    I use the IM/OUR curriculum so I this is how I am thinking of these

    Multiplicative Comparison:

    -situations involving scale factors/scaled copies

    A rectangle has a width of 2 and height of 4. A scaled copy of the rectangle has a width of 6 and height of 13. What is the scale factor?

    Composed Unit:

    -situations like recipes, shopping/costs, mixing colors, time and distance (constant of proportionality)

    A turtle went 6 feet in 42 seconds? How far could it go in 3 seconds?
