One of the things the lesson recommends is using a numberless clock like the one below. Click on the picture to get your own copy.
First I drew the minute hand directly pointing to a 5-minute mark. "How many minutes past the hour is it?" We practiced with a few of those easier ones before I started pointing the minute hand to one of the smaller lines, which of course is a more difficult concept.
I got pretty lucky too, because MyBinding.com graciously sent me some dry erase pockets, which came in mighty handy for practicing this skill.
Each group got their own dry erase pocket. As one child held the pocket, the others wrote the number of minutes it was showing. The child would pass it, turn it around to the other side, and everyone would count and write the minutes again. When they had completed both sides of their pocket, I could quickly erase and draw new hands. Pretty slick!
Like I said, this was merely a glimpse into the lesson. I left out lots of good parts. You should really check out the article. You also should check out MyBinding.com and their dry erase pockets. They saved me copies and time, and no doubt they can be used numerous other ways as well!
