ACE 1.3: American Records

Today both groups did more work with ratios, fractions, percents, and differences to compare quantities.

LARGE GROUP
The large group did an assessment on their ability to move between fractions, decimals, and percents. We compared our results from the pet survey, and then we talked about problem 1.3, where we compared record sized trees and people to each other.
