Rainer'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 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).



































*****************************************************

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 link is about finding 1%, 5%, 10%........
it makes it easy to find percents like 16% when you know1%, 5% and 10%.
(i cant put a comment for this because the comments are closed)

this blog shows how a certain percent can be equal to a decimal
**************************************************************

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.

This could be right or wrong. It all depends on the number of people in the class.

Pretend that Ms.Stanzi's class has 40 people and Ms.Lowrey's class has 30 people.

Well 50% of 40 (40/2=20) is 20 while 55% of 30 (30/100x55=16.5) is about 17.

So more people in Ms.Stanzi's class met the goal.

Now pretend that Ms.Stanzi's class has 30 people and Ms.Lowrey's class has 40 people.

Well 50% of 30 (30/2=15) is 15 while 55% of 40 (40/100x55=22) is 22.

Now more people in Ms.Lowrey's class met the 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?



b) What is 120% of 30?
