Comparing and Calculating Time - PowerPoint

In the Year 3 Maths curriculum, students explore the concept of time, learning how to compare and calculate different lengths of time. The lesson delves into practical examples, such as determining the duration of various activities and understanding when they start and finish. For instance, students compare the times it took for three fish to complete a swimming race, with times ranging from 1 minute and 45 seconds to 2 minutes and 5 seconds, to figure out the order in which the fish finished the race. This exercise helps them understand the concepts of longest and shortest times, and how to rank durations accordingly.

Further exercises include worksheets where students must circle the correct answers to questions about time. They are asked to identify the slowest participant in a journey to Penzance between an aeroplane, car, and train, and to determine who arrived second or last in various scenarios, such as a school walk or a hopping contest. The exercises are designed to reinforce students' ability to compare lengths of time and to use this skill in practical situations. Additionally, the lesson covers how to calculate the difference between two times to find out how long an activity takes, as well as counting on or back to work out start and finish times for events like exams or sports matches.
