Fay’s Nines Reflection

This past few weeks we have been doing the Fay’s Nines problem. Here are some unique solutions:

As you can see, there are 3 columns of numbers. The units column equals 19, the tens column equals 18 and the hundreds column equals 8. But for this to work, you have to carry (starting from the units column), then it all adds up to 999.

When I started playing with this problem I was interested to see how many unique solutions their were. I tried to find different strategies to work out different solutions, but I was having trouble finding unique solutions fast.

At the end of the first session (during the class discussion) Sienna and I realised that the units column had to add up to 19, the tens column had to add up to 18 and the hundreds column had to add up to 8. Here is our working out for the first session.

To break this problem into manageable parts, I got one unique solution and then turned it into another one by moving the numbers around. But with that strategy, I only got 2 solutions with similar numbers.

I kept doing trail and error for two sessions. Then I realised that if I got one solution, I could get a lot more. I didn’t realise it at the time, but I could get 36 more solutions. So, to start off with I kept the same numbers in the units column, and shuffled the numbers around those ones. I found 20 solutions, but I had a feeling there was more. After Mr Henderson had told us that there were 36 solutions for each 3 numbers that were in the units column, I had a light-bulb moment. Because there are 36 solutions for each combinations for each 3 numbers in the units column, and there are 5 units combinations (that equal 19), you multiply 36 by 5 and that equals 180, which is the correct answer.

This problem was challenging because I didn’t understand the carrying. After Mr Hopper helped my understand, I kept trying to find the answer. But little did I know that I had to find the answer to a smaller problem. To find the number of solutions for each 3 numbers in the units columns. This problem was very challenging and fun, and I hope to do something similar in the future.

For my last passion project  of the year, we have to dedicate or target our passion project at a member of our family or extended family. I am going to create a short film about my sister, for my sister. In the film, there will be like a voice over behind the video. It will be like a letter to her.

I think that I will either use my phone or my camera to film with, exploring different angles and lighting. And to edit this film I will most likely use Adobe Premiere. If  Adobe Premiere is not working or I can’t figure something out I will use Movie Maker.

My project is targeted at my sister, Quinn. She is a big part of my life, and she has always wanted to be in my films. So, now she is the main focus in my film.

I am looking forward to seeing Quinn’s reaction when the whole movie is done, editing the all of the shots together, exploring the angles and lighting, looking at different locations to shoot at, writing the script and recording the voice over.

My film is inspired by this film:

I am so exited to see where my passion project will take my this term 🙂

For the past term I have been working on my Passion Project. And as I have been saying, I created a short film/montage of Noosa (where I went on my holiday).

I am pretty proud of the shots that I got, and achieved what I had originally set out to do. The finished product has come out mostly the way that I planned.

The whole experience was a success like the editing, the shooting, the planning, the lighting, the equipment supply, ect. The only challenge that I faced during the process was that THERE WAS NO SURF. No surf means no waves, no waves means no surfboards, no surfboards means no good surfing shots, but I’m not complaining. The weather was perfect all the time, it was amazing.

If I were to continue this project, I would probably learn more about different editing programs to use, or just editing in general. I could also learn more about the different angles for shots, when to use slow-mo, things like that.

Here are a few photos from Noosa:

 

Building Views Reflection

For the building views problem, we were given a tub of blocks to build a building out of. But as you may have guessed, this wasn’t any old building that we had to make. On the activity sheet there was a 4 x 4 grid:

Those squares were where we put the blocks. Below that, there were several problems. To solve those problems, you had to build a tower. Here is what one of the problems looked like.

Let me explain. As you can see, there is a 4 x 4 grid, the same as the building sheet. Basically, say if there is a “3” on the bottom left corner of the grid, you would put 3 blocks in the same place on your real grid. And if there was a “2” on the top right corner of the grid, you would put 2 blocks in the same place on your real grid. The aim of the problem was to draw the front and side view for that grid, by looking at the building you built. Like this:

The next step to this activity was to do the same thing, but to try and find the maximum and minimum amount of blocks that we could use to build the same building, without changing the views. My strategy for finding the maximum amount was to fill the whole bottom of the grid with blocks (but obviously not the slots that have 0 in them), and then see if we could add any extra blocks anywhere. For finding the minimum amount, I basically did the opposite of finding the maximum. Tried to take as many blocks away as I could, without changing the views from the front and side. After we competed either the maximum or the minimum we checked with our peers to see if they had the same answer as us, or if we could improve.

 

The most challenging part was doing building 5. That is because of the rules. It was the same as before (Where you had to build grid and then draw the side and front view) except you weren’t allowed to build it. So, you had to imagine what the building would look like.

What I have learnt during this unit is…

-That you should make sure to go back and check your thinking to make sure it all makes sense and is correct

-Colours can make a difference when your looking from different views or patterns

I really enjoyed this unit, and hope to continue something similar in the future.

My Self-Sufficient Space Station

For Mr G’s clinic in Inquiry, we got to choose where we thought would be suitable for humans to live in the future. I chose a self-sufficient space station orbiting earth. We got a sheet with information about each topic. Then were told to make a video log about why we chose that habitat, but Blythe being Blythe, she did something different. I did a news report. Here it is:

As I said in my last Passion Project blog, I am doing an artsy, montage video that explains my trip to Noosa (in Queensland) and what I did.

I have explored different editing apps such as imovie, pocketvideo and I’ve also experimented with the “time laps” and “slow mo” feature that is provided on the camera app.

