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.

• 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 Mathematics 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.
