Representing Quantities of Time with Diagrams

This video tutorial teaches how to represent and calculate time using diagrams. It covers key time phrases like 'quarter after', 'half past', and 'quarter till', and explains how to add and subtract time while considering the 60-minute hour limit. A real-world problem involving Mrs. Sabios is solved using diagrams, and an alternative method of working backwards is demonstrated. The lesson emphasizes the importance of organizing time calculations to avoid errors.
