Time to the Minute & Elapsed Time

What you'll learn

  • Tell and write time to the nearest minute
  • Solve elapsed-time problems in one-hour increments
  • Read both analog and digital clocks

Words to know

Analog clock —
a clock with hour and minute hands
Digital clock —
a clock that shows time with digits
Elapsed time —
