Compare Numbers and find the Scale Factor by Multiplying 4-16

Introduce multiplicative comparison. How much greater is 24 than 8? Instead of thinking additively that 24 is 16 more than 8, think multiplicatively and find the scale factor – 24 is how many times 8. Draw a bar model or use multiplication facts to know 3x8 = 24, so 3 is the scale factor and 24 is 3 times as many as 8.
