3.MDR.5.3 worksheets: elapsed time on a number line

The standard

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.

Element 3.MDR.5.3 of Georgia's K-12 Mathematics Standards (2021, effective SY2023-24), in the Measurement & Data Reasoning strand. It sits under standard 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.

What students practice

Four pages use number lines to find how much time passed, the end time, and the start time, then solve time stories. Every interval is in hours, half hours, or quarter hours, every time sits on one of those marks, and no problem crosses noon or midnight.
