Strand: MEASUREMENT AND DATA (3.MD)

Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects. (Standards 1-2). Represent and interpret data (Standards 3.MD.3- 4). Understand concepts of area and relate area to multiplication and addition (Standards 3.MD.5-7). Recognize perimeter as an attribute of plane figures and distinguish between linear and area measures (Standard 3.MD.8).

Standard 3.MD.1

Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, for example, by representing the problem on a number line diagram.

• Dajuana's Homework
  The purpose of this task is for students to work on elapsed-time questions. This task includes three different elapsed time situations: end-time unknown, elapsed time unknown, and start-time unknown.
• Elapsed Time Two
  This lesson can be used to help students understand how to read a clock, as well as understand addition and subtraction with time.
• Grade 3 Math Module 2: Place Value and Problem Solving with Units of Measure (EngageNY)
  Module 2 uses place value to unify measurement, rounding skills, and the standard algorithms for addition and subtraction. The module begins with plenty of hands-on experience using a variety of tools to build practical measurement skills and conceptual understanding of metric and time units. Estimation naturally surfaces through application; this transitions students into rounding. In the modules final topics students round to assess whether or not their solutions to problems solved using the standard algorithms are reasonable.
• Grade 3 Unit 6: Measurement (Georgia Standards)
  In this unit students will tell and write time to the nearest minute and measure time intervals in minutes. Solve elapsed time, including word problems, by using a number line diagram and reason about the units of mass and liquid volume.
• Measurement and Data (3.MD) - Third Grade Core Guide
  The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for Third Grade Mathematics - Measurement and Data (3.MD)
