Fraction Comparison Reflection

Question: You know how to compare fractions using cross products, LCD, reasoning. When is it better to use one method over another? 

When both denominators don't have numbers that are in common, you would use cross products or reasoning depending on if the question is hard to do in your head. But when the denominators can be equivalent, then you would use LCD to find out which one is bigger. But easy problems like 2/4 and 1/3, you can use reasoning because you already know how much 1/3 is and how much 2/4 is. 

Math Reflections: Factors and Multiples

Questions:

#1: Common multiples help you if you with questions that contains having to find out the common multiple of something. A common multiple is a multiple that both numbers have as one of their multiple. For example, if I had the number 6 and 9, the common multiple of 6 and 9 would be 3. But common factors help you with questions that include with finding the common factors. One example would be if there was a ferris wheel that goes for 3 seconds per round while another goes for 4 seconds. And they asked you what's the fastest time they can meet, then you would keep on adding 4+4 or 3+3 until you get a number that matches. In this case, the answer would be 12.

#2a: You can find the common factors by adding up 4+4 or 3+3 if I had a question like that ferris wheel. You keep on adding it until you spot a number that they have in common. Like 12. 12 is not the greatest common factor because you can keep on adding it up until you get 100 or more!

#2b: It sometimes provide the answer for you depending on the question. Because if the question is asking you to look for the greatest common factor, then you already know your answer.

#3a: You can find the common multiple by adding up the multiples by itself over and over again until you get a number that both numbers have. You can find the least common multiple by doing the same thing, except it's the first number you get that they have in common.

#3b: The least common multiple can also provide you the answer because if it was like the ferris wheel problem, you would need to keep on adding it over and over again until you get the seconds/time of when they meet.

Locker's problem

This problem involves with needing precise math. Because once you got something wrong, then you got the entire thing wrong. And I learned you shouldn’t over think it, or else you would get confused, then think of the wrong answer, making it not have the correct answer afterwards. So in conclusion, precision is the answer to this problem.

At first, my partner and I thought of just doing 100 circles and crossing them off, or “opening” them. But then we realized that it would take forever. So like Mr. Munden had said, it was all the square numbers and was either up to 1,000 or a little less than a 1,000. So when I got back home, I started doing all the square numbers until I got 1,000. In total: I got 31 lockers were open. And I got this by the square numbers that are up/a little below 1,000. Here’s the square numbers:

1,4,9,16,25,36,49,64,81,100,121,144,169,196,225,2256,289,361,400,441,484,529,576,625,

675,729,784,841,900, and 961. If you had counted them, you would have gotten 31 numbers. and that is the answer to the question! And at the bottom, as I had explained, you only needed to find all the square numbers up to 30. so here’s the 100 chart and showing you how many square numbers or opened lockers should be there.

Cyberbullying

      Cyberbullying

Have you ever typed mean things about your friend or even anyone? Have you ever sent out something embarrassing to the public about someone you hate, And then made fun of it by writing mean comments about? Think about it. Have you actually may have done that before, but then didn’t notice. This is called cyberbullying. Cyberbullying is online bullying. Which is talking online and saying something bad about someone. It could be chatting in gmail, or any kind of chats. You can be talking to your friends about how one of your classmates in your homeroom is really stupid online. Then everyone can see it. Everything you do leaves a footprint online. And it’s permanent there. Meaning it’s there forever! So make sure you don’t cyberbully others.

I used to think no one can see what you’re doing because once you delete it, it says it’s deleted and goes right into the trash can. But then I learned that people can scan the page you were on, and then forward it to his/her friends. Making other people know about. So if you do write bad comments about someone, others can see it, and it can hurt other peoples feelings. How I learned this was because in the computer boot camp, we watched a video about how anybody can see what you’re doing. Even now! So please, don’t do anything before you thought about it.

This learning changed my thinking on how the internet is safe. Because I never knew that people can track you and then still see what you were doing that time. So if you give your personal information, (Like passwords, where you live, phone number, etc.) then people like robbers can hack into your home. And this will impact my future because now I know that I should be more careful when I’m using the internet and not leave anything personal online. So for the big take away, I think it’s “think before you act.” Because if you thought about what you were going to do, you would know what’s right or wrong. (Or what you can and can’t do.)
