ACE 2.1, 2.2, and 2.3: Finding Equivalent Ratios

LARGE GROUP
We talked about the POW, Football, from last week and we started looking at the new POW, Flags. Then we worked on Problem 2.3, Finding Equivalent Ratios. Students showed that you can use the same strategies for finding equivalent fractions on ratios, by multiplying the numerator and denominator by the same number to scale up the ratio, or dividing the numerator and denominator by the same number to scale down the ratio. Class notes may be downloaded here.
