Analog Clocks: Quarter Hours

Analog Clocks: Quarter Hours

Ages 6–8 · 17 minutes · Math

A continuation of analog clocks, focusing on quarter hours

In this lesson, we start to read times on the quarter hour, like 2:15 and 8:45. We also look at how both of the hands move around the clock. If a student already knows how to read analog clock times on the hour and half hour, they are ready for this lesson.
