Students begin by learning to tell and write time to the nearest minute using analog and digital clocks in Topic A (3.MD.1). They understand time as a continuous measurement through exploration with stopwatches and use the number line, a continuous measurement model, as a tool for counting intervals of minutes within 1 hour (3.MD.1). Students see that an analog clock is a portion of the number line shaped into a circle. They use both the number line and clock to represent addition and subtraction problems involving intervals of minutes within 1 hour (3.MD.1).
