Allison Concepcion's Scribe Post: How to divide integers

There are many ways to divide integers some ways will work some cannot. Dividing integers is a bit more complex than multiplying integers but the same sign rule applies. A positive and a positive equals a positive. A negative and a positive equals a negative, and a negative and a negative equals a positive.

What does ÷ mean? This symbols means you are sharing _?_ into _?_ equal groups in this case lets just say you are sharing (+8) into 2 equal groups. When you are dividing integers the numerator is what you have ( you have 8) and the denominator represents how many groups there are (you have 2 groups) e.g.

8- What you have
2- How many groups you have

First off, if you are dividing two positives, there are two possible ways to show your work.

(+8)÷(+2)= 4

Step 1: Have (+8) and have 2 groups.
Share (+8) into 2 equal groups.

Step 2: Now you share (+8) into two equal groups
Your answer will be 4

Now that you've figured out how to show your work in one way, here's another way of how to show your work.

You are asking yourself, how many groups of (+2) are in (+8)?

Step 1: have your (+8)











Step 2: Now, ask yourself how many groups of (+2) are in (+8)
There are 4 groups of (+2) in (+8)
Your answer is 4

If you are dividing a negative and a positive integers, try to use the same method as before.

(-8)÷(+4)= -2

Step 1: Share (-8) into 4 equal groups






Step 2: You share (-8) groups into 4 equal groups
Your answer is -2

 
Method 2: How many groups of (+4)  are in (-8)?
You cannot do this method because there are no groups of positive 4 in negative 8.



 X







 This time you are dividing a negative by a negative and also see if one of the two methods work.

Method 1: Share (-8) into (-4) groups.
It is not going to work because there is no such thing as (-4) equal groups.

X







Method 2: How many groups of (-4) are in (-8)?

Step 1: Have your (-8)

Step 2: Now ask yourself, how many groups of (-4) are in (-8)

                  ↓                                    ↓
             
         1 group               +            1 group             =              2 groups

         Your answer is 2.


Now, you are dividing a positive by a negative, same rules apply try the same two methods to see if one of the two methods work.

(+8)÷(-4)= -2

Step 1: Share (+8) into (-4) equal groups

X





You cannot do this method because there is no such thing as sharing positive 8 into negative 4 equal groups. 

Method 2: How many groups of (-4) are in (+8)?

                X



Once again you cannot do this method because there are no groups of (-4) in (+8)

Since none of these methods work there is another different method that we can use which is called Multiplicative Inverse. Multiplicative inverse is basically the opposite of dividing so instead od dividing to figure out the answer you have to multiply to get the answer.

Step 1: Ask your self (-4) multiplied by what will equal (+8)?

(-4)x (? ) =(+8)

Step 2: If you figure out what the missing number is that will be your answer.

(-4)x (? ) =(+8)
(-4)x(-2)= (+8)

-2 will be your answer.


You cannot show this method by using a model you can only show this method by using multiplicative inverse.

Allison Concepcion's Pay it Forward

Part I

 

                           Pay it forward is any act of kindness, for this act of kindness you try to help out 3 people who you think need help or just anything you think would be kind to do for them. EX: a homeless person who needs food or you can help an elder person by carrying their heavy groceries. Now that you've influenced the person to pay it forward now, they can pay it forward to 3 more people and it spreads out like crazy. In the movie Trevor helps 3 people who he thinks need help. An example would be when Trevor tried to help the homeless man by feeding him and taking care of him. Now that Trevor paid it forward to those 3 people, the 3 people pay it forward to 3 more people and the acts of kindness spreads out.

 

Part II

 

                       My Friends and I paid it forward by shoveling peoples walkway and the sidewalk. Doing so we raised $40.00 for shoveling our neighbor's walkway. Of course we couldn't take the money for our selves so we decided to donate it to the Philippine typhoon relief. We made our neighbors cards telling them that we couldn't accept the money so we gave it to the Philippine typhoon relief and left them candy canes in their mail box.

We also gave out candy canes with little cards telling them about pay it forward and brightening up their day, we designed kitchen ware items and gave them to our neighbors, and we also gave teachers treats and cards saying how nice they've been and for taking care of us.

                             

                                        We chose this activity to do because we were all capable of doing it, no one was left out and not one person couldn't do the activity just because they don't think they can do it. We are all capable of doing acts of kindness and helping each other out. This activity was fair for all of us we did everything together and no one got to do more or less. This showed us that working together as a team all of us can get it done.

