Four parts, one coherent lesson
Every part returns to one picture: the arrow board. A vector is drawn as an arrow with a direction; a scalar is just a number with a unit.
Lesson plan
A timed 45-minute sequence: a simulation-led hook, the arrow board, Quiz-Quiz-Trade, a sort checkpoint, and an exit ticket. Objectives, vocabulary, examiner traps, differentiation and a timing and contingency note.
Worksheet and answers
Six original questions on defining and classifying quantities, distance against displacement, and representing a vector, with a full worked answer key.
Slides
Ten editable slides with accurate diagrams: the round trip, the arrow board, the classification, and the cooperative task.
Quiz-Quiz-Trade and sort
Printable quantity cards for the cooperative task, plus a scalar and vector sort mat for the group checkpoint.

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 single test runs through all of it: does this quantity need a direction?
