Time and Quantity Problem Solving

This video tutorial covers third-grade math concepts, focusing on time calculations using a number line. The teacher demonstrates how to calculate time by moving both backward and forward on a number line, solving various problems involving time. The lesson includes practical examples, such as determining start and end times and distributing items equally. The session concludes with a spiral review to reinforce the concepts learned.
