This set contains two versions of elapsed time task cards…one with self-checking QR codes and one without. (You will need a device with a QR reader to use the QR codes).
There are also several ways to differentiate with these task cards:
Odd numbered cards stay within the same hour.
Even numbered cards cross over an hour.
The top two cards on each page are given the beginning time and the time it took and students must find the ending time.
The bottom two cards on each page are given the beginning time and the ending time and students must find the amount of time in between.
