### Angelic's Percentage Growing Post

STATUS
: complete

Question 1

What is a good definition of percent? You should use words symbols, pictures and numerical examples in your definition. (suggestion gliffy is an excellent tool for adding detail to your definition.)

-----------------on to the next question-----------------

Question 2

How are three fifths (3/5), 3:2, 60% and 0.6 all the same? Use pictures and words to show your answer.

They are all equivalents.

3:2 -> 3 + 2 = 5 -> 3/5 -> 3 (divided by) 5 = 0.6 -> 0.6 x 100 = 60 -> 60%

Question 3

Show 3 different ways to find 35% of 80. (bubbleshare is an excellent tool to animate the many different ways of finding these answer).

This Bubbleshare thingy I made show three of the many ways to do this question. The ways are separated by a slide with the number 80 on it so you won't get confused. Hope it's useful!

Question 4

Find a link to blogs that deal with percentages. Leave a comment behind and add the link with a review (What the post was talking about....yes you have to read the post and why others should read the post) Hint In the side bar there are links to other schools. Three of them have done work on percentages!

I left a comment on this post right here --->

3.5/5

It's a great post because the examples the person uses really helps you to understand percentages. I only had one little suggestion for the person, to have a better picture to use for 2/5. They put 2 pingpong tables, so it only represented the denominator. I made a suggestion for them to put 5 groups of stick people (representing the family) and have 2 of them with a pingpong table. If the person who did that put a picture like i suggested, i would've given them 4/5.

-----------------on to the next question-----------------

Question 5

The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms. Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.

Ms. Stanzi can be CORRECT because they never mentioned how many students there are in each class. Here is a diagram I made on Gliffy showing my work:

Question 6

Use a hundred grid (unit square) to illustrate the following questions once you have explained and illustrated what the question means solve it.

a) 16 is 40% of what number?

This question tells us that 40% of a number is 16, so we have to find what that number is exactly. So first you divide 16 by 4.

16 (divided by) 4 (or 40%) = 4

You divide it by 4 because to find 10% of something you must divide that number by 10. Then you must multiply it by the number of the groups of 10 you want, in this case 4. So basicly, we have to work backwards to find the answer to this question. To work backwards, you have to replace MULTIPLY into DIVIDE, and the same goes for the final step.

You are left with the number FOUR. 4 represents the amount that 10 unit cubes (a rod) stands for. In 100 unit cubes (a flat), there are 10 rods, or 10 GROUPS OF FOUR:

10 groups of 4 = 40

So there for 100% is equal to 40.

b) What is 120% of 30?

**To fully understand this Bubbleshare presentation, please click on it =) It will allow you to see Jumpy and Frosty and their conversations.

This question is asking us to find 120% of 30. If you convert 120% percent into a fraction, it would be 120/100. Obviously that number is an improper fraction (the numerator is larger than the denominator), so you would need to squares to solve the problem. 100% would equal 30 and so, you would need to find 20% and then add it to 30. Well then, let's get started!

First, we need to find 10% of 30.

30 (divided by) 10 (10%) = 3

The next step is to multiply the product by two (2 groups of 10).

2 groups of 3 = 6 -or- 20%

All that's left to do is add 100% (30) to 20% (6). If you add those 2 together you get 120% (100 + 20 = 120)!

100 = 30
+20 = 6
120 = 36

And there you have it =) Oh! I forgot that i made a Bubbleshare thingy on it . . . Here it is =)

Setup: 5/5 because you have all necessay information to get full marks

Question 1: 9/10 because you have pictures to show your ansewer and you used bubble share

Question 2: 9/10 because you showed all pictures to show your answers and how to get them

Question 3: 10/10 because you have all 3 of the questions done and you used bubbleshare

Question 4: 5/5 because you made a really good post for the other persons post. It showed a lot

Question 5: 10/10 because again I love how you used your colours and how you did your pictures in bubbleshare

Question 6: 14/15 because you did a really good job with bubbleshare and you did an amazing job with the whole post.

Overall mark: 62/65

You did a really good job Angi and I loved the variaty of colours in the bubbleshare pics. The thing you could improve on though is to try other tools then just bubbleshare. I know its the easiest but try wikitools or glifft so you have a different variety of tools on your post. You did a really Good Job=)

i did use gliffy . . . and . . . i did use a picture, or rather a bubbleshare, on question 2 so i guess it would count as pictures ?

Setup
5/5
Comments: I labelled and titled my post correctly, and I put the questions in a different colour than the answers. =)
Question 1
9/10
Comments:I answered the question correctly (I used the thingy that we did during class on our first day of dping percents so ya), I have 3 types of examples, and I have a picture for the question that I made with Gliffy.
Question 2
9/10
Comments: I did all the thingys necessary but I guess it doesn't show how long I worked on the queestion XP
Question 3
10/10
Comments: I showed 3 ways to do the problem and I illustrated each of the ways. I tried to make the pictures connect, so i guess that would be showing extra effort.
Question 4
5/5
Comments: I made a suggestion for the person who made the post and I also said what they did good.
Question 5
9/10
Comments: I guess I didn't the most effort I put into this question was trying to put the people on the picture because it was annoying, but I did the rest well.
Question 6
15/15
Comments: This question was probably the one that I worked the hardest on. I spent most of my time on it for some reason , and so , ya XP
Overall Mark
62/65
I guess I could improve on the post by being a little more descriptive on the other problems and not spend all my focus on 1 problem XP
