Today in class we learned how to model multiplying integers, how to say them in words, and the different types you can multiply by, such as (+)x(+)=(+), (-)x(-)=(+), (+)x(-)=(-), and (-)x(+)=(-). These are the examples in class:

The other example we used in class was....

As you can see there are different ways to also say the multiplication statements for integers.
Here are 4 different questions, but they have 4 different ways to state these questions.

Now here are my 4 questions that I decided to do. I picked each of the different types so hopefully you can understand better. (I will only do the modeling!)
Also if these are very easy numbers, I apologize because I just took the first ones I saw that I haven't done yet.

I hope you understood more about multiplying integers!

Tina's Pay it Forward

Part 1.
What is "Pay it Forward"?
I believe that the term "Pay it Forward" is when someone helps people, then those people help more people, and this process keeps continuing. Pay it forward has a powerful meaning behind it. If we continue "pay it forward", the world will slowly change into a better place, possibly a place where people care, where people have homes, clean water, healthy food, and education.

What was your Pay It Forward act of kindness
My pay it forward act of kindness was volunteering at Winnipeg Harvest with Mikee, and Arizza.

Why did you choose this activity? 
We chose to go to Winnipeg Harvest because we wanted to help some families and people that can't afford food. We wanted to help the people, the families that can't go to a cupboard or the fridge and just take out food like us.

Who did you help?

Hopefully we have helped the less-fortunate families and people who might have been suffering from starvation get some food.

What did you do?

When did you do you act of kindness?

I did my act of kindness with Mikee and Arizza on December 8th 2012 at 9:00 A.M- 12:00 P.M.

Part 3.
How did your act of kindness go?
My act of kindness went very well. It was a very fun experience, I hope I can go again with my friends!

What Happened?
We first filled out a form, and then we went to take a tour around Winnipeg Harvest with our tour guide, Shelly, she explained about what goes on around Winnipeg Harvest. After the orientation, we stayed to volunteer until 12:00 P.M. We spent 3 hours sorting Potatoes but the time went by very fast. While we were sorting we saw Katherine! When it was almost time to go, we went to get some Hot chocolate and a snack! Then after we finished drinking our Hot Chocolate and eating our snack we went home. It was a very fun experience!

How did you feel?

I felt very good about myself because I feel like I have helped many people, even if I only did something little.

How did the person or people react?

The people that I saw had smiles on their faces, I think they had smiles on their faces because they were happy that some students donated some of their time to help.

How did they react to your request?
They didn't really react because I didn't tell them to volunteer, but I think they were happy that some kids actually volunteered.

Did you ask the person or people to "Pay It Forward"?
No, I didn't tell the people to Pay it forward. because I felt that they were already paying it forward because they were also volunteering on their own time, but I did tell them about the project we were doing.

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

I didn't tell the people to pay it forward because I felt that they were already paying it forward because they were also volunteering on their own time, but I did tell them about the project we were doing.

Part 4.

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

Pay it forward is important because it helps people be more aware of what's happening to others around the world. Pay it forward makes people realize that not everyone has healthy food, a home, clean water, education and other things that we are fortunate to have in our lives. Pay it forward makes others want to help change the world to make it better place. Pay It Forward is also important because even just a little act of kindness we do can have a big effect on others, and slowly, we can make the world a better place.

Has your act of kindness made a difference?
Yes, I think my act of kindness made a difference. Even though what I did was small, it still made a difference in some less-fortunate people's lives.

Today we had to do page 227 in the textbook. I'm going to be doing numbers 1, 4, and 9. I will also be showing how I got the answer.

 Question 1- Anna divided 5/6 by 1/2 and stated that the quotient is 5/12. A) What was Anna's mistake? Answer- Anna's mistake was that she didn't flip the second fraction, which is called a reciprocal. Like this:

B)What is the correct quotient? Use a diagram to show how you know.
Answer- First I'm going to estimate, then say what the question is asking in words, solve the answer, then use a diagram.
 


