Digital Clock Games: Hours Earlier

Ages 5–7 · 4 minutes · Math

Play games that involve moving the time backward using hours

This lesson is a game, where each round gives and time and asks what time it was some number of hours earlier. If a student can read all the times on a digital clock and do basic subtraction, they are ready for this lesson.

Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
