The standard
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.
Element 4.MDR.6.1 of Georgia's K-12 Mathematics Standards (2021, effective SY2023-24), in the Measurement & Data Reasoning strand. It sits under standard 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.
What students practice
Students find elapsed minutes and unknown start or end times with open number lines, multiply and divide equal intervals, and solve two-step time stories. Metric pages fill two-column equivalence tables, express whole and mixed units from printed facts, read a gram dial and milliliter container, and solve measurement stories including like-denominator fraction measures. Pages 13 and 14 combine time and metric skills.
