Digital Clock Games: One Minute Earlier

Digital Clock Games: One Minute Earlier

Ages 5–7 · 4 minutes · Math

Play games that involve moving the time backward by one minute.

This lesson is a game, where each round gives and time and asks, "What time was it 1 minute earlier?" If a student can read all the times on a digital clock and count backward, they are ready for this lesson.
