lost. They may assume rounded numbers capture every change on a graph, or that 'better' is a measure without saying what to measure.
How to Assess It: Exit ticket: Rewrite 'Is digital better?' as a testable question comparing copies of a temperature graph and a rounded number table. Name one measure and one trade-off.

Lesson moves

Have pairs copy a temperature curve and its rounded-number table three times, then compare copy errors and lost detail.
Ask students to rewrite 'Is digital always clearer?' as a testable question that names a measure of clarity.
Give teams cards reading 'Which is best?' and 'Which has fewer errors after five copies?'; award points for improving vague questions.
Show a printed class photo and its phone scan; have students choose which to archive, considering damage, deletion, and copying.
