Math Reflection (the most boring blog post in the world!)

Hello everyone! My name is Tan and I’m a student in 6B. I’m almost going to be in 7th grade. My math teacher is Mr. Fedley and he is from Austrailia. He loves teaching us and is a very nice teacher (I guess…)

imgresimgres-1imgres-2

In this semester, I have learned lots of fun and interesting things. But I don’t mean it for all the work. We learned are measurements, probability, integers, patterns and algebra and the exam.

This semester, we did a lot of textbook works and taught people math. We did some mathletics and paper worksheets.

I enjoyed doing the textbook works. LOL!! Actually I enjoyed the works he gave us because that made my tests results become better. I also enjoyed asking questions because Mr. Fedley always explains it in a understandable way.

This semester the integers unit was kind of hard because it had a lot of patterns and that is one of my weakness. Also I could’ve done better on the exam because I didn’t expect my marks.

Next year I want to be able to get a full mark for my report card. So I will ask a lot of questions even if Mr. Fedley won’t be there. Which is kind of sad 🙁 I will try to focus harder on algebra because it’s my strength. I hope to see you Mr. Fedley again angain and thank you for teaching us these past years. Have a safe trip!

Is It Probable?- Math

For this blog post, I will introduce to you about probability! Probability is very important in part of math and also in life. This might be kind of helpful although it might be different from a real teacher teaching you.

First of all, I’ll introduce 5 different chances of an event occurring.

1. Impossible: it WILL NOT happen

2. Unlikely: not likeley to happen

3. Even Chance: 50% chance of occuring

4. Likely: quite likely to occur

5. Certainly: will occur or happen

These words can really help you tell what amount or how much cahnce their is in words.

Next, I’ll give a real word example for each.

1. Impossible: It is impossible that I will run around the world in one second.

2. Unlikely: It is unlikely that a monkey will jump in my car and hit me with a banana.

3. Even Chance: It is an even chance that there will be snow falling as the weather cast said.

4. Likely: It is likely that I can hit that ball and make a homerun.

5. Certain: It is certain that I will really hungry (because I’m already hungry)

Ok finally, I’ll use a fraction, decimal and percentage to represent each different event.

1. Impossible: Fraction- 0/100 Decimal- 0.00 Percentage- 0%

2. Unlikely: Fraction- 25/100 Decimal- 0.25 Percentage- 25%

3. Even Chance: Fraction- 50/100 Decimal- 0.50 Percentage- 50%

4. Likely: Fraction- 75/100 Decimal: 0.75 Percentage: 75%

5. Certainly: Fraction- 100/100 Decimal- 1.00 Percentage- 100%

Well that’s the end for this and I hope you learned something about probability. This might’ve been a little hard to understand becuase of me, but it could be useful. Bye 😀

Our Introduction to Measurement (Mr. Fedley is getting on my nerves!!!)

Today in math class, we’re making a blog post to introduce to you guys about measurement. At first let me introduce the unit question and the area of interaction. The unit question is called “How can we calculate using measurement” and the are of interaction is that we’re going to relate to during this unit is “Environment”. I think that measurement can be used in many environments because you have to be able to measure things in our daily lives. (e.g. supermarket: you need to measure how much you can buy with the money you already have.)

Moving on, I’m going to tell you three questions for this unit. One is a factual question (a fact), one is a conceptual question (how to do something) and one is a debatable question (something which may have more than one answer). The factual question for me is “What is a nanometer?”, the conceptual question is “How do we convert kilometers to tons?” and the debatable question is “Is it better to use centimeters or meters?”

These are where you can find measurement in our daily lives:

The clock is one thing that measures something. A clock is an helpful thing that measures time in seconds, minutes and hours. Wow, isn’t that really new to you?

The air conditioner and heater is also a thing that measures something. It measures the temperature of the room and can measure in °c (celsius) or °f (fahrenheit). You might notice that there’s “Bearded Perry” sticking his head out on the side.

The ruler is another thing that measures something. The ruler can measure the length of an object in centimeters, meters, inches, etc. Again, if you might notice there’s the same Perry on top of the ruler.

As you’ve now seen from these pictures and learned few new things about measurement, let’s talk about how to find the area of a square or a rectangle. To find out the area, you need to multiply the length times the width. There’s an example shown below.

Screen Shot 2014-03-02 at 9.30.31 AM

In this example of a rectangular shape, the length is 7cm long and the width is 16cm wide. To be able to find the area, you need to do 7cm × 16cm which equals to 112cm2. But, it’s most important to not forget the 2 at the right side top of the cm sign. If you don’t write 2, it will just show the length of the shape and won’t exactly show what the area is. So that’s how you can find the area of a square or a rectangle. That might’ve been a great explanation, right? Well I hope it was.

Ok so next is like the same, but it’s the area of a triangle were going to find. For a triangle you need to multiply the base (bottom of triangle) times the height and divide it  by 2. Here’s an example of it again.

