Georgia 3.MDR.5

3.MDR.5 is a Georgia mathematics standard. These are the expectations under it.

• 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...

• 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 un...

01

What Students Need to Do

Students solve word problems about distance, capacity, weight, and time. They choose useful units and operations. They also read tables, picture graphs, bar graphs, and scaled graphs to compare data and answer questions.

02

What Mastery Looks Like

Students select sensible units, find missing measurements, and explain why they added, subtracted, multiplied, or divided. They read scales and graph labels accurately, then use the data to answer questions.

03

Common Misconceptions

Students may choose the wrong unit, such as grams for liquid volume or centimeters for time. They may add when a problem asks for a difference, confuse start and end times, or read graph intervals as single units.

04

How to Assess It

Give this exit ticket: “A bottle holds 600 milliliters. Mia pours out 250 milliliters. How much remains, and which graph bar should show that amount?”

1. 01

   Set up stations where students measure a book, weigh classroom objects, pour colored water, and record task times.

2. 02

   Ask students to explain in writing how they chose the operation and unit for a measurement word problem.

3. 03

   Play Measurement Match by pairing problem cards with unit cards, operation cards, and answer cards.

4. 04

   Use a class snack survey to make a bar graph, then calculate package mass, drink volume, and preparation time.

• 1.MDR.6

  Use appropriate tools to measure, order, and compare intervals of length and time, as well as denominations of money to solve real-life, mathematical problems a...

• 4.MDR.6

  Measure time and objects that exist in the world to solve real-life, mathematical problems 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.
