Digital Clocks: Quarter Hours

Digital Clocks: Quarter Hours

Ages 4–6 · 9 minutes · Math

Learn to read times ending in 15 and 45

In this lesson, we move on from reading full and half hours to reading quarter hours. If a student knows their numbers up to 60 and already knows how to read times on the hour and half hour, they are ready for this lesson.
