I've been teaching about the Muslim prayer names and times for the last couple weeks. I had an idea use our prayer clocks and a real clock to not only teach prayer times, but the concept of telling time. I have our 5 prayer clocks arranged under the real clock. It is the twins "job" to tell me when the prayer clock matches the real clock. As a result, we have discussed the the big hand, little hand and what "o'clock" means. So when the clocks match, they are suppose to come to me and say, "Mommy, Mommy it's prayer time!" They really feel involved and are having fun.
