Two different examples of elapsed-time word problems are: Seth went home at 3:35 p.m. and told his teacher he would return in 45 minutes - at what time will Seth return to school? Allison fell asleep at 8:00 p.m and woke up at 6:13 a.m. - ow long did Allison sleep?
Elapsed-time word problems are used to help a student apply the concept of time to real-life situations. When teaching, it is helpful to hold students accountable for their time. Use a timer and stick to limits that are set. This helps students grasp a better understanding of how time applies to different areas of their lives.
