Clockworks in an awesome way for kids of all grade levels to practice telling time. It requires students to set as many clocks as possible in two minutes. The game is completely customizable. The easy setting includes times that end in :00, :15, :30, or :45. The medium setting includes the above as well as five-minute intervals. The advanced setting includes times to one-minute intervals, and the challenge setting includes difficult elapsed time problems. In this setting, scoring one or two is impressive!
