Tell a seven-year-old that a party starts in three hours and they will ask, “So when is that?” every few minutes. This 2nd grade start and end time word problems worksheet gives them the tool to answer it themselves. Nine short stories fill the page. Henry starts basketball practice at four in the afternoon and plays for 3 hours. Then birds stop chirping at dawn, Derrick mows the lawn from noon and Lucy babysits in the evening. Some stories give the start and ask for the end; others give the end and ask when it began. Every gap is a whole number of hours. A second page gives the answer key.
