Math is something that I need a lot of help on. This year, I felt like writing about math really helped me with my actual work in math class because I was describing and thinking about math a lot harder than I was in math class. Math is something that I struggle a lot with and sometimes I have to go into my math class early for help or stay after school.
My seventh grade school year has taught me a lot, and I am glad that I came here because I really feel like since I started writing about math my job in math class has become a little easier. It did make me work a lot harder and think a lot harder too, but I really learned a lot more just from explaining it. I think explaining what you do is important because it is another resource for answers and "intelligence." I don't really know how to describe it. All I know is it's one thing writing and doing the math in your brain than it is speaking and orally explaining how to do and work with math concepts and numbers. I am thankful my teachers made us do this project because I have learned at least 40% more than I would have if we didn't blog each monday on math!!! Sometimes, the work really is worth it. :) Just sometimes.
P.S This is my last Math Monday Blog :( !!!Have an awesome summer everyone! See you next year!
Humans see math everyday you'd think they'd know it better! Well, I am a failure at math. I work hard and have an A but sometimes I get so lost! This year linear equations were really easy and so was area but moving from Algebra to Pre-Algebra is tricky. In Pre-Algebra, everything is review which probably makes you think "Well she's an idiot!" In Pre-Algebra, I really struggled with word problems. They just didn't seem to click. I kept going in and talking to my teacher about it but his door was always locked. The next morning I'd mention my attempt to come in a work with him but again I found myself sitting outside his door because it was locked. It's quite frustrating really. Finally, I went home and asked my mom for (more and more) help.
This taught me that when there is a problem to not just sit around and do nothing. I need to put effort into my work and study. My mom once told me, "You can NEVER study enough." At first I thought, "Uh huh, sure I can. Whatever." but my mom was right. You can never study enough. There is no limit. The more you study the better your grades are. Plus, it's never to late to fix a bad grade. What I am saying is, don't procrastinate or wait 'till the last second. Do what you can when you can. Chose grades over fun because there is always a time for fun. They are all hard lessons to learn that I have learned really well. The better I work the better my grades get. The better you work the better your grades get. Learn the lesson now, make you decision now. It's easier to make your choice now because when the time comes, you won't worry or stress because you know what you have chosen. Even if you failed you last 7 test, you can always make some impact on your grade. Never Give Up.
Happy Monday and welcome back everyone! I am in a great mood today because I got 15/15 on my spanish test! Studying really does work! Anyways, today we will be talking about negative numbers and when we see and use them in real life.
Negative numbers are numbers to the left of zero on a number line. You'll see negative numbers with negative signs that look like this... - . For example, here is negative eight, -8. Negative eight's absolute value is positive eight, +8, or 8! Negative numbers are used to tell how less of something you have or how far away you are from zero in a negative way. For example, we use this today... when you're scuba diving three feet away from the surface of the ocean you're -8 down. If you go to the bank and owe 25 dollars.... that's -25. Negative numbers aren't that hard when you think about it. Just remember that they are always to the left of zero on a number line and they have negative signs!!!!!!!!!!!!!!
Welcome back and happy Monday! I hope everyone's weekend was fun and will talk about mine later on Free-Write Friday. Today we are going to "discuss" how to solve the equation "2x-7=15." Here, we go...
#1 Figure and Define.
2,7, and 15 are all digits
- means we are going to subtract
"x" is just a variable. It could be any imaginable number.
#2 Solve (Now that we know what everything is)
2x-7=15
YOU HAVE TO GET THE VARIABLE (x) ALONE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
So, subtract 2 from each side. 2-2=0 and 15-2=13
Now we have x-7=13
#3 Finish it off
Since 7 is -7 in this case, we will add to get zero (negative plus positive is zero if its the same number)
-7+7=0 and 13+7=20
Now we have x=20
#4 Double-Checker
Double check your work and make sure all your numbers are correct.
I've double checked my work and i know it to be true.
x=20
Horray!!!!!!!!!!!!!!!!!!!
Happy Monday everyone and welcome back to "Katie's Contemplations Math Monday Blogs." I hope everyone is ready to learn some math because today we have a great topic! Here's our main question... "How do you convert a decimal into a fraction?"
Let's start here...
