4.MDR.6Measurement & Data Overview

Expectations

• 4.MDR.6.1

  Use the four operations to solve problems involving elapsed time to the nearest minute, intervals of time, metric measurements of liquid volumes, lengths, distances, and masses of objects, including problems involving fractions with like denominators, and also problems that require expressing measurements given in a larger unit in terms of a smaller unit, and expressing a smaller unit in terms of a larger unit based on the idea of equivalence.

• 4.MDR.6.2

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

• 4.MDR.6.3

  Create dot plots to display a distribution of numerical (quantitative) measurement data.

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

Given a measurement in metric units, express the measurement using a different metric unit (e.g., 2 kilograms is 2,000 grams). Determine whether a set of data is categorical or numerical. Identify the dot plot that represents a set of measurement data to the nearest 1/2, 1/4, and 1/8 of an inch.

Developing

Determine an appropriate representation of data based on whether the data are categorical or numerical. Create or complete a dot plot that represents a set of measurement data to the nearest 1/2, 1/4, and 1/8 of an inch.

Proficient

Solve problems involving elapsed time and solve multi-step problems involving elapsed time and metric units. Solve problems using bar graphs, pictographs, and dot plots. Solve problems involving addition and subtraction of fractions with common denominators by using information presented in dot plots.

Distinguished

Solve complex real-life problems involving measurement data, including finding equivalent measurement units and using information presented in bar graphs, pictographs, and dot plots.
