Elapsed Time Rulers - 12 hour and 24 hour Time Spans

Elapsed Time Rulers! There are many ways to teach elapsed time and over the years I've learned that having a visual time span for the students to follow is the easiest and fastest way for them to understand and map out elapsed time for themselves.

These elapsed time rulers are available in three different time spans:
- 24 hour ruler (from 12:00a.m. to 12:00p.m. to 12:00a.m. again)
- a.m. 12 hour ruler
- p.m. 12 hour ruler

I colour coded them in red and blue; red for the hours (upper half) and blue for the minutes (lower half). Five minute and fifteen minute increments are also shown in blue. Use it like a number line. Count on from the starting time to the completion time of an event. Directions are included.

Teachers can print them on transparent sheets to use with an overhead projector to demonstrate their use. To print them out for the students, use 8.5 x 14 (legal) sized paper to accommodate the full length of the rulers.