I have not experienced any difficulties in my project yet, but I am prepared and ready for any problems that may occur during the process.

The next step for my is to work out what I am going to use to film. I am 99% sure that I will be getting a water proof phone case, for the shots underwater (and will just use my pgone for all other shots), or the other 1% chance is that i will hire a waterproof camera.

For my term 3 passion project I am planning to create a film. I about 3 and a half weeks, I am going on a trip to Noosa (in Queensland) and I am making a film about my experience, and how amazing it is. The film will be like an artsy, montage with music in the background.

To edit my film I am going to use the app “imovie”, and I am going to explore the different filters, speeds and clips. I am going to explore different styles of music that may or may not match with the film.

My film is aimed for people aged around 8-18, or for people that like travel diary entries. But overall anyone at any age could watch my film, and maybe hopefully enjoy it 🙂

I am most looking forward to the filming part of the process. Mostly because I know that I will love going to the places (like the beach, going on walks ect.) Overall I am very excited for the whole process and am looking forward to see how it turns out.

Here is the video that inspired this idea:

This blog post is going to be a reflection on making my skim board!

I originally set out to build a small surfboard, but then thought realistically about the decision. My dad suggested that I make a skim board. After he had explained what a skim board was, I agreed. I don’t think I could say that I completely achieved my goal, but I am definitely very pleased with the finished product.

Towards the end when I had to film me trying to ride the board, it was 11 degrees and it felt like we were in the middle of a tornado. It was very, very cold and sand was blowing on the back of our legs. The water was freezing.

When it actually started to get quite dangerous, we had to go and use the footage that we had, witch wasn’t much. I probably needed more footage, but it was very unlikely because of how cold, windy and dangerous it was. In the end, I stuck with what I had.

If I was to continue with this project, I would probably go and ride my skim board again and learn more about how to ride it and work it. Another thing I would learn if I continued was how to clean off the wax and things like that.

In my video, my dad rides my board! Will he be a pro,

Or will he be a flop?

Win At The Fair

The past few weeks in Project maths our class has been working on a problem called “Win At The Fair”.

On the first session of out new problem, we were introduced to a game board. Here is what it looked like.

(How you play: You put your counter on the “Start” tile, and roll two dice. Say if I rolled a 4 and a 2, my number would be 6. If you look at the tile at the very bottom of the picture, with the arrows pointing out of it, you will see numbers on the end of the arrows. They determine witch way I move my counter. If I roll 1,2,3,4 or 5, I move my counter left. If I roll 6, 7 or 8, I move my counter forward. If I roll 9, 10, 11, or 12, I move my counter right. You keep rolling until you land on a prize.)

My class played 117 games all together, and here is the data that we collected of how many people landed on what prize.

As you can see on the right side of the picture, we put $117 dollars in (because we played 117 games, each worth $1), and with the game board that we had, we put $213.40 out. We had a total loss of $96 dollars. Everyone decided that the money that went out, and that we lost, wasn’t good enough.

The next session we were told to create a game board of our own, and we could choose our own prizes and dice directions. Since this board was called the “Creative Board” we could include things like “Black holes” to make it harder for the player to get to the”Jackpot”.

As you can see, we have put two black holes in effective spots. We put the first black hole on the right of the “start” tile, because we figured that 1, if you rolled a number that turned you right then you would be eliminated, and 2, it is basically impossible to get to the $5 because there is no option to roll downwards. Think about it.

After that, we were told to make a board that would be enticing yet profitable. This board was called our “Official board”, and it couldn’t have any black holes or obstacles. Here is our “Official Board” data.

But our board didn’t always look like this, here is the process of what we went through to get this board.

Try 1 = $1,177.90 out and $1.18 average payout

Try 3 = $905.30 out and $0.91 average payout

(changed the $15 jackpot to $9)

Try 5 = $32.30 out and $0.53 average payout

(changed 10 to 50, $9 to $10)

Try 7 (final)= $422.50 out and $0.42 average payout

(Changed 50 to $10)

Our board was profitable because there was only 1 “jackpot” and the rest of the prize tiles were mostly cents and $1.

Our board was enticing because the first thing the player saw was the $10 jackpot, and they knew it was possible to get. Also, getting a $1 isn’t so bad.

Here is another snip of our finished board.

As my passion project T2, I decided that I was building a small wooden surfboard. As I was discussing this with my dad, he suggested a slightly more achievable idea. A skim board!

A skim board is like a surfboard, accept you skim on the water in the shallow.

So far, I have collected the wood, cut out the shape and started sanding. Along with the skim board, I also have a short video on what I am doing, and the process of making it. Of course, to add some comedy I have decided that I will be trying the skim board after we have finished making it (P.S I have never skim boarded before…).

Some new things that I have learnt:

-How to use an jigsaw (electric saw) (with parental help and supervision)

-How to check what size wood to use (see if the wood is flimsy or strong, you need something in between)

-How to trace a skim board

-How to investigate what shape to use.

So far the process have been completely successful and enjoyable. I am excited to see what problems or challenges await.

The next step of my skim board process is to finish sanding. Sanding is one of the most important parts, but also takes the longest. After that we have to bend it, stain it, add my decals, and add a clear waterproof sealer.

I am so happy with my idea and what I have accomplished so far, and can’t wait for what comes next!

Here is a small cliffhanger of my Passion Project video!