 

                                We helped our neighbors by shoveling their walkway and by shoveling the sidewalk so it's easier for them to walk. During this activity we raised $40.00 for shoveling our neighbors walkway. I remember that one of our neighbors said that she told us that she was a family therapist and she has seen the movie Pay it forward and loved it. She paid it forward to us by giving us the $20.00 but of course we couldn't accept the $40.00 we raise so we decided to donate it to the Philippine Typhoon Relief. We left them cards and some candy canes saying that we appreciated the money they gave us but couldn't accept it so we donated it. We didn't know that we would receive $40.00 for shoveling their walkway but it made us really happy. We've noticed that even one little act of kindness can brighten up someone's day which happened to us. That day we were so happy just by helping people in the neighborhood it was very fun.

 

               We did our act of kind on December 29th and December 30th 2013.

Here's a video showing our acts of kindness
 

 

                                        

 

 

 Part III

 



I think our act of kindness was well done and I'm not saying that it's perfect but still it was a pretty fun experience. What happened was that we didn't have a chance to shovel all of our neighbor's walkway because it was very cold outside but we successfully completed two walkways and in return we raised $40.00. The kitchenware we designed didn't go as planned because the design kept rubbing off and as much as we tried to prevent the design from rubbing off it wouldn't work. Speaking of the kitchenware we tried calling the Betelstadur Housing Co-op ( an elderly home) on 1061 Sargent avenue to notify them that we were going to drop by and give them the kitchenware. Sadly they didn't want to take chances so they needed information about what we were doing, of course we didn't know Mrs. Wilson's cellphone number or Mr.Harbeck's number so we couldn't give them the kitchenware items. Another problem we faced when we were doing our act of kindness was when we couldn't make enough  heart shaped candy canes in time before Pam or Ceci left because they had to leave early so we had to make less heart shaped candy canes than we wanted to.

 

When I first thought about all these activities that we were going to do I said to my friends that they were crazy. Doing all of these activities in less than 3 days to do everything but when we began to do it, I thought it'd be hard to accomplish but it was quite easy. I was surprised of how we managed to do everything so simply especially when we had some difficulties since we worked together as a group that's why it was so simple. Ever since then, I felt like I was a better person just because these small acts of kindness. Seeing the neighbors smiles on their face told us that we have become great people for better or for worse.

 

The people that we helped were very happy like we made their day by shoveling their walkway. They were freezing because they had their doors wide open talking to us and giving us their money. For the rest of the day we didn't get much of a reaction because we decided to give notes and shovel their walkway without giving ourselves attention. Some people were probably out of their house or just sleeping but they main thing was to pay it forward not to bring attention to our selves and showing off.

 

While we were shoveling our neighbors walkway, they gave us money for helping them but of course we weren't doing it for money we were just simply paying it forward. So we told the kind lady that we didn't do it for money we were just paying it forward. She responded by saying that she seen the movie before and  she loved it. She also told us that she was a family therapist helping families sort out their problems and I think that's how she pays it forward by helping one another. Since we didn't take the money we decided to donate it to the Philippine Typhoon Relief and we told our neighbors that we did so and that we appreciated them giving us the money.

 

 

Part IIII

 

The idea of paying it forward was important because it can save peoples life or change the way they've lived. It's basically doing even little acts of kindness could be noticed and be spread on and on and on  until everyone in the world has done something to help someone or change something. Doing great little things can mean so much to a person.

 

 

I hope that our act of kindness opened up their eyes and made them very thankful because there is no other better feeling than helping someone who was in pain, or who had difficulties and many more. I hoped it changed the way they look at the world and think that it's just not a world full of strangers, its a world full of people who have the ability to make a difference.

 



 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Ceci's Pay it Forward

PAY IT FORWARD 

2014 :)

BY: CECI ZHONG

    JOANNA BABADILLA

    PAM JOSEPH

    ALLISON CONCEPCION

Part 1 

What is pay it forward?

 Paying it forward is a way to thank our society by helping other people, we can do some simple things that can help others or make their days. the boy named Trevor in the movie <pay it forward>, he came up with the idea of paying it forward, it starts with one person to help 3 three other people to do something big , and these 3 people have to help 3 other people, and more...it spreads out, more people will involve to this activity, you can make a huge difference to the world just by doing something kind to others. These actions does not have to be huge, but just do something that can make them feel happy and warmth.

