Georgia 4.MDR.6

4.MDR.6 is a Georgia mathematics standard. These are the expectations under it.

• 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, dista...

• 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.

01

What Students Need to Do

Students measure objects and time using suitable tools and units. They solve practical problems with those measurements and answer questions by reading labels, scales, and values on graphs.

02

What Mastery Looks Like

Students choose a suitable tool and unit, measure accurately, and solve problems involving their measurements. They find elapsed time and use graph labels, scales, and data points to support answers.

03

Common Misconceptions

Students may choose the wrong unit or leave units off an answer. They may subtract clock times as ordinary numbers or read graph intervals as single units. They may report the tallest bar without matching it to the correct label.

04

How to Assess It

Give an exit ticket with a start time of 2:35, an end time of 3:20, and a small bar graph. Ask for the elapsed time and one graph-based comparison.

1. 01

   Set up stations with rulers, scales, measuring cups, and clocks, then have students measure objects and record each value with its unit.

2. 02

   Show a class measurement graph and ask, "What claim can you make, and which two data points support it?"

3. 03

   Play a card game matching start times, end times, and elapsed times, with students checking each set on an open number line.

4. 04

   Compare two bus schedules and a ridership bar graph, then choose the better route and explain the choice using time and data.

• 3.MDR.5

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

• K.MDR.7

  Observe, describe, and compare the physical and measurable attributes of objects and analyze graphical displays of data to answer relevant questions.

• 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 y...

• 5.MDR.7

  Solve problems involving customary measurements, metric measurements, and time and analyze graphical displays of data to answer relevant questions.
