# My Unit 9 Math Reflection

During this math unit, I was pretty good at finding the area of 2D shapes, and also finding the volume of 3D shapes. And because I double-checked, I only got 1 silly mistake! I wrote 5 centimeters instead of 5 inches in a problem in which I had to find the height of a prism from it’s volume and the area of the base of the prism. I thought that this unit was relatively easy, but I struggled with finding the area of scalene triangles, but when I figure it out, I thought it was actually quite simple.

I think that during this unit I was best at plotting points and connecting points on a coordinate grid, finding volume of 3D shapes, and also finding area of 2D shapes. I think so because I got all of the problems in these categories correct. I also think I was food at plotting reflections of figures on coordinate grids.

I found experimenting with coordinate grids really fun, especially ones with 4 quadrants. There were a few math pages where we plotted sailboats in different quadrants, plotted reflections of sailboats, and even made new sailboats from the original sailboat. Those were really fun because I really like experimenting with coordinate grids. I also thought the open response, where you have to explain how you solved the problems was really fun because I like writing long explanations, and you had to find out if you can get some tiles on a countertop without overlapping, getting off the countertop, or leaving extra space.

Anyways, I thought that this unit was really fun because I liked playing with coordinates, and also finding area.

# My Unit 8 Math Reflection

During this math unit, we learned all about mixed numbers, multiplying mixed numbers other things related to fractions. I thought that this unit was exceptionally fun, especially converting fractions to percentage and multiplying fractions. I also really liked doing math extensions like working on Khan Academy.

On this unit, I was very good at multiplying fractions, converting fractions into mixed numbers and also doing mixed number word problems. I was good at them because I knew how to do them already, but it was still really fun to do them! Adding and subtracting mixed numbers were also easy, but I thought they were harder than multiplying decimals because you had to convert to common denominator on adding and subtracting but you don’t have to for multiplying decimals. We also converted amounts of things out of other amounts into percents, which were really fun. We had to do everything in simplest form though, which was slightly annoying because you had to convert every time.

On this unit, I was bad at listing fractions that had denominators in order from least to greatest because I take a long time to get a problem with them right. I should have used the guide on the math test, but because I didn’t, I got a slight mix-up with a problem.

I also really enjoyed doing the oral test, which included finding common denominators for numbers, percents of numbers and also multiplying mixed numbers. The oral test was slightly boring though, because it takes a long time to do one problem because you have to wait for the whole class to finish before you move on.

Anyways, I really enjoyed this unit because it was enjoyable and challenging, but also quite easy. So I think that this unit was really awesome!

# My Student Led Conference

Last Friday, we had a student led conference, which is like a parent conference, except it’s led by students! I had to create a keynote that showed my learning to my parents, which was quite fun to do. I also had to find pieces of work that I worked on during the year, and I also had to talk about my goals that I set at the beginning of the year, and set new ones for the last weeks of school. Boey and I sort of worked together because we gave each other ideas for what to do.

Mainly, I talked about what I’ve learned this year, I also talked a lot about having the oppotunity to have a blog, and more importantly, a school issued iPad, at such a young age. I also talked about my goals. My original ones were to make 1 true friend and to double check my work, which I often fail to. I achieved these goals, and is set 2 new ones, the first one was to learn 5 more complex ideas of physics, but I would like to know more especially about quantum physics. The other one was to talk to people in a respectful tone, which I do pretty well.

The conference was an overall success in my opinion because I showed my learning in a variety of subjects by showing videos I made, tests I took and my various journals. I also enjoyed just showing how school was like to my parents! I hope we get to do that next year!

# My Unit 7 Reflection

Last Friday, we took the unit 7 math assessment, and I thought I did quite a good job on it. It was a pretty simple unit about negative numbers, adding and subtracting negative numbers and graphs. I don’t really know how graphs and negative numbers relate, but I guess they do!

Anyways, I think my strengths during this unit were creating line graphs, adding and subtracting negative numbers to positive numbers, and adding and subtracting negative numbers to negative numbers. I thought these were my strengths because I can do them really easily. And I can do them really quick. But sometimes I get confused with the fact that a negative number has to come after in a subtraction problem to reverse the symbol. For example -8 – 7 is -15, while -8 – -7 is -1. So I made some silly errors with that.