Part 2

What was your pay it forward act of kindness?

Our pay it forward act of kindness was to shovel the sidewalk of the street and walkway for our  neighbors; designing kitchenware items for our neighborhoods; giving out treats to teachers, putting candy canes (made in heart shape) with a small messages into people’s mail boxes and also we had also given a box of candy canes with a letter that has information of pay it forward to a day care.

Why did you choose this activity?

We choose these activities because its something that are helpful to them, and can make them happy. Shoveling the street snow, and neighborhoods walkway were very helpful to them. Because its hard to walk on thick cold snow, also it wastes a lot of time just to shovel a small area of snow, we did it for them so, they don’t have to come out to this very cold weather and shovel when they should have a rest or have a nice warm dinner with their family. We designed kitchenware items because, kitchenware items are useful to family, every family needs kitchenware items efforts that were putted in the designing shows how much we care about them, I am sure that you can feel the warmth when you look at it. We had given treats to teachers because we really want to thank them, they had helped us a lot, not only knowledge for school also knowledge for life. We dropped off candy canes with a small messages and information of pay it forward into peoples mail boxes, the main point of this activity was making their day by a candy cane and a small message, also we want them to know and understand what are we doing and what is pay it forward, so they can spread the information of pay it forward to other people or they can get started on pay it forward. The last thing that we did was giving a box of candy canes with a letter to the day care because, we wanted to let the teachers know what are we doing so they can teach kids about pay it forward, so in their heads, they have some ideas of pay it forward, candy canes also made them feel happy!

Who did you help?

We helped people around us, 

Teachers, 

Kids

Neighborhoods

(etc)

When did you do your act of kindness?

We did our act of kindness on December, 29th and December 30th .2013  

here is  our video ...

            

Part 3

How did your act of kindness go?

Our act of kindness was not going like what we had planned, a lot of thing are not as easy as we thought of, but we still tried our best to do it. Things that we really can’t do it such as, giving kitchenware items to the elderly home, we could not do it because they have to confirm with our teacher, but we don’t have our teachers’s number, so we decided to give these kitchenware items to our neighborhoods. Also it was hard for us to shovel snow in a very cold day for more than 2 hours. Even though our actions were not easy but when we see their smile, everything worth it .

What happened?(how did the person or people react? Did you ask them about pay it forward...)

Our group decided to go to one of our member’s house (BABADILLA) to work on our project. On the first day, we went to Walmart to buy all the materials that we need, then got back to Joanna’s house to get our shovels and get ready to shovel the sidewalk and neighborhoods’s snow. We planned two people to shovel and two people to take pictures and videos (rotated). When we were shoveling the first neighborhoods houses, a woman came out ans she was very appreciated what we did, she said “thank you” so many times, and gave us 20 dollars, we told her that we are doing this for “pay it forward” we don’t want to receive her money, when she heard we said we were doing this for paying it forward, her reaction was very surprised, she told us that she loves the movie pay it forward, but she wants us to receive the money so she has a chance to pay it forward. And after we received more money, we decided to donate these money to the Philippine Typhoon Relief. After we shoveled snow, we started to work on writing cards, designing kitchenware items, rapping gifts, and editing, it took us a lot of times to do it, after we go out again and dropped off candy canes, kitchenware items to people’s houses and mail boxes. 

How did you feel...? What did you learn?

I felt very satisfied and happy after I helped people and made them smile. Even though I always knew that its a good thing to help other people but I don’t experience it a lot, I didn’t really understand the main of helping, after I did this project, i will never ever forget the moment when people had a big smile on their face when they received our help, it was so beautiful, their smile lift up the whole world, at that moment you feel like the sun is shining on you, you can feel the heat even though you are standing in a temperature of -40co, you feel like you are the happiest person in the world! While working on this project I had learned how teamwork is very important because, if we don’t work as a team, we don’t cooperate each other, we would have a lot of disagreements, we wouldn’t be able to finish this project.

Why is the idea pay it forward important ?

Pay it forward is important because it makes people become more selfless from selfish, more positive from negative and it lets you experience the fun of helping others. while we were doing these act of kindness, we learned to be more selfless, we learned to think about other people, our community and the whole world. We work harder and have a big smile rather than complaining. Also we had fun while helping others.

