This worksheet is designed to help learners calculate durations between times by using a timeline to partition the duration into sensible amounts. the worksheet ramps up the difficulty but with scaffolding along the way.

Section A asks learners to give a missing time for a given duration before section B then reverses the instruction and asks for a duration between two simple times with either the times being in the same hour or a whole number of hours apart.

Sections C and d then lead learners through the process of splitting the durations by working up to the next whole hour.

Section E then provides more challenging times for learners to use the new process.
