This worksheet was created for third grade elementary students to explore the concept of Elapsed Time through a fun detective format. It contains one easy word problem where students are asked to find the "end time" and four word problems where students are asked to find the amount of "elapsed time". Every problem is geared towards the detective theme and the problems are easy for students to understand. I had my students draw a T-chart on laminated "paper white boards" and they used this to solve these elapsed time word problems. Use this worksheet as homework or for extra in-class practice!