Did your act of kindness make a difference?

I think our act of kindness did make a difference, because I could see people were touched by our action, this little “touched” might not make a big difference but it will spreads out, it will grow bigger and bigger, stronger and stronger.

Acknowledgment...

Thanks to all our grade eight teachers for always there to help us !

Thanks to Joanna’s family for letting us to work at their house!

Thanks to Joanna’s cousin who helped us to buy materials and helped us to make the kitchenware items!

Allison's Percent Post

PERCENTS

What does percent mean?
Per(out of) cent(one hundred)

Why 100%
Its 100% because its just right it's not too high and not too low of a number. It's a number that can be easily seen. The percent sign
( % )
 represents 100 the line equals the 1 and the 2 circle are the 0's.

There are improper fractions or top heavy. What it means is that the numerator (part) is greater than the denominator (whole)

205/100 represents
205%, 205 out of 100, and 2 wholes.

What does....
10% means? 10% means 10/100, 1/10 (equivalent fraction)
50% means? 50% means half, part/whole, 20/40 or 50/100
25% means? 25/100 1/4 (one quarter)
1% means?  1/100 1 out of 100
100% means? all, whole, everything, 40/40 or 100/100


Representing Percent's: 180%, 0.6%, 12 3/8%

a) 180%

b) 0.6%

c) 12 3/8%

Combining percent's



When you are working with money you're expecting to have discounts, sale prices, and total price with taxes. 

Discount-what you save
Sale price- what you pay

When you are trying to find the sale price you take the regular price and subtract it from the discount to get the sale price.

                                     Regular price- Discount= Sale price

When you are trying to find the total price including taxes you add up the items or item you bought to find the total price. Now you have to add the tax to the total price. If the tax was 13% you would add 13% to the total price which is the all, the whole, the 100%
100+13= 113
You then divide 113 (the total price including tax) by 100.
113 ÷100=1.13
 The 1 represents the total price and the 13 represents the tax.            Now you multiply 1.13 by the total price (e.g. 147.25)
1.13x147.25= 166.3925 or 166.39
Total price including tax= $166.39

Question 7:
A herd of caribou moved to a new location. The population increased by 10% for the first year and then was increased by 20% in the second year.

a) Find the population after the second year.
b) Explain why there was not a 30% increase of the over the two years.



a)  

 100+10= 110     110 ÷100=1.1       1.1x100= 110

100+20=120      120÷100=1.2       1.2x110= 132
After the second year there was 132 caribous.    


b) There was not a 30% increase of the two years because the 100% changed when the second year increased it by 20%. In the first year the population of the caribou was 100, now that the second year came by instead of the population being 100 anymore it increased which is 110% (the new 100%).


Show you know

What is the final sale price at each store? Which is a better buy?
Explain your thinking.
Store A: 50% off one day only.
Store B: 25% of one day followed by 25% off th e reduced price the second day.

Store A: 50% off a $300.00 sofa.
Since the discount is 50% (what you save)off the $300.00 sofa you can divide it by 2 since 50% is half of the regular price.
300÷2= 150 or        50÷100=0.5 0.5x300=150
The total price is $150.00













Store B
First day: 25% off a $300.00 sofa.
So now you are trying to find out what 25% of $300.00 is (what you are saving)
25÷100= 0.25     0.25x300= 75
25% off 300.00 is $75.00(what you are saving)

300-75=$225.00 (what you are paying) or
75÷100=0.75    0.75x300= $225.00 (the new 100%)














Second day
 25% off a $225.00 sofa.
Now you have to find what you are saving 25% off of $225.00

25÷100= 0.25    0.25x225.00= $56.25
You are saving $56.25
Now you have to find what you actually have to to pay. Since the discount is 25% off the sale price will be 75% of the regular price(it's 75% because 25+75= 100%) which is $225.00.
75÷100= 0.75   0.75x225.00=168.75
You are now paying $168.75 for the sofa.

















Conclusion
For the conclusion, store a has a better price than store b because in store a you only pay $150.00 and you are saving $150.00 also. In store b you are paying $168.75 off of the new price and you are only saving $56.25. So if you buy from store a you are saving $18.75 of store b.yay. Overall Store A is a better buy than Store B.
