In Grade 1, students learned to read time from an analog clock to teh hour and half hour. They also learned to relate time to daily activties using terms such as "o'clock" and "half past". In Grade 2 they went on to learn about the minute hand, and that after the hour can be read in skips of five minutes. They have learned the digital notation of time, and the use of A.M. for time from midnight and P.M. for time from noon.
In this chapter, students will learn about reading and telling time to the minute using the terms "past" and "to". For example, 5:20 is 20 minutes past 5, and 9:45 is 15 minutes to 10. They will move on to learn how to convert time expressed in hours and minutes to minutes and vice versa. Building on what students have learned about elapsed time in Grade 2, they will now learn that timelines can be used to show the start and end time of an activity to help them find how long an activity will last.
Determining elapsed time is the most challenging part of the time concepts. Part fo the challenge for students is that there are three different elapsed time scenarios involving finding start time, end time, or elapsed time. Students will need to determine which part of the problem they are trying to find. They will have to rely heavily on their counting skills to determine the necessary time. Students will be encouraged to use timelines and clock face templates as tools for finding elapsed time.
