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.

3/5 , 3:2, 60% and 0.6 are all the same because they can all convert into each other.

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!

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 right if her class had more students than Ms. Lowrey had in her class.

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?

16/40=0.4
0.4x100=40
40/100=0.4
0.4x40=16 16 is 40% of 40

b) What is 120% of 30?

30x1=30 30/100=0.3
0.3x20=6
100+20=120
30+6=36
120% of 30 is 36.
