These 12 pages of notes and practice walk students through the process of using a number line to find the start time, end time, and elapsed time of given problems.
There are four notes pages to introduce students to the three types of elapsed time problems. The end time and start time notes are each followed by two pages of practice, while the elapsed time questions are followed by four pages of practice. Each includes easier problems (5 minute increments) on the first page and slightly harder problems (1 minute increments) on the second page. For the elapsed time practice, the additional two practice pages (practice #3 and #4) include more challenging multi-step questions.
