How to deal with those pesky little graphs:

10.
a) Yes, you can. You can buy 2 flowers.
b) There would be one on 2, because you can buy that amount

















11.
a)( 60, 2)
b) 60 = $60 invested
      2 = Simple interest
c) The amount invested goes up by 20
The interest multiplied by 20 = amount invested
d) 90. 180 / 20 = 90

















12.
a)










b) The functional pattern is the length .cm multiplied by 4
The perimeter cm is adding by 2
c) Yes, you can have a measurement that has a decimal (e.g. 3.5)
d) Yes, it's linear. The graph data is shown in a straight line.

Alyssa's Pay it Forward

Part 1

What is "Pay it Forward". To complete this part please edit and revise the paragraphs that you wrote after watching the movie. 

 Pay it Forward is a movement, where you get to do random acts of kindness, and you ask for nothing in return. Pay it Forward is an amazing way of helping people, and spreading out the cause. When you do this you don't ask for money or a payment in return, you tell them to "Pay it Forward", or help other people instead. It's a really simple process that you do, just to help random people, or people that you know.

 

Part 2

What was your Pay It Forward act of kindness?

Why did you choose this activity?

Who did you help?

What did you do?

When did you do you act of kindness?

I actually did two acts of kindness. The first thing I did was that I gave toys to the Christmas Cheerboard, for kids who will probably get nothing for Christmas. I chose to do this, because I realized that while we're getting tons of expensive gifts, there are kids that get nothing. In doing this, I got to help kids have a nice Christmas, and I also got to help the Christmas Cheerboard fill up their boxes. I did my act of kindness on November 24th, in the afternoon.
My second act of kindness was that I gave Thank-You letters to my grade 5 and 6 teachers. I chose to do this because those teachers helped me understand that I could become a leader, and an amazing citizen. I helped my teachers light up and feel very proud of themselves. I did my act of kindness at lunch, on November 29th.

These are the letters I gave to my teachers. I couldn't get pictures because of privacy reasons.

This is the certificate I got for helping out!

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Part 3

How did your act of kindness go?

What Happened?

How did you feel?

How did the person or people react?

Did you ask the person or people to "Pay It Forward"?

How did they react to your request?

If you did not ask the person to "Pay It Forward" how come?

My first act of kindness went really well. I went to the warehouse, and gave one of the workers my toys; she was really nice about it and happy as well. I felt really awkward at first, but then, I felt very happy and I began to feel very gracious. The worker was surprised to see that I was donating toys, and not an adult. I told the worker that I hoped that the toys would go to a nice family, and that they should continue doing what they do. The worker reacted very surprised, and thankful.

My second act of kindness went very well, also. I went to my school and gave my Grade 5 teacher her letter. As I was doing so, I feel very amazing, and there was kids watching, so I felt proud as well. My teacher actually started crying, and she was very happy; in fact, she hugged me and told me that I was one of her favourite students. I told her, in the letter, that I wish that she would Pay It Forward as well, and help people.

Part 4

Why is the idea of "Pay it Forward" important?

Has your act of kindness made a difference? 

The idea of Paying it Forward is very important. That's because we usually don't think about other people, or help people expecting something in return. We all need to learn how to become gratuitous people, and we need to learn that we do not always need something in return.

I think my acts of kindness made a difference. That's because, now, some kids will get some Christmas gifts from "Santa", and because my teachers can now smile and feel proud and content.

Alyssa's Fraction Scribepost

Hi! Today in class we talked about how to properly divide whole numbers by fractions and vice-versa.

First off, we used words to describe or work out the problem. We used "How many groups of ____ go into _____?" or "Share ____ equally with _____ a group".
Then we talked about using the number line. I'll use 6÷½(one half).You divide the number line into your fraction, into halves for example. Then count how many times it goes into your number!

We then talked about reciprocals (I think they're the easiest!). I'll use the same question to provide and example. You take the "denominator" and make it into 1 or a whole (it's usually just the fraction inverted!). Then use that reciprocal and multiply the "numerator" by it.

Here's the hard part. A fraction divided by a whole number. 
Here, you use the "Share ____ with ____ equal groups" sentence. 
I'll use a quarter divided by 3.
 



















Here is a link to a simpler explanation on reciprocals, just in case you didn't read all of this. Here it is
And here is a video from a teacher explaining this!

Sorry if this post was too long! I just wanted to show everything we learned about in class! Have a good night!


My Test Corrections 

Here are my corrections for the first part of the test.
(I'm sorry for my extremely awful pictures)

 I realized that in the test, I used common denominators right away, for some reason.
























And here are my corrections for the second part of the test.

Fractions by Alyssa

Alyssa's Proportion Post

Part 1 

Please define

• ratio- a pair that compares two different numbers. e.g. 5:23
• rate- a pair that compares two different different numbers that have different units. 25km:hour
• proportion- a pairing that shows that two rates/ratios are equal. 5:12mm = 10:24mm

Part 2

1.  5 hours to travel 360 kilometers is about _72__km/h.   
    
2. Emma saves 28 cents of every dollar that she earns.  Emma earned $75 last week.  How much money did Emma save? .28 x 75=21. Emmy saved $21

Part 3

What are the three ways you can prove that equivalent ratio statements are true?
3/4 = 12/16  or 4/9 = 16/32

1. 3x4=12  4x4=16 (Top method)
2. 3/3=1--1x4=4 12/3=4--4x4=16 (Side method)
3. 3x6=48/4=12 (Cross method)

4/9 = 16/38. This does not work, so the fractions are not equal. 4x4=16. 9 x 4=36

Part 4

Find a video about using proportion and embed it in your post.  Make sure you select the small size of the video. (Bonus Marks if you make your own video about proportion and embed it)

Task 5

We are starting to engage in discussions about social justice.  What do you think about this image below.  Use the link to copy it into your post.  Then answer the questions

http://www.concurringopinions.com/wp-content/uploads/2011/10/CrimeInAmerica2.jpg

1. Does this seem fair? Not at all.
2. With what you know about proportion look and read what is in the image above.  Does it seem just and fair? No.
3. Why have you made this choice? The CEO has stolen 3 billion, and is going to jail for 4 months, but he should have gotten a longer time, because he has stolen a huge amount. The homeless man stole 100 dollars, and is serving way too much time in jail. The times are unfair, and they do not seem right for the amounts of money they both took.
4. What would you have done if you were the judge? If I were the judge, I would have given them a just amount of serving time that went with the money they stole. The times might as well be switched.

How tall are these trees, and how tall would five trees be if they were put end to end?

Answer: The average height of a 10 year old kid is 4.25 feet. He could fit about 3 times. So, 4.25 x 3 = 12.75. The trees are approximately 12.75 feet tall.
 You'd then multiply 12.75 by 5 to get 63.75.
