These printer friendly task cards are designed with differentiation in mind. There are 3 sets of cards. In each set,16 of the 24 cards have visuals (clocks or number lines).
Set A: Elapsed time with hours only. The starting and ending times are both right on the hour (i.e. 9 p.m.)
Set B: Elapsed time with either hours only or minutes only. Starting and ending times all fall on a quarter hour minute mark.
Set C: Elapsed time with minutes. Starting and ending times all fall on a 5 minute mark. (Common Core aligned to 3.MD.1: Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.)
