Vector Addition: Direction & Sign

Lesson Page 4, Section 1

What you'll work on

Understand that positive and negative signs in vector expressions represent direction (forward or backward), and that adding two vectors combines their movements.

Big Idea for this lesson

$A horizontal stone-colored painted number line with evenly spaced tick marks, two distinct painted arrows hovering above it — one solid warm amber arrow pointing right toward the positive direction, one cool slate-blue arrow pointing left toward the negative direction. Painterly soft edges, ivory background, no text or labels.$

A vector is a math arrow that points in a direction. Positive means move forward; negative means move backward. When you add two vectors, you combine their movements one after the other.