.1 = 1/10 .01 = 1/100 .001 = 1/1000 .0001 = 1/10000
Get it? It's ok if you don't... I didn't describe it that well. Here, if you have .50 of a pizza, that mean you have 1/2. If you have .75 of the pizza, that means you have 3/4 of the pizza. Think about it this way, how much money is a quarter worth? That's right, 25 cents or .25. How many quarters does it take to make a dollar? 4, because 25 + 25 + 25 + 25 = 100. Now let's say that we put a decimal place in-front-of 25 so now it's .25. Add .25 together four times and get 1.00. So when you have a decimal in the tenth place, like this .2, put it over a ten... 2/10 (or simplified 1/5.) When the the number is in the hundreths place like this, .02, put it over one hundred... 2/100. Just work hard and ask questions and you'll for sure get it.
Hello and welcome to Math Monday! Today I will be attempting to write about converting fractions into decimals. It seems simple... and it is. One way to convert a fraction into a decimal is to divide. Here is a great example....
1/2 is our fraction... but we want a decimal. So we are going to divide...
1 divided by 2. Since one is smaller than 2 your answer has to be a decimal. .50 to be exact. Another way is to have a ratio... let's say for every 1 banana we get to slices of banana bread. 1:2. Now you can divide... 1 divided by 2. Again, since 1 is smaller than 2 you should get a decimal... .50, again.
If you don't understand somethings it is completely okay to talk to your teachers because they are there to help you. There are also tons of books for math if something doesn't make sense. Don't give up because that gets you nowhere. Stay pro-active!!!
Imagine you work at a restaurant, the best one in town! That means your restaurant is popular, and food disappears very quickly. Your boss hired you to make daily trips to the nearby supermarket and replace food. He sways you could use percentages or ratios for each meals ingredients, but expects you to be back in 3 hours. Can you do it? A percentage is like a decimal and a fraction which if your buying things... could be tricky to use. A ratio would be easier. Here's an example. On the dessert menu, banana bread is a popular option. 1 banana is used for every piece of banana bread baked. That means 1 banana is used in every loaf of banana bread... 1:1. A ratio would be easier to buy things. 10 bananas will give you 10 loaves of banana bread. If 4 grapes make glass of grape juice, 4:1, then how many would grapes would be used to make 4 glasses of grape juice. 16 grapes! Let's say you need 1 ounce of cheese for a small bowl of kids' macaroni and cheese. You buy 15 ounces of cheese! That means 15 bowls of kids macaroni will be served! As you can see, working in a restaurant can be tough. Working with ratios, well, that can be as easy as you make it! Just remember... 1:1 or 1 to 1.... are a couple different types of ratio formulas and all you have to do it look for the numbers then plug them in! Good luck!
We all know Pi is 3.14, and we all know circles are round. Well, you should know. How big is a circle? That is our main question today. We are trying to figure out how big a circle is or a circle's circumference. You find the circumference by multiplying pi (3.14) and the diameter. Lets say we know the radius is 3...inches. Our diameter would be 6 inches because the radius is half of the diameter. So multiply 3.14 and 6 and get 18.84. Your circle's circumference would be 18.84. It's really easy to find circumference,
Hello everyone! I'm back from my cruise in which I had a BLAST! I got to eat whatever I wanted, whenever I wanted, wherever I wanted. Speaking of food, I'm hungry... HEY PI! If you get that joke, well done. If you don't here's a clarification. Pie is a food, Pi is a number.

I've learned throughout the year I've been in school that Pi goes on for a very long time and my math teacher, Mr. Dorman brings Pi to school (3-14-13[15]) every year and in 2015, boy its going to be CRAZY for him! We normally use 3.14 for Pi, not the whole nine yards. "The whole nine yards" is an idiom that basically is saying, you don't need to do it all when you could o a little and get the same results.
Oh my goodness! It's been forever, literally since I blogged in "Math Monday" again! Well, lucky me I guess got the past 3 Mondays off and now I'm leaving for my Disney cruise on Thursday! Wow! I hope I can blog quickly. So today's topic is on linear equations. What question can you ask once you know the equation of a line? Well, you can always try plugging numbers in for "x." Just plug any random number in for "x" you could use 2 1/2 of 3.5768964729304819483 or -3. You could also ask, "how did I get this equation?" and work with your graph to figure it out. Things should go pretty smooth from here if you have a correct graph and table, otherwise you might want to look over your work. If you ever need help, your teachers and parents are always there. Your friend are always there too. It's sometimes even better if not only you, but your friend don't understand something because then you two can go about asking teachers together, and you won't feel so alone.
Lines, tables, and graphs are really simple once you get to know them. Seriously, you could get all "A's" on your tests only if you study and learn the simple formulas to them. Do you get that part? Do you understand? Do you see why we graphed y=3/4x +10 that way? If you don't do something about it. Do something so your grades and future aren't affected. Your life, is like a graph. Do you know how you want to graph you line?
