We use the mountains and hills to teach elapsed time but we also have students plug the times into an SEF chart (S-start, E-elapsed, F-finish). This helps them organize their work and know which part of the problem they are missing. When students write the the time below the mountains and hills, I have them turn their paper sideways so they have room to write.