Now that I finished that, I know the answer, which makes it a bit easier to draw the diagram. I'm going to make the fractions with a common denominator. Like so-




















Now onto Question 4.

A) Does 2 1/2 divided by 1 1/2 equal 1 1/2 divided by 2 1/2?
Answer- I believe that this question is asking if both of the questions have the same quotients or not. Which the answer is no, because the first question is 2 1/2 divided by 1 1/2, the answer is 1 2/3 (5/3), the second question is 1 1/2 divided by 2 1/2, the answer is 3/5, therefore the answer is no.

B) If the quotients in part A) are not equal, how are they related?
Answer- They are related in a way, because they have the same numbers, such as 2 1/2, 1 1/2, 1/2. They also in a way have the same answer, just flipped up and down. Like this-

Now my final question, I will answer, Question 9.
Divide.
A) 3/4 divided by 4/5.
Answer-15/16

B) 1 2/3 divided by 2 5/6
Answer- 9/17

C) 12 divided by 3/4
Answer- 16

Those are all my questions, I hope I helped you understand, even if it was just a little bit!

My Test Corrections.
On my test my mistake was drawing a diagram for 1/4 divided by 1/3.
So here's my correction for that question.

Everything Tina knows about Fractions

Tina's Proportion Post

Part 1. Define

Ratio.
A comparison of 2 quantities that have the same 
unit of measure. For example..








































Rate.
Rate compares 2 quantities measured in different units. For example........

Proportion.
An equation that states that two ratios are equal. For example...........
Part 2. Answer/Solve

1. 5 hours to travel 360 kilometers is about 72 km/h.

This is what I did to solve this.



















Another Way I did it was like this: 


2. Emma saves 28 cents of every dollar that she earns.  Emma earned $75 last week.  How much money did Emma save last week?

This is how I solved it.

Another way I solved it was like this:

Part 3. What are the three ways you can prove that equivalent ratio statements are true?

1. 3/4 = 12/16 

2. 4/9=16/32.
This statement is not true; is not correct, because 4 can go into 16, but 9 can't go into 32. Because 9x3=27, and 9x4=36, So then there is no 32 in the 9's time table. So the 32 should be 36.

Here's a picture of what I mean.

Part 4. Video

















Task 5. http://www.concurringopinions.com/wp-content/uploads/2011/10/CrimeInAmerica2.jpg

Does this seem fair?  No it's not fair

With what you know about proportion, then look and read what is in the image above.  Does it seem just and fair? No, it's really not just and fair. Because the lady gave him 3 stacks of bills, he only took a 100 dollar bill and returned the rest of the money. In proportion it would be like this: $/Sentence in prison, 3Billion/40Months = 1Hundred/180Months. If you look at it you will notice right away that it is definitely not fair, because you can see the big difference in the numbers. 

Why have you made this choice? Because he only took a $100 bill, and got 15 years in prison. This wasn't 1st degree robbery because he didn't have a weapon. Plus it was only because he was homeless and poor! He even turned himself in because, he said his mother didn't raise him that way! While the other guy stole 3 billion dollars and only got 3 years in prison!

What would you have done if you were the judge? I would've sentenced the guy who stole $100 to 1 month and 3 weeks in prison, because even if he turned himself in he still 'stole' $100. And for the guy who stole 3 Billion dollars, I would put him in 17 years in Prison, because he stole a lot of money.


Part 6. Bonus Question!

Im Choosing The Kid in the woods.

My Own Question is: How tall are the trees?

My Answer to that is : The boy looks about 13 yrs old. An Average boy height at that height is about 5 feet. Then I used my thumb to see how many of the kid it would take to reach the top of the tree. About 3.5 kids would be needed about his height to reach the top. After that I multiplied 5x3.5 which is 17.5. So Then I rounded up, So 18. I think the trees are approximately 18 feet tall.
