Eight start clocks set to quarter hours, each with an amount of time to add in 15-minute steps (like 2 hours 45 minutes). Children write the end time. Quarter-hour steps keep the arithmetic friendly while children learn the method, which is the 3rd grade goal: solving elapsed time problems by adding time intervals.
Teach the hour-jump method: from 10:45, add 15 minutes to reach 11:00, then the rest. Some problems cross 12 o'clock, which is a good chance to talk about a.m. and p.m. When this is easy, try the five-minute elapsed time worksheets.
Yes. The 3rd grade standard is to tell time to the nearest minute and solve word problems about time intervals in minutes.
The clock starts over at 1. 11:30 plus 2 hours is 1:30. On a real day it switches between a.m. and p.m.
