ILC 3rd Grade Mathematics: Unit 6 Measuring Length, Time, Liquid Volume, and Weight

This is unit 6 of 8 units. The sequence of units is available in the Read Me First Materials in each unit. 

• Section A: Measurement Data on Line Plots 
  In this section, students will learn to measure lengths in fractions of an inch—first in halves of an inch, and then fourths of an inch. Students will partition rulers with whole-number inch marks into equal intervals and then use them to measure lengths of objects in the classroom. Students will learn that measurements that are greater than one (1) can be expressed with mixed numbers, which combine a whole number and a fraction less than one (1). Students will use their understanding of the number line and rulers to interpret and create line plots that represent lengths measured in half inches and quarter inches. 
• Section B: Weight and Liquid Volume 
  In this section, students will learn that weight is a measure of how heavy something is and that grams and kilograms are units for measuring weight. Students will learn that liquid volume is the amount of space that a liquid takes up. 
• Section C: Problems Involving Time 
  In this section, students will learn to tell and write time to the nearest minute and to show given time on an analog clock. Students will solve elapsed time problems with an unknown start time, unknown duration, or unknown end time. As students solve problems, they will continue to build their fluency with multiplication (especially multiples of 5, 10, and 15), addition, and subtraction. 
• Section D: Explore the Fair 
  In this section, students will solve problems that involve measurements of weight, liquid volume, and time in the context of a state or county fair. The problems will prompt students to use all four operations: addition and subtraction within 1,000, and multiplication and division within 100.
