Veititi’s Maths Learning Story


At Porirua College, there are 220 boys.  132 boys choose to wear a lavalava.
E.J says that this percentage is because Porirua College students have a strong Samoan identity.
Do you agree that the percentage E.J worked out is enough to show that Porirua College has a strong Samoan identity?
Maybe you're confused about maths?. Well, I am too.
When I was reading this problem the first idea that popped into my head was to divide the whole number which was 220 to find fifty percent. I was trying to find out what percentage 132 boys is equal to.
Well, the first obvious thing was to draw a number line, so I drew a number line to show the different percentages. Here’s how I solved it.
As you can see on the number-line. I knew that half of 220 was 110 students so that was 50%.
Then I did 110+22=132 because 22 is 10%. I knew that 22 was 10% because I knew that 100%=220 so I took away the zero from 220 which equaled 22 which was the 10%. Or 220 divided by 10= 22 students.
To find 60% I worked out 110+22=132. So I worked out that E.J was right.
I found out that finding half of the total number is helpful because if you had a problem like this you could use the same strategy as me or different.
My next steps are to make sure I fully know the problem by reading through it again and again until I can explain and justify the problem and understand it.
Life is a math equation. In order to gain the most, you have to know how to convert the negatives into positives.

It’s not about being the best, it’s about improving your personal best and not giving up. Beating my personal best is a goal I have achieved this year, even if I struggle, I never give up. The first thing we did was rest/play. While we were resting/playing we watched others to see what they did to be good. We also cheered people on and encouraged them to keep on trying. Encouraging was something I did all day. I was a brilliant cheerleader. I enjoyed encouraging my peers so that it would motivate them to achieve their personal best. In a way it made me feel as though I was responsible for a little bit of my peers accomplishments and happiness. Only a little bit. Then we moved on to discus. I think I tried my best to get silver even though my goal was to get gold but at least I tried. I had to learn how to hold a discus before I threw it and to throw it in the right direction. I think I improved on my real throw because I took the teacher’s advice. The teacher's advice was to

Art Learning Story.

What is surrealism art? Surrealism began as a philosophical movement that said the way to find truth in the world through the subconscious mind and dreams. Surrealist works often show familiar things in unexpected or impossible ways. Art is not my thing. But I stepped out of my comfort zone and had a try. I was really good at relating to others because I asked for advice on what colors I could use. In my art, I combined a guitar and my face. It shows that music is my passion. My hair has patterns in it which show my culture which is Samoan. The K.C skills I used was self-managing. I focused and chose the right people and the right place to get my art done. I didn’t distract other people and I shared my ideas. I was struggling with the equipment because it was too thick like the pastel. So I knew that my next steps were to not draw small patterns or else it will be hard to color. My advice for those people who don’t like art is to not be shy and just draw. Don’t be
