Task statements for students to write on. Unit: 3.6 Measuring Length, Time, Liquid Volume, and Weight (Grade 3). 3.6 Measuring Length, Time, Liquid Volume, and Weight Unit Goals Students generate and represent length measurement data in halves and fourths of an inch on line plots. They learn about and estimate relative units of measure including weight, liquid volume, and time, and use the four operations to solve problems involving measurement. Section A Goals Measure lengths using rulers marked with halves and fourths of an inch to generate data for making a line plot. Section B Goals Measure and estimate weights and liquid volumes of objects. Section C Goals Solve problems involving addition and subtr
