Math: Elapsed Time, Making Change, and Counting Money

Math is a fundamental subject that is essential for everyday life. It involves various skills and concepts, including elapsed time, making change, and counting money. These skills are critical for children to develop, as they are necessary for making purchases, managing money, and understanding the passage of time. In this article, we will explore these subtopics in more detail.

Elapsed Time

Elapsed time refers to the duration between two events. Understanding elapsed time is important because it helps us track how long tasks take to complete, how long events last, and how much time has passed between two events. For example, if you start a task at 10:00 AM and finish it at 11:30 AM, the elapsed time is 1 hour and 30 minutes.

To calculate elapsed time, you typically subtract the earlier time from the later time. For example, if an event starts at 1:00 PM and ends at 4:00 PM, the elapsed time is 3 hours.

Making Change

Making change is another important skill in math. It involves determining the amount of money you need to give to someone else as change after making a purchase. For example, if you buy an item that costs $5 and you give the seller a $10 bill, you need to give them $5 in change.

To make change, you typically subtract the cost of the purchase from the amount of money you have. In the above example, you would subtract $5 from $10 to get $5 in change.

Counting Money

Counting money is another essential skill in math. It involves recognizing and counting the different denominations of currency, such as pennies, nickels, dimes, quarters, and dollars. For example, if you have 5 pennies, 2 nickels, and 1 dime, you have a total of 8 cents.

To count money, you typically group the denominations together and count the groups. For example, if you have 3 pennies, 2 nickels, and 1 dime, you have 3 + 2 + 1 = 6 coins, and since each penny is worth 1 cent, 3 pennies are worth 3 cents, and so on.

Resources for Practice

There are various resources available to help children practice these skills. For example, you can find worksheets to help children practice making change from different starting amounts. Additionally, you can find problem-solving journals that include word problems related to elapsed time and money, which can help children develop critical thinking and multi-step problem-solving skills.
