Mondays Scribe Post



On Monday we started the day with one of several proportion quizzes .
The quiz looked like this:

1) Tell what fraction the top line is of the bottem line. Also show the fraction simplified.
10 out of 20= 1/2


10 out of 25 = 3/5

2) Give several names for what is shaded and show how you know it is right.



5/9
next one
20/36=10/18

Mr. H asked us to do a couple of questions about percents . One of the questions was :



What is 40% of 70 ?



70*100=0.7



0.7x40=28



40/100 = 28/70






After we did a 3 more questions , he handed us this blue booklet . The first question was to shade in 50% of the squares given . We also had to show it in different ways .






These were two ways i did it :













After we finished shading in 50% of 6 squares , we did the same thing , but we had to shade in 75% of the squares .


Here's some of the things i did :

Then , after we were done all of that . Mr. H told us to do Question C for homework . The question was to figure out the fractions for the squares shown .

Today in class we went over the first page of the blue book that was given out yesterday. First was how to shade in 1/2 of a square of 16 and 1/3 of a rectangle of 27.

1/2 of 16--8

1/3 of 9--9


example:
A. 1/2=8/16

















It does not matter which way you fill in the shape, just as long as there is a certain amount filled in to represent your fraction.
C(flags)
The flags were a bit more difficult but there is a technique to solving them:
!--Pictures coming soon--!
Just divide the rectangle into sections or try to fit together the filled-in shapes to determine how much of the flag is shaded.
Homework:
blue book--second page:
Tell what fraction the top line is of the bottom line
Numerator over Denominator--Part over whole--first # over second #

Michelle's Percentage Growing Post

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.)



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.

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!

This post talks about percentages. Per means 'part' and cent means 'for every hundred'. Percentages are a lot like ratios because they are both comparing multiple numbers.
A percentage formula would look like this:
Numerator divided by denominator=decimal multiplied by 100=_%
Others should read this post because it can help them if they don't understand percentages.

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 be correct because 50% of any number is always half and 55% of any number is more than half. Ms.Stanzi could be wrong because it doesn't matter what number or how big that number is.

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?

16 is 40% of 40

b) What is 120% of 30?

120% of 30
120 divided by 100=1.2
1.2 multiplied by 30=36
120% of 30=36

I Marked and Commented On:
Julie Rose 8-16 I gave it a 60 out of 65.
Marielle 8-17 I gave it a 60 out of 65.
Nick 8-16 I gave it 19 out of 65.
