Which manipulatives might a teacher use to help students understand elapsed time?

Using manipulatives to help students understand elapsed time can greatly enhance their learning experience. The combination of a T-chart, number line, and Judy clock is particularly effective for this concept.

A T-chart provides a visual representation of time intervals, allowing students to break down the problem of elapsed time into manageable parts. They can write down the start time on one side and the end time on the other, making it easier to see the difference.

A number line serves as a visual tool where students can plot the start time, move along the line to represent the passage of time, and determine where the end time falls. This visual can help solidify their understanding of how time progresses linearly.

The Judy clock, which is an analog clock with movable hands, allows students to physically manipulate and visualize how time changes. They can set the hands to the start time and then move them forward to show the elapsed time, making the concept of time more tangible. By integrating these manipulatives, students can engage with the concept of elapsed time in a hands-on manner, leading to deeper comprehension.
