Scalar × Hops on a Number Line

Complex Book 5, Lesson Page 1, Section 1

What you'll work on

Interpret multiplication as repeated hops on a number line and predict the direction and landing point based on the signs of the scalar and the hop size.

Big Idea for this lesson

Multiplication is repeated movement on a number line. Multiplying by a negative scalar reverses direction; multiplying by a positive scalar keeps the same direction.
