This Application Problem is a part of the Lesson 7, Unit 6, Grade 3. The chart shows the lengths of straws measured in Mr. Han's class. Use color to customize the presentation of the data in the chart. Enhance learners' perception of the information by lightly shading every other row, highlighting numerators and/or denominators, or consistently writing whole numbers in a specific color (e.g., using red for 4). How many straws were measured?
