Time Number Line, set of 10

Have students use these handy time number lines to calculate elapsed time. Write beginning and end times on the dry-erase surface (in either analog or digital format) and write on the number line to calculate elapsed time. Or, use 1 and 2 cm cubes to represent 1/2 hour and hour to see how much time has passed. Cards are 19" x 4".
