We’ve been learning about all kinds of incredible ways that we use math and numbers in the real world. Math is around us every single day, we often just don’t stop to think about it. Math can be found when we walk into stores, when we look at how many watts are in a lightbulb in our house, or even when we are using up gas in a car. Now, look around you. Is there anyone else in the room with you? How big or small is the room that you’re in right now? Math is tied into those ideas as well!
When we’re trying to determine how many people live in a certain place, that’s called population. The population of a country is just how many people live there. Do you know what the most populated country is? How about the second most populated? I think you’d be surprised to know just how many people live in those countries!
A lot of times when working with the population of countries, we use something called population density. This refers to the number of people compared to the size of a state or country. For example, New Jersey has the highest population density in the United States. This means it has the highest number of people living within its area. In order to determine that, not only is the population important to calculate but also the area.
As mentioned above, area is also an important math concept that we use when looking at states or countries. Area represents the size of something that is 2-dimensional. In math, we often try to find the area of shapes such as rectangles, triangles, and circles. This same idea is used to find the area of places where people live. Do you know what country has the largest area?
Check out our slideshow that we made to share some interesting facts we found about population and area. See if you can answer some of the math problems that we presented.
