### Anne's First Growing Post

1/2 + 1/6 (>) 1/4 + 7/12
i will be using the clock method because its easier to explain.

-1/2 of a clock is 30 mins because you divide 60 by 2.
-1/6 of a clock is 10 mins because you divide 60 by 6.
-so now add the mins up. 30 + 10 mins = 40 mins. which is like saying 40/60

-1/4 of a clock is 15 mins because you divide 60 by 4.
-7/12 of a clock is 35 mins because 6/12 is half.
-then you add 1/12 to 6/12 because you need to add one more to the numerator to get a 7/12
-1/12 of a clock is 5 minutes because 60 divided by 12 is 5.
-now add the half (6/12) with (1/12) that equals 7/12
-now you have 30 + 5 mins. that equals = 35 mins.

4. "The Bike Race Fundraiser"

5. a) jenna and i were partners, and we decided to count by the number. for example, the km markers are every 12, 6, and 3s. so we decided to count from the start, every 12. and mark it until we got to the end. we did that for every station
b) our bike race is wrong because we didnt find the answer of what 1/8 is out of 60. or 1/10, 1/3, etc. (the stations)

- it shows other sites that lead on to other fun games. one game i chose was fraction monkeys because it looked funny. (some games need shockwave or java to be be able to play) on fraction monkeys, it showed where to hang the correct fraction to the correct place on the number line. there are other games, but i decided to choose fraction monkeys. i think this is a very cool and educational site

7. for the bike race, even if jenna and i did it wrong. we saw a pattern. for every 8th of the way, we would just count .. 1, 2, 3, 4, 5, 6, 7, 8 and mark it there. and we kept doing that until we couldnt do it anymore.

8. two different ways of finding 3/4 of 16.
a) i am going to use the divide denominator x numerator method.
- first divide 16 by 4. it equals 4. then times it by 3. the answer it 12.
b) i am going to use the grouping method?
- first i find out how many groups of 4s can fit into 16. so i figure that its 4 groups of 4. then i times it by 3. so 4 x 3 = 12.

1/2 + 1/12 (>) 4/12 + 1/6
a) 1/2 + 1/12
- 1/2 of an hour is 30 minutes because you divide 60 by 2
- 1/12 of an hour is 5 minutes. because you divide 60 by 12.
- now add it up. 30 minutes + 5 minutes equals to 35 minutes
b) 4/ 12 + 1/6
- 4/12 of an hour is 20 minutes because you divide 60 then times it by 4 because the numerator isnt a one.
- 1/6 of an hour is 10 minutes because you divide 60 by 6
- now add it up. 20 minutes + 10 minutes equals to 30 minutes
c) 1/2 + 1/12 is more by 5 minutes

(sry that i have links to pictures instead of the pictures being there, because it wouldnt post up on my computer so i decided to upload it on freewebs and take the url and post that instead)
