21st century skills activity
Quiz-Quiz-Trade with twelve quantity cards, plus a scalar and vector sort, with a full facilitation guide so both structures run faithfully.
Send learners to the lesson online
This bundle pairs with the student topic page Scalars and vectors, and the hook runs on the site simulation The Round Trip Trap: as a journey goes out and back, distance and speed keep growing while displacement and velocity carry a direction and return to zero. That contrast is the whole lesson.
One question, asked of every quantity
Classifying is quick to say but easy to get wrong, so the lesson gives many short, low-stakes attempts. After the simulation makes the case for direction, the arrow board fixes the two definitions, and Quiz-Quiz-Trade sends learners around the room giving a reason for each card, not just a label.
A group sort then asks them to defend eight placements, and random call keeps every learner accountable. The activity ships with a full facilitation guide for both structures, and the single test runs through all of it: does this quantity need a direction?
