Perfect for kids who are ready to learn to tell time, this learning clock features hands that rotate with a gentle click, marking off the minutes as they go.

Slide open the "digital clock" window to check the answer!

Then place the cards back in the storage slot at the back of the clock for neat and tidy storage. This part is cataloged in the U.S. Government catalog under NSN 5330-00-006-1149, indicating validated use in U.S.
