Last Monday, we learned how to divide fractions.

There's 2 ways of doing this.

Elementary or Junior High

If you don't know how to do the Junior High, read & view this scribe post!

There was no negatives in the equation so it's a positive.

'How many times can 3 go into 12?' = 4

Now listen up, this part is important.

If 1 number is negative, it's like this :

(-12) ÷ 3 = (-4)

But if 2 numbers are negative, it's like this :

(-12) ÷ (-3) = 4

So here's the SIGN RULE.

2 negatives = positive answer

1 negative = negative answer

It doesn't have to be 1 or 2 only, odds & evens too.

1-3-5-7-9-11

2-4-6-8-10-12

John's Pay it Forward

.:: Pay it Forward - JMQM ::.

----------------------------------------------------------------------------

Part 1

----------------------------------------------------------------------------

What is "Pay it Forward".

"Pay it Forward" was a "word" that - a kid would go around doing good deeds to others without recieving anything in return. So this kid would help 3 people. Then each of them would help 3 other people which is now 9 in total. Then each of those 9 people will help 3 other people and so on.

 

Part 2

----------------------------------------------------------------------------

What was your Pay It Forward act of kindness?

For my "Pay it Forward", I send a bunch of my shoes which is over 10 shoes that were Derrick Rose, Michael Jordan, and other NBA players. The other act of kindess that I did was shoveling the whole Ashburn Street.

 

Why did you choose this activity? 
I chose to send my shoes to Salvation Army because I don't really use some shoes so I just decided to send it to them. And for the shoveling, I saw some people in my street going slow because there was ice all over, so I decided to shovel the snow and remove most of the ice.

 

Who did you help?

Well I helped a bit of the needed people and hopefully most people that live in Ashburn Street.

 

What did you do?

I sent my shoes to Salvation Army & shoveled the Ashburn Street.

 

When did you do you act of kindness?

I did the sending of my shoes on November 27th and shoveled on November 28th - 29th.

Part 3

----------------------------------------------------------------------------

How did your act of kindness go?

My act of kindness' went fine.

 

What Happened?

I send my shoes to Salvation Army and shoveled Ashburn's snow.

 

How did you feel?

I felt great in the inside because I knew I was making a BIG difference, even if what I was doing was small.

 

How did the person or people react?

The people reacted thankful and givingful, but of course I did not accept the gift they were giving to me.

 

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

I told SOME people to "Pay it Forward" and also to check it out.

 

How did they react to your request?

The people reacted surprised and overwhelmed because it was a very cold week to shovel. And sending NBA shoes like Jordans, they were PROUD! :D

 

Part 4

----------------------------------------------------------------------------

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

The "Pay it Forward" is important because everywhere, people are always in need and most of us people that have something that we do not use, someone out there can enjoy that gift. Giving.

 

Has your act of kindness made a difference?

For the people I have provided with more supplies and comfort, yes.

My Test Corrections :

John's Proportion Post

Part 1 - Define

Ratio

A comparison of two different types of numbers

Ex - 128 students out of 11 teachers = 128:11

Picture Example

Rate

A ratio that is comparing two quantities of different units

Ex - I bring in 38 wooden sticks inside my home and it takes me about 10 minutes

Picture Example

Proportion

Equation showing two ratios that are equal

Ex - I have 10 cows and 20 dolphins = 10/20 or 1/2

Picture Example

Part 2 - Solve

1) 5 hours to travel 360 kilometers is about _____km/h.

5 ÷ 5 = 1 & 360 ÷ 5=72

A = 72km/h

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

1 x 75 = $75 & 28 x 72 = $21.00

A = $21.00

Part 3 - Improvement

3/4 = 12/16 - 1/2 = 6/8

4/9 = 16/32 - 1/2 = 4/8

Part 4 - Video Example

Task 5 - Discussion

1) Does this seem fair?

A) $3 billion = 40 months. $100 = 15 months. 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?

A) For the CEO, it's $75,000,000 each month. The homeless man, it's around $1.30 each month.

3) Why have you made this choice?

A) It seems pretty obvious that it's not fair at all. Comparing $75 MILLION to $1.30 cents? It's clear that this isn't fair or just.

4) What would you have done if you were the judge?

A) Let him go. He stole a $100, told and probably and obviously was taken from him or he gave it back, so it's all good.

Bonus Question

Q) How tall are the trees?

A) First, I went onto paint, copied and paste the guy, and stacked them together on each other and see how many of them are needed so the guy is high as the trees. My result was I had to copy and paste 2 of them which is making 3 of them, and there was a little space above, i'd say ¼. I guessed that this guy is about 14 years old so then I went to the internet and searched the average height of a 14 year old teen. So what I got was that the average height for a 14 year old teen was 64 inches tall. So I calculated - 64 x 3 = 192 - so i'm guessing the tress are 192 inches tall.
