I found that about one-third or so of my fifth graders, every year, could not tell time on an analog clock. Oh, no. As it turned out, the lessons I made were helpful to most of the class because even the kids who thought they could tell time weren't that hot at it.
This lesson consists of
a one-page very simple summary of how to tell time on an analog clock,
two practice pages, and
plenty of clipart image files you can use and adapt to your own style.
The two practice pages can be used as a pretest or post tests, as well as practice. Let me know if you want more practice. There is no key, because I feel sure you can tell time. ;