Screen Shot 2014-03-02 at 10.04.47 AM

In this example of a triangle, the base is 10cm and the height is 9cm. When you multiply those two, it becomes 90 and when you divide it by 2, it turns into 45cm2. The reason why we divide it by 2 is because a triangle is a half of a rectangle in which it is the rule. The 2 on the top of the cm sign is the same with the rectangle, although the way you try to find the area is different with the way of doing the rectangle.

This might be getting exhausting, but I have to also explain how to find the volume of a 3D square or rectangle. Below is an example of it.

Screen Shot 2014-03-02 at 10.23.43 AM

This example is a 3D figure of square. To find out the volume of it, you need to multiply all 3 sides, length, width and height. For this one, you need to do 6cm × 6cm × 6cm. Then you can get the answer of it which is 216cm3. At the top of the cm sign for this, you need to put a 3 to show it equals to the volume. This is what you need to know mostly about it and it will be really useful in our life.

For next, I’ll talk about what’s good and bad about measurement. I think that measurement is good for measuring lots of things like time, temperature and distances. But I do think it’s also bad because you can find out how much you weigh. If your someone that eats a variety of junk food, you might find out that you weigh a lot and get shocked. It could make you eat more and more which eventually will lead you to getting way fatter than before. I bet that’s not what they want.

In conclusion, I’m satisfied with having measurement in our life. There are many advantages that help us do things much better and can give us a convenient time. So after all I think it’s something essential for everyone in this world.

Comparing Decimals

For today in math class, we went outside and measured the length of 3-4 objects.

unnamed

Water Fountain

This water fountain has a length of 89cm×35cm. In km, it’s 0.089×0.035.

unnamed-1

Skateboard

This skateboard has a length of 70cm×29cm. In km, it’s 0.007×0.029.

unnamed

T.V.

This T.V. has a length of 125cm×30cm. In km, it’s 0.125×0.003.

I think that converting decimals into different units of measurement weren’t that too easy and simple. It’s imprortant to get the right length of measurement and not to make that much mistakes as possible.

My Refelction of Semester one in Math!!!

In the first semester, we learnt lots of things, everything relating to math and nothing else other than math 😀

I especially remember the time when we became into young teachers and thought our students how to find out the answer to addition, subtraction, multiplication and devision of fractions. Me and my group created a video to show and explain how to devide fractions, made up worksheets and games. I think doing these work made it easier to understand the devison of fractions. What I’m going to tell you next doesn’t have to do anything with math, but it was fun and exciting so I’ll tell you. What was fun was that we got to play games between our math class. Now we don’t play games that much, but in the start and middle of the first semester we played a few games so that we wouldn’t get tired of doing math and we could concentrate properly on what we needed to do. One of the games were called “Celebrity Heads” and we had guess who the person was that was written on the board. Also, liked and enjoyed getting candies from Mr. Fedley. On my birthday, which was December 13th, Mr. Fedley gave me dozens of chewing candies, chocolate and lots of more sugery stuff. Those candies all ended up in my stomach and made me hyper, jumping up in the air for a cupple of minutes. But after school was over, I went back home and slept that night pretty early than always. I used so much energy that I couldn’t stay for that long not sleeping in my bed.

Well afterall, I think math is one of the interesting subjects to learn (just kidding….ok, maybe a little) and I like Mr. Fedley for being a super awesome teacher. Isn’t that a compliment, Mr. Fedley, right?

Our Introduction to Fractions

Did you know fractions are fun? That’s what Mr. Fedley says, but I say it’s boring.

Well let’s talk about fractions. A fraction is a way of showing a number or a piece of something which is not a whole number. A fraction usually has a denominator and numerator. The denominater shows total number that will make up a whole number or the pieces of something. The numerator shows the number or pieces that we have at the moment. You can find where the numerator and denominator go in a fraction down.


As you can see up at the picture, fractions can also be seen in real life. Look at the delicious piece of bread. Doesn’t it look so good? If you are smart in math, especially in fractions you’ll notice that I have a half of a full piece of bread. This can be written as 1/2 in a fraction, 1 as the numerator and 2 as the denominator.

I didn’t know what to do for a hard fraction so Mr. Fedley helped me chose something and it ended up to be a collection of rocks. Very very special rocks in fact (just kidding). So in the case, there supposed to be 40 rocks together, but there are only 7which I don’t care. In a fraction, this is written as 36/40. Here’s what I need to say. I think that collecting rocks are a really bad hobby.

Here’s an incorrect fraction.

You can see that there are three unevenly sized pieces of leaves that are lined up. Two of them are normal sized but, one is little sized. It probably might appear on you as a family of leaves, the two as the mom and dad, the little on as the child. This can’t be showed as 1/3 though there are three pieces of leaves because one of them aren’t the same size as the other two.
