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!

Here is the link to the post i commented on http://linden8z.blogspot.com/ . It talks about the 3 ways to find a percent and i think others should read it because its VERY helpful

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.

We wouldn't really know because she didn't exactly say how much people are in her class, but then theres a chance she could be right if there were more kids in her class. If Ms. Stanzi was right that would mean there would be 60 people in her class and only 40 in Ms. Lowrey's class. If you divide 60 from 100 then multiply by 50 it would give you 30. For Ms. Lowrey's class, if you divide 20 from 100 then multiply by it 55 it would give you 11. Therefore Ms. Stanzi is right. If it was the other way around then Ms. Stanzi would be wrong.

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?
b) What is 120% of 30?

On the second picture i forgot to colour in the whole hundred chart so that it would be 100% + the 20% = 120% .

You got 60/65 you did good on everything thing. The bubbleshare was nice and i liked how the questions went side to side on the screen, but on question 1 you didn't show a picture and on questoin 5 you didn't explain why or why not Ms. Stanzi's more kids met the reading goal than Ms.Lowrey's class. Good effort though.