I also made some silly errors on my tests, 3 to be exact, but that’s better than most of my tests. And I got all proficients, which is a pretty good. Mrs. Huiet said that you couldn’t get any exemplary because there was no way to show your more complex thinkings on this unit’s assessment, so all proficients was technically the best score you can get.

Anyways, this was a really fun unit.

# Graphs

During this math unit, we learned about all kinds of graphs, and it was one of the challenges on the student challenge to make a graph. So here is a graph on the approval ratings of picking your nose. I know it might be silly, but I thought it would be worth a shot! Enjoy this graph!

# Global Events

In my life, I’ve been lucky enough to be part of a few global events. Such as the World’s Math Day, The Haiyan Relief Effort and a project that was not exactly global, called the Bali Service Learning Project. In this post, I will describe these three events.

On the World’s Math Day, I did challenges against players from all over the world! From people in Laos to Latvia, from China to Chad, we all did challenges on the World’s Math Day website. I won around 72 rounds against kids younger, and older than me. I almost won every round I did because they were simple problem! I really suggest you check out the website. Here is the link for World’s Education Games, which includes similar games for other subjects: http://www.worldeducationgames.com

For the Haiyan Relief Effort, I participated in a Walk-A-Thon. Where people donated at least 10 RMB for people in our school to walk laps in the school sports field, the ECLC department also baked cookies and sold artwork for the disastrous typhoon that ruined many lives. I have a blog post about the Walk-A-Thon, and for the Bali Service Learning Project, which I will talk about now!

The Bali Service Learning Project was a series of assignments from our teachers, to make items to help children in Bali that only go to school once every week. I made sets of videos with me showing a picture and asking what it showed. I then told the answer. I hope the children in Bali are using those sets, but I don’t know if they are.

Well, that’s it for this post. I hope you’ve enjoyed it!

# Unit 6 Math Reflection

Here is my reflection for unit 6 of math.
In this unit’s assessment, I only made 1 silly error! I was surprised I only had 1! Double checking my work, worked! My silly mistake was subtracting instead of adding when I had to add some fractions.
This unit’s open response was quite simple. I had to make up a family with 6 people in which the average age was 24 years old, and we had to have ourselves in this family. I used a father, a mother, two siblings, me and an aunt. I got a 4 on the open response and I think I did quite a good job explaining things.
On the oral test, I got everything right, it was quite simple, and it was a short oral test, it only had around 15 questions, unlike the usual oral test, which has at least 20.
Sorry for this post being short, but I don’t really have that much to write about this unit.

# My Unit 4 Math Reflection

This unit, I improved on double checking all my work and double checked every problem on my test, the test became really messy though, because I used pen above my pretest. I will double check everything on another sheet from now on, so it is not as messy.
For this unit, I need to work on dividing decimals by full numbers, and I will work on that by writing intermediate decimal division problems on a sheet and solving them, and also download some helpful apps to work on dividing decimals. I will start by working with decimals on the tenths and hundredths places, and will work until I can divide decimals with the tenths, hundredths and thousandths places.
I was good with three and four digit division and I loved using the partial quotients method because with the traditional method you had to estimate, but with partial quotients you don’t really have to think and the chances of accuracy are higher.

# Math Unit 3 Reflection

We just finished unit 3 in math! This unit was all about geometry and was very fun. We learned about tessellations, angles, shapes and many other very interesting things. Read it to know about the wonderful geometry unit!
During this unit, I did a lot of work with geometry. We measured angles, made tessellations and did a lot more stuff. I think I’m really good at measuring angles and recognizing angles because I almost never get trouble with them. I also think I am good at drawing tessellations. Because all the tessellations I drew were real tessellations. But until today, I thought tessellations could only be made from regular polygons. I was wrong. Because famous tessellations creators like Escher created them from circles and strange shapes.
I really liked this unit and it was very fun. And I really hope that we have another unit of geometry. I learned new things like what is a scalene triangle, and I also learned that the angles of a triangle added up together was 180 degrees. We really did a lot of things that we didn’t do in previous geometry units.
