Mean maths reflection
Dear Mum, Dad and Miss Hinds,
In class, we have been learning about the 3 triple m’s, which is mean, mode and median, but today, we have mostly focused on the mean. So here is a reflection of what I have learnt and things that are all about ‘the mean’.
1. What is the mean?- The mean is the average. So you get a collection of numbers, add all of them up, and divide that number by the total amount of numbers in the set.
2. How do you find the mean of a data set?- Add up all of the numbers in the data set that you are given and divide this by the total amount of numbers in the set.
Eg: 5, 3 2, 10=20=20 divided by 4, (because there is 4 numbers), =5. So the average is 5.
3. What does the mean of a data set tell us?-The mean of a data set tells us and shows us the average of a data set and shows us one number that represents the whole data set.
Data and Graphs gamaes
Dear Mum, Dad and Miss Hinds,
For maths, we had a range of websites that were maths graph games, and we had to play each one. So I have taken some screenshots, and to look at the screenshots, click on the link at the top of this post.
For the first game, we had to interpret bar graphs, and answer some questions according to the bar graph. In that game, I didn’t really learn one specific thing, but that game helped me to get a better understanding of graphs, how to answer questions from the data in a graph, and to basically see if I was good at maths or not.
In the second game, I had a whole range of questions and data, and I had to choose the correct graph that would best represent the data and information. In that game, it helped me to understand how to represent specific questions in a specific graph.
Boat People
Dear Mum, Dad and Miss Hinds,
In class, we have been learnng about the boat people, who they are, what they did/do, and some stuff about them. Then we had to answer some questions personally, here they are…..
How do you feel about boat people coming to Australia?
I feel that they should be allowed to come and shouldn’t. They should be, because like jazzy said, we would do the same, and they shouldn’t because you never know what their like and what they can do to people.
How do you feel they should be treated?
They should be treated like how you want to be treated, because they are just like us, but escaping from a bad situation. Even if they are not normal, you still have to treat them with patience and respect.
What is your opinion?
My opinion is that we have to care for them, and help them. If they are thieves, or something, report them to cops but I think that you should treat them with respect?
12 Chip dice game, Maths Homework 2013
Dear Mum, Dad and Miss Hinds,
For homework this week, we have to play a chance game. I couldn’t take a picture of one of the games that I played, so I created a table, and did it in word. Click on the link to view. 12 chip dice game
My questions:
Is there a number that is being rolled constantly?
Well, sort of, if you click on the link, you will see that 11 was rolled the most. I rolled 11 3 times, and so did my mum. I am sure as to why 11 was occurring the most, but I guess it was just lucky.
Is there a number that isn’t being rolled very often?
Well, again, if you click on the link, you will see that 2 and 3 weren’t being rolled a lot, both my mum and I only rolled it once. Obviously, none of us rolled a one because you cant roll 2 dice, and get two numbers that equal one, and there isn’t a dice with a zero on it.
Have you changed the position of the counters?
Yes, I moved them around because as you know, 2 and 3 weren’t being rolled a lot, and 11 was being rolled heaps, so I put none on 2 and 3, and I put 4 on 11. It worked. I haven’t put the other games that I played don my blog, but when I played the other games, 11 and 9 were being rolled a lot, and 2,3 and 10 weren’t really being rolled at all.
Explain the game, and what you were required to do
Well, first of all, you had to get a partner. Then you get 2 a4 pieces of paper, divide that into 12 boxes, and write a number in each box between 1-12. Then, you have to get some sort of 12 counters, and once you have them, place the counters where ever you want, you can have none in one box and more then 1 in one box if you like. After that’s all set up, one person rolls the dice. Add your two numbers that you rolled together. So, say if you get a 2 and 2, that equals 4, you take a counter off the 4 box if you have one on there. You continue this method until one person has removed all the counters of the page. But, you have to record. So draw a Tally. In that tally, you must have the number, the tally, the total, the experimental probability and the theoretical probability. If you click on the link, you will see how you have to draw it out. 🙂
What strategies did you use at the start of the game
Well, one strategy that I used at the start of the game, was not putting any counters in the 1 box, because you cant roll 2 dice that equal a 1.
Did you change your strategy as you repeated the game?
No because obviously, you still cant roll a 1 no matter how many times you played. But I figured out a new strategy, which was to put less counters in the box that wasn’t being rolled out.
What numbers did you place the least most counters on? Why? Did this change as you played more games?
Well, at the start, I didn’t really know hat numbers weren’t going to be rolled out apart from one. But as I played more games, I realised that 2,3 and 10 were hardly coming up at all, so I put less counters on them, one game, I even put no counters on each of them and it turned all right, to be honest. Sorry you cant see the other games.
