Angel's First Growing Post

1.Which fraction is bigger? 1/2 + 1/6 + 1/4 + 7/12
To compare them I used the clocks and i added the minutes for 1/2+1/6 and 1/4+1/5.

1/2 = 30 minutes in 60 minutes /because its half
1/6 = 10 minutes in 60 minutes /60 divided by 6 30 minutes + 10 minutes = 40 minutes.

1/4 = 15 minutes in 60 minutes / to get this answer you divide 60 by 4.

7/12 = 35 minutes in 60 minutes / to get this answer you divide 60 by 12

15 minutes + 35 minutes = 50 minutes
1/4 and 7/12 is bigger by ten .





2.Tell us 2 things about your bike race.
Angel's and Tasha's Bike Race



1. We used clocks and division to solve the questions.

2. We used different colors to tell where all the stops are at.


6. Do a google search for fraction games. Find a good site and write a review of the game. Tell everyone what is good about this site.

http://www.funmaths.com/r011.htm
This fraction game was really fun it's an arcade kind of game.

All levels explain how to do fractions for diagrams, equivalent fractions, fractions equivalent to decimals and percentages, equivalent ratios and simplified ratios.

7. Go back to your picture of the bike race. Tell us all about how you calculated the Km positions at a twelfth, sixth and a third. did you see any patterns?

For 12th we divided it by sixty which equals five for sixth we divided it by sixty and it equals 20. the pattern that i noticed was that some of them landed on the same spot.

8. What are 2 different ways to find a quarter and 3/4 of a number. Use one of the following 16, 22, or 110.

16, You have to divide 1/4 by four because 1/4 is 1 piece of four equal parts, 16/4=4 you will get this answer if you multiply 4x4 because it will give you the answer 16. Multiply 1/4 by 3 to find out what 3/4 of a number is. So 4x3=12 and 12 is 3/4 because 1/4 is 4 and 4x4=16.

SORRY! I don't know what to do for number nine because I haven't done the test! I'll post when I do it.

10) Mark your own Growing post and one other persons growing post. Use the following guide. Paste it in as a comment. Be honest. You may mark a persons work from another room. You may not mark a person's post that has already had a person mark it. Look before you comment.

Vina's First Growing Post

3. In the body of your post please answer the following question. You need to use words and a picture. Which set of fractions is larger 1/2 + 1/6 or 1/4 + 7/12. I would recommend that you use the idea of clocks to show your understanding.
I first half a clock which equal to 30 minutes then i divided the 60 minutes to 6 and it equal to 10 minutes ( 1/2 - 1/6 ). Then I divided 60 minutes to 4 which equals to 15 minutes. Then I divided 60 to 12 which equals to 5 minutes, time 5 minutes to 7 equals 35 minutes( 1/4 - 7/12 ). I added (1/4) 15 minutes to 35 minutes ( 7/12 ) = 50/60, 60 is the denominator because that how many minutes there are in an hour and 50 as the numerator because that the total of the fractions that got added. Then i also did the same thing to (1/2 ) 30 minutes and 10 minutes ( 1/6 ) = 40/ 60.















4.
Find your picture of your final project "The Bike Race Fundraiser" at flickr













5.Once you are at flickr and find your picture save it to your desktop or where ever you save your pictures. You should label it ***bikerace. Then upload it to the blog. Once it is there you will have to select it (double click) then cut it and put it into the right spot at in your post. Tell us 2 things about your bike race.
divide resting points, food wagons, water stations, juice and snack and kilometer marker to 60 and get answer. They all end up at the finish point.
6. Do a google search for fraction games. Find a good site and write a review of the game. Tell everyone what is good about this site. You also need to create a link to the site.
http://www.jamit.com.au/htmlFolder/app1001.html i picked this game because i think its cute and because you have to color a box with the given fraction.
7. Go back to your picture of the bike race. Tell us all about how you calculated the Km positions at a twelfth, sixth and a third. did you see any patterns?
i divided 60 to 12 = 5, 60 to 6 = 10 60 to 3 = 20 or i figure that 12 is half of 6 and 6 is half of 3. The pattern that i saw some of the km markers landed on the same numbers .
8. What are 2 different ways to find a quarter and 3/4 of a number. Use one of the following 16, 22, or 110.
(16)16 multiply to 0. 75 = 12
16 multiply to 0.25 = 4
9) Write a fraction question and answer it. It has to be a question like one you have had on a test. You may answer it in pictorial or word form.

Nigels first growing post

1/2 + 1/6 = 4/6 1/4 + 7/12 = 10/12
double this answer to 8/12

so the 1/4 + 7/12 is bigger

1/2 is 30 min and 1/6 is 5 min so it is 35 min. And 1/4 is 15 min 7/12 is 35 min so its 50 min 1/4 + 7/12 is bigger.

















All the stash ions added up at 60.
There were water, food, juice.

60 / 12 = 5
60/ 6=10
60/ 3=20











http://www.321know.com/fra16_x2.htm#section2

Thats a good fraction game.


22/4=5.5 then 5.5 x 3=16.5


what is lager 1/3 or 1/2
1/2 is larger because the denominator is smaller and the numerator is the same.

I would mark mine a 6/10 because its not on time but i tried my best.

Tasha's First Growing Post

In the body of your post please answer the following question. You need to use words and a picture. Which set of fractions is larger 1/2 + 1/6 or 1/4 + 7/12. I would recommend that you use the idea of clocks to show your understanding.



I think 1/2 and 1/6 is bigger


Tasha And Angels Bike Race

Tell us 2 things about your bike race.

1. Our bike race is very colourful.

2. We tried to answer some of the questions with an idea of a clock and with division.


6. Do a google search for fraction games. Find a good site and write a review of the game. Tell everyone what is good about this site.

My Awesome Fraction Game

The fraction site I found is about soccer. You have to add, subtract, mutiply, and divide and much more to fractions. If you get the answer right, you get to score on the other team. If you get it wrong the oppistie teams shoots on you.



The thing i like about this site, is that it teaches you how to solve the question and taches what you did wrong. I also like that you get to pick what stage you're at like easy, medium, or hard.

Heres the link: http://www.funbrain.com/fractop/index.html

7. Go back to your picture of the bike race. Tell us all about how you calculated the Km positions at a twelfth, sixth and a third. did you see any patterns?




For 12th we didvied it by 60 which = 5 ,6th I divided it by 60 and it= 10. 3rd i divided it by 60 and it = 20. The patterns i noticed were that some of the numbers landed on the same markers , like : 20, 30, 40, ect...





8. What are 2 different ways to find a quarter and 3/4 of a number. Use one of the following 16, 22, or 110.

I can get 3/4 of a number by doing that chop chop thing we learned in class, for example cutting 16 in half (8) then cut 8 in half (4) add both numbers , 4 and 8, and you get 12. So 12 is 3/4 of 16


9) Write a fraction question and answer it. It has to be a question like one you have had on a test. You may answer it in pictorial or word form.
My fraction questions is: Show 2 ways to get 3/4 of 300. In word form, i would do a chop chop thing : cut 300 in half = 150, then cut 150 in half = 75. Add 150 and 75 = 225.
In pictorial form:

(Clocks are used to answer)

1/2=30

1/6=10

30+10=40min












1/4=15min

7/12=35min

35+15=50mins
