A Review

 

This quarter, I’ve finally moved onto Algebra II, but the first few lessons are just reviews of the past lessons in Algebra I. I haven’t moved onto more difficult topics yet, but I’m excited to challenge and push myself even further in Math.

A Quite Difficult Math

Being a Grade 9 student, each subject gets more difficult each day as I learn something new or review something I’ve learned before. A particular subject used to take me an hour to finish a lesson or two. Now,  it takes me an hour to finish half a lesson or if I’m lucky, a whole lesson. That subject is Math. Math lessons or problems get longer and get more difficult to solve as I move forward with the textbook. Aside from it being time-consuming, I enjoy it either way. I do my best to enjoy it because I know it would definitely help me in the future.

The quizzes I answered are on the next page.

Algebra Problems

    This quarter, I didn’t answer as much as before because the lessons are becoming more difficult to understand and are starting to get longer. In all honestly, I was only able to finish six lessons this quarter due to the fact that I’m beginning to have a difficult time in Math. What I decided to do is to pick out five problems that I’ve learned how to solve in the six lessons and answer them. Really out of the box, right? I wasn’t able to finish my requirements for Math in one school year which means that I have to study during summer, but I truly enjoy the subject. It may challenge me, but I know that it’s needed in the future!

Numbers, Numbers, Numbers

    Throughout 2nd and 3rd quarters, I’ve learned things I thought I’d never understand. I’m not one of those people who absolutely hate Math. I have a love-hate relationship with this particular subject, but hey! It’s needed in the real world. I’m not bothered with how difficult the lessons are because I know that I would definitely use them in the future. I’ve been having a hard time catching up with Math nowadays, but I’m enjoying it so far! [The picture above shows a part of what I’ve learned this year.]

The 3 M’s

    For this 2nd and 3rd quarter in Statistics and Probability, I’ve learned how to get the mean, median, and mode of a grouped data. (The 3 m’s!) It’s honestly pretty difficult to create something for this subject because you need past data or collected data already, but I’m excited to learn more! Without statistics, it’s going to be difficult to make decisions from a data that was collected. For example, you use statistics to get the average grade from a test so you know how the students are performing!

    The pictures below basically summarize what I’ve learned so far.

 

Pre-Algebra Problems

     For Math, I am doing Pre-Algebra. It’s definitely tougher than the past math topics I’ve been doing, but Teaching Textbooks, my math textbook, makes it so much easier. I’ve been using Teaching Textbooks for quite a long time now and I’m pretty used to the problems that I answer. I decided to answer math questions out of my math textbook, so I could get used to other problems. Thankfully, I’m doing better than I expected. 

Algebraic Equations

     These are just some of the exercises I had to do for Pre-Algebra. Most of my friends say that pre-algebra and algebra are really difficult, but I’m currently having fun! This is just basic Pre-Algebra, so it will definitely get more difficult once I level up to Algebra. I’ll just try to have as much fun as I can in my school years even if it’s very stressful.

Earning Money Isn’t Easy

   Now that I’m Grade 7, math is definitely more difficult to do. I’m doing Pre-Algebra right now, but the first few lessons are about topics I’ve already learned. Why am I still doing them? Well, Teaching Textbooks is a math program from Grade 3 to High School that has a CD and textbook for each level. I learn by listening to the lesson first and then answer the questions. Its style is to review past lessons first before continuing to new lessons, so that the students don’t forget. I find it fun because it sounds like the teacher is right beside me.

   The topics I decide to focus on and make a word problem about is money and decimals. Here it is: 
   I am saving up for an international camp I want to go to next year. I don’t know exactly how much it will cost, but I know it’s around P100,000. If I end up having some extra money after the camp, I’m going to put some in the bank and the rest I will use to buy things I want. By the way, the solutions are in the picture because I have no idea how to do them on Blogger. The questions are below the picture.

   1) If the camp will be in twelve months, what is P100,000 divided by 12? 
       The answer is: P8,333, but the 3 just repeats and repeats. That is called a repeating number! To be          sure, I rounded it off to P8,400 to have some extra money. 
   2) If I spend around P85,000 for the camp, how much will I have left? 
       The answer is: I will have P15,000 left! 
   3) If I decide to go shopping, I will spend P1,000 on white t-shirts. Then, I will spend P212 on dye.          Afterwards, I will spend P546 on some DVDs. I will decide then to go to the bank and deposit              the rest in my bank account for future use.  How much will I end up spending? How much will I            put in the bank?
       The answer is: I will spend P1,758 and deposit P13,242. 
   4) If I decide to sell tie-dye shirt for P250.50 each and I will sell six in a month. How much money            will I earn? 
       The answer is: I earn a total of P1,503! 
   5) I will to continue the business for a year and I will sell eight in a month. How much do I earn? 
       The answer is: In a month, I earn P2,004. In a whole year, I earn P24, 048. 
   I am saving up, but the problem is that I don’t have a business or a job yet.  I basically rely on my allowance.  I am hoping that sooner or later, I get to come up of a business! Thinking about this really just says: “Money just doesn’t grow on trees! You have to get a job, earn, and make a business. It doesn’t come to you easily.” 
       

Chances Are…

   Do you ever play games with your candy? Well, I sometimes do with Skittles which is my all-time favorite candy! Recently, I played a game with my pack of Skittles. It’s pretty much related to my lesson in Math. Probability. The problems I made involving Skittles and probability are below and I even solved it myself! 
   Problem #1: There are about 56 Skittles in one regular pack. 13 of them are green, 15 are orange, 8 are yellow, 11 are purple, and 9 are red. What’s the probability of getting 5 green pieces the first time? What’s the probability of getting 1 orange piece the second time? Suppose you ate the first few candy pieces. 
   Solution #1: 
           First time:   13 + 15 + 8 + 11 + 9  =  56 pieces 
                        5 pieces 
                        Favored outcomes:     5 
                                                        ——-
                        Possible outcomes:    56 
             Second time:   1 piece 
                        56 – 5  =  51 
                        
                        Favored outcomes:   15
                                                      ——–
                        Possible outcomes:   51 
                                      5                  15              75
                                  ——-      x    ——-   =     ——- 
                                     56                 51            2,856 
   If we’re picky with the colors/flavors of Skittles, we can see that we have a pretty small chance of getting the colors/flavors we want! We should just be content with what we get! If we’re super choosy with what we want, we may just end up with nothing. {Contentment is being happy with what you have. It’s a very important character trait we need.}
