3.MDR.5Measurement and Data Problems

Expectations

• 3.MDR.5.1

  Ask questions and answer them based on gathered information, observations, and appropriate graphical displays to solve problems relevant to everyday life.

• 3.MDR.5.2

  Tell and write time to the nearest minute and estimate time to the nearest fifteen minutes (quarter hour) from the analysis of an analog clock.

• 3.MDR.5.3

  Solve meaningful problems involving elapsed time, including intervals of time to the hour, half hour, and quarter hour where the times presented are only on the hour, half hour, or quarter hour within a.m. or p.m. only.

• 3.MDR.5.4

  Use rulers to measure lengths in halves and fourths (quarters) of an inch and a whole inch.

• 3.MDR.5.5

  Estimate and measure liquid volumes, lengths and masses of objects using customary units. Solve problems involving mass, length, and volume given in the same unit, and reason about the relative sizes of measurement units within the customary system.

What mastery looks like

Georgia's Achievement Level Descriptors. The levels are cumulative: each includes the ones before it. Proficient is on grade level.

Beginning

Identify information from a pictograph, bar graph, or dot plot. Estimate liquid volumes, lengths, and masses of objects using customary units.

Developing

Create a pictograph, bar graph, or dot plot that matches a data set. Tell and write time to the nearest minute. Use a ruler to measure length to the nearest inch. Measure liquid volumes, lengths, and masses of objects using customary units.

Proficient

Solve real-life problems involving data from categorical or numerical data sets and data displays. Solve meaningful problems involving elapsed time to the quarter hour. Use a ruler to measure length to the ¼ inch or ½ inch. Solve problems involving mass, length, and volume, and reason about the relative sizes of customary units.

Distinguished

Solve meaningful, complex problems involving customary measurement units or involving reasoning related to the relative sizes of measurement units. Solve relevant problems involving elapsed time to the nearest fifteen minutes from any given time.

The same standard across grades

1. Grade 2 · 2.MDR.5

   Estimate and measure the lengths of objects and distance to solve problems found in real-life using standard units of measurement, including inches, feet, and yards and analyze graphical displays of data to answer relevant questions.

2. Grade 3 · 3.MDR.5 (this standard)

   Solve real-life, mathematical problems involving length, liquid volume, mass, and time and analyze graphical displays of data to answer relevant questions.
