Everyone learns math in school and it is extremely important to our everyday lives. In fact, did you know that just about all of us, including adults, use math every day? We might use math in small ways when we count out money at the grocery store or cut a pizza into equal slices for everyone. Your teacher uses math to add up all the students’ grades. On an even larger scale, people use math to predict the weather, understand science, or run their businesses. Most aspects of our world are based on math. In fact, even art uses math. Did you know that a lot of Leonardo Da Vinci’s paintings used high level mathematical principals to create the most pleasing images? Check out the fun resources we’ve compiled to learn more about how we use math every day.
Addition and Subtraction
Addition and subtraction are the most basic parts of math. We can use these concepts to help us count or calculate certain amounts quickly. When we go shopping, we use addition and subtraction skills to figure out how much money we have to pay. On a road trip, we use the same technique to calculate how long it might take us to arrive at our destination.
Multiplication and Division
In situations when we have to add many groups of items that are each the same number, we can use multiplication. For example, suppose your teacher is in charge of calculating how many children are in the school. If there are five classrooms, with ten children each, the teacher can use multiplication to know that there are fifty students in total. On the other hand, division is used to split an amount into equal parts. If you have a chocolate bar, you can use simple division to split it equally among you and your friends.
Measurements are fantastic tools that help us to calculate the amounts of many different things. We can use measurements to calculate time, distance, speed, volume, and temperature. The way we measure things has changed a lot over time. In ancient times, people would rely on the sun and shadows to measure the time, while today we have digital clocks! Even if you haven’t realized it, you’ve likely already used measuring techniques before. Can you guess where? In the kitchen, of course! Baking is an exercise in measuring. When we bake a cake, we measure the volumes of many different ingredients using measuring spoons, cups, or the weighing scale.
Probability is the likelihood of something happening. We might wonder about the probability that it will snow tomorrow. If it’s summer, then the probability would be very low or even zero. However, in the winter, that probability would be very high. Instead of simply thinking about probability in terms of high and low, we can calculate it to an exact number. In the case of weather, scientists use advanced tools to figure out the probability of the next day’s temperature and outdoor conditions. Probability is all about making predictions, or educated guesses. The first step is to gather as much data about the issue as possible. This data can then be organized into graphs, charts, tables, or pictographs. In this way, we can start to see a pattern in the data. The pattern helps us to guess (based on past data) how it will evolve next.
