Talking about reading the time, there are two systems which are commonly used in the world: 12 hour system (using a.m./p.m.) and 24 hour system. Grade 3 students were also learning both systems in reading the time. Students learned to find out how to read the time in 24 hour system with the help of the clock which is designed to help the students to identify the time in 24 hour system. They manipulated the clock and had fun to read the time in 24 hour system. It was great!!!
