Elapsed Time

Johnny left his house at 3:30.  He arrived at his grandma's at 5:55.  How long did it take for Johnny to get to his grandma's?

:blank stares:

This is usually how my lesson on elapsted time goes.  I've tried having two clocks in show the different times.  Nothing.

So, I was SUPER excited to win this

How dang cute is that?!  You set the one clock for the start time, the next clock for the end time.  The kids can write their answers on white boards, hold them up, and you can hit the elapsed time button.  So neat!

You can also use it to find start times or end times (Sally woke up at 7:30.  One hour and twenty minutes later she was at school.  What time was it when she arrived at school? or Cindy was at lunch at 11:00.  Forty-five minutes before she was in music.  What time was she in music?)

Love this clock and can't wait to use it!
