This document includes 4 worksheets. Print only those pages that you need. Note also that the steps or "hops" shown on the number line examples might not be the best options for all time spans and/ or your children may pick different methods for calculating how much time has lapsed; in most cases there is no right or wrong method. See here for more help with elapsed time.
