CCSS Description: (+) Solve problems involving velocity and other quantities that can be represented by vectors.
(+) Multiply a vector by a scalar. a. Represent scalar multiplication graphically by scaling vectors and possibly reversing their direction; perform scalar multiplication component-wise, e.g., as c(vx, vy) = (cvx, cvy). b. Compute the magnitude of a scalar multiple cv using ||cv|| = |c|v. Compute the direction of cv knowing that when |c|v ≠ 0, the direction of cv is either along v (for c > 0) or against v (for c < 0
This activity is designed to get learners recognizing parallel and perpendicular column vectors. Learners need to circle pairs of parallel vectors in black and perpendicular vectors in blue. There are six pairs of each to find. Learners should consider multiples and what makes two vectors perpendicular.
