Question 2:

Question 3: Show 3 different ways to find 35% of 80.

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 comented on Click! but they have to accept it first. Their post that I read talked about how they used money to explain percents. They did a really good job on their explanations!

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 could have more children in her class than Ms.Lowery. So
Ms. Stanzi could be correct. She could be correct because she might have more kids than Ms. Lowrey. If Ms. Stanzi had 36 kids in her class and Ms. Lowrey had 20 kids in her class, Ms. Stanzi would have 13 children that have met their reading goal of the month because 36 divided by 2 equals 13 or 50%. Ms. Lowrey would have 10 children that had met their reading goal because 20 divided by 2 is 10. Ms. Stanzi could be correct.

Ms. Stanzi and Ms. Lowery could have the same number of children in their classes. Then Ms. Stanzi could be Wrong. For an example they could both have 40 kids in their classes. Then Ms. Stanzi would have 20 kids in her class who met their goal. Ms. Lowery would have about 21 22 23 kids who met their goal.

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?

Formula:

Take 16(since it is worth 40%) and put it over the percentage(40%) to get a fraction. 16 over 40. Then divide the numerator by the denominator to get a decimal(0.4). Multiply the decimal(0.4) by 100 to get the total. 0.4 x 100 = 40(move the decimal to the left 2 times since there are two 0's in 100). Now to check it. If your not sure how to watch the bubble share I created.

b) What is 120% of 30?
Formula:
Divide 30 by 100 = 0.3( Just move the decimal 2 places to the left since there are 2 0's in 100)
0.3 = 1% (multiply 1%(0.3) by your other % which is 120%)
0.3 x 120 = 36
120% of 30 = 36

I did my self assesment(still waiting on two others to asses my work). I marked Thyrza May's work it was done super well.Click 8-41 on here then see here growing post. I also marked Rainer's work who did an awesome job. Click 8-73 Math Blog (2006). Both of these student did an amazing job. If you need help doing your growing post go and check these two out. (but don't copy).