What did you notice about the chance of rolling certain numbers? Are there numbers that are most likely to occur then others?
I noticed that the chance of rolling a 11 often was highly likely and I noticed that rolling a 2, 3 and a 10 very often was highly unlikely. So 11 was almost certain that it would be rolled more often if I played even more games.
Theoretical Probability
Dear Mum, Dad and Miss Hinds,
In my independent learning journal, I have a chance worksheet. I have done that so now I am just answering some questions. Here they are.
Explain what is meant by theoretical probability?
Theoretical probability is/means the probability that a certain outcome will occur. To find the theoretical probability you have to divide and times by 100. So if my fraction was 5 over 32, 5/32, I would do 5 divided by 32. and times that answer by 100. That answer equals 15.62.
Explain what would happen after each trial if the block was not put back in the box.
Well, if each block was taken out after each trial, there will be a less number of blocks, so there is a more equal chance for each coloured block to occur the most. But because Miss Hinds put the block back in, she was most likely pulling out the same block more then once. So what I think will happen is that each coloured block has more of a chance of winning or coming closer to the winning block because Miss Hinds takes the blocks out.
What do you notice about the chance of pulling a red block out of the box? Has it changed?
I notice that the red has occurred the most. It has changed because this time round, red didn’t occur the most, yellow did. I hope I answered this question right, didn’t really understand what it was asking but this is what I did.
Is this a independent or a dependent chance experiment?
This is an independent experiment because the recent block that was pulled out did not affect the other blocks and there outcome. I hope this is right, but if its not, well, I had a go, :).
Chance spinner
Dear Mum, Dad and Miss Hinds,
What did you discover?
I discovered that out of 10 trials, green was landed on 6 times, and that was expected. I also discovered that orange and pink were landed on the least amount of time, and blue was landed on once more then orange and pink.
What worked
The things that worked was that green occured the most because the reason why we did these spinners was to see if green was landed on the most, and it worked and it was successful.
What didn’t work
Nothing really didnt work. Everything went to planned. So green was landed on the most, and because orange and pink had a less amount of space, they occured the least.
Was your spinner successful, why? Why not?
Yes, my spinner was successful because like I said one million times, lol, green was landed on the most, and because I gave orange and pink a less amount of space, they were landed on the least amount of time, and that made it successful.
How could you modify/ change your spinner to allow you to get more accurate results?
ps: In class, I will eventually upload my pic of my spinner, no stress.
Fair/Unfair chance game
Sorry, it is landscape, so when you look at it, look at it as a potrait, :0. Also
I didnt have time to put another pic, so when I have time, I’ll do it.
Dear Mum, Dad and Miss Hinds,
In Class today, we got with partners, and my partner was Joshua, and we made a chance game. Here is some info about my game.
2. Josh’s and my game is pretty simple. So you have 2 dice, and you roll both dice. If both dice equal a 6, 7 or a 8, you move left. If both dice equal a 2,3,4 or 5, you move up and if both dice equal a 9,10,11 or 12, you move right, and you keep going until you land on one amount of money. Then it is your partners turn. To keep scores, draw up a tally, and right down your amounts of money, then do a mark next to the amount of money that you landed on. We chose to design it that way because the other game board we used was effective but we thought we could make it better. So we thought of a few ways, and our way wasnt effective, because we one half the amount of money that the school one. But it was very fun.
3. Our way wasnt effective, because we one half the amount of money that the school won. I think the reason why it wasnt effective was because on the first round, most of our dice equaled a 2, 3, 4 or 5, and they were low scores, so we moved it around and what we did was sort of wrong. But it was very fun and Josh and I worked pretty well from my perspective.
4. Yes, altogether, our rolls equaled 46 dollars, but because we charged a dollar or a dollar fifty, I forgot, we won only half. So they raised 30 dollars, and we got 16 dollars.
Homework week 2
Dear Mum , Dad and Miss Hinds,
This is my homework task that we had to do. We had to choose a situation, what the problem was, what the solution was, and how I adjusted.
When I was at karate, I was practicing some techniques with my friend, but I got hit, really hard, that it made me cry, sort of. So I ran to the bathroom to dry up my tears . My friend Alyssa, and my dad came up to me, and made me feel better, because Alyssa had got it to and she explained to me that it will just make me tougher, and that’s how I adjusted. After that I went home. This made me think of and realise how really lucky I am to have my family and friends there to be by my side.
Addition and Subtraction maths game
Dear Mum, Dad and Miss Hinds,
Above this and at the top, you will see a link to the screenshots of the game I played. I played an addition and subtraction game. It helped me to write in the sum answers quicker because I would lose a life if I was slow and it made me learn to never give up!
