I'm starting my telling time portion of my math curriculum on Tuesday, and was wondering if there's any secret in teachng this effectively versus giving them a very dry run-through of what the little and long arms mean. Also, I only have one adjustable clock in my room unfortunately. I wish I had one for all my students to tinker with. Right now, all I got is the worksheet inside the math book. I somehow would like to teach it more hands-on. Any ideas?
