Sequence events by time

Temporal order is determined by comparing when events occur: earlier events precede later events, and events can be described as first, next, last, before, after, or between. The ordering may be inferred from familiar clock times to the nearest five minutes, a.m./p.m. labels, and calendar sequences such as days and dates, while distinguishing time of day from duration. Advanced elapsed-time problems and generalized time-interval reasoning are not included.

Detailed Explanation: Sequence events by time

To put events in time order, compare when each event happens.

  • An event that happens earlier comes first.
  • An event that happens later comes next or last.
  • An event can happen before, after, or between other events.
  • Remember: a.m. is generally morning, and p.m. is generally afternoon or evening.

Example:
Mia has these events on the same day:

  • She eats lunch at 12:00 p.m.
  • She goes to bed at 8:30 p.m.
  • She eats breakfast at 7:15 a.m.

Step 1: Look at the a.m. and p.m. labels.
Breakfast is in the morning, so it happens before the p.m. events.

Step 2: Compare the p.m. times.
Lunch at (12:00)(12{:}00) p.m. is earlier than bedtime at (8:30)(8{:}30) p.m.

Step 3: Put the events in order.

  1. First: Eat breakfast at (7:15)(7{:}15) a.m.
  2. Next: Eat lunch at (12:00)(12{:}00) p.m.
  3. Last: Go to bed at (8:30)(8{:}30) p.m.

So, breakfast happens before lunch, and lunch happens before bedtime.
