Can you recite your best friend’s phone number? Probably not thanks to our cell phones where we just have to press our friend’s name and our cell phone instantly dials him. However, there was a time when we had to memorize phone numbers.
Today, I can barely remember my own. Including the area code, each phone number includes 10 numbers. In most cases, you can remember 3 numbers or things at a time. However, you can’t do that with phone numbers based on the amount of numbers that are included.
Read the number below. See if you can memorize it. How do you memorize that phone number?
So, most of the time, people can memorize the first and second set of 3 numbers, but then they must remember the last 4 numbers. Did you say all four numbers together, or did you break them down to two and two numbers? The problem is that 3 is not a factor of 10.
Maybe we can find a better way to remember 10-digit phone numbers. Let’s first find the factors for 10.
You have two choices to make to memorize a 10-digit phone number if you want to memorize equal amounts of numbers instead of the 3-3-4 pattern that most of us use. So, you could either memorize 5 digits at once. That seems difficult.
Most research shows people can remember 3 items at once. When you get to 5 items followed by another set of 5 items, that doesn’t seem to be the best idea. Instead, let’s try memorizing the numbers in pair.
See if you can do it. Look at the random set of 10 numbers below. Try to memorize them using the pair method.
How did you do? I decided to leave off the hyphens in between the pairs of numbers to see if you would memorize that number by remembering the pairs of the numbers. Did it work?
Factors of 10 are 1, 2, 5, and 10
While thinking about painting your fingernails, you must decide what colors you will use. If you want an equal number of fingernails painted with a certain color, think about how many choices you will have? Use the factors of 10 to help you answer that question.
You will have 4 choices with painting your fingernails. You could paint them all different colors, or you could paint them all the same color. Then that would follow your rule about painting the same number of fingernails with the same color. However, you could also paint 5 fingernails one color and then 5 fingernails another color. Last, you could paint two fingernails with five different colors.
As a good bowler, you knock down 5 pins with your first roll of the bowling ball. If you have gotten into a habit of knocking down 5 pins with each roll of the ball, how many times would it take you to knock down all 10 pins?
You could knock down all ten pins during your turn because you get 2 turns to roll a ball down the lane. If you knocked down 5 pins with the first roll, then you would knock down 5 pins with the second roll. Five is a factor of 10. Ten divided by 5 is 2, so you can knock down all ten pins in 2 rolls based on your strategy.
While looking at the 10-day weather forecast on TV, you want to compare every 2 days. Will you be able to do that without having any extra days left over?
Yes, you will be able to compare every 2 days on the 10-day weather forecast. Two is a factor of 10, so you will end up with 5 groups of 2 days.
It is important to find the factors of a number like 10 because you may need to divide 10 into equal parts. If you have a group of 10 people or 10 objects and you need to divide it equally, then you will need to know the factors of 10. These numbers will show you how many groups you will have and how many objects will be in each group.
It is needed to find all of the factors of 10 if you need to find all of the options for 10. If you don’t because you are simply dividing a number into 10, then you may not need to find all of the factors. In a math problem, you will need to find all of the factors of a number like 10 if the question asks you to find the factors of that number. You can’t just find some of the factors of a number. If you need to find all of the factors of a number like 10, then divide all numbers below 10 into 10. If there is a remainder, then that number is not a factor.
Ten is such a nice, round number that there are probably many things that come in groups of 10. There are probably too many to count. Of course, you have ten fingers and ten toes. There are ten years in a decade, and ten decades in a century. Many people use the amount of time, 10 minutes, frequently.
