This chart is like a hundreds chart, only after 59 it starts over at 00. It is designed to help scaffold students at the beginning of elapsed time study to help them see that if you start something at 3:48 and go for 20 minutes, you will end up at 4:08 (as opposed to 3:68). It helps them see that after 59, the minutes start over and they need to go up one hour.
There are 3 charts per page, and the heading is in Spanish because I teach math in Spanish. However, you can ignore the heading and explain and use the chart in any language.
