Mr. Oldfield challenged my class the Dan Meyer’s 25 Billion app>>>>>> http://threeacts.mrmeyer.com/25billionapps/. I started by  putting the time we started which is 6:27. At 6:27 the downloads was at 24,658,507,655. I kept doing that for 4 minutes:

• 6:28-24,658,541,892;
• 6:29-24,658,576,918
• 6:30-24,658,610,221

I then subtract the number at 6:28 from the number at 6:27 which equals 34,231. Then the number at 6:29 from the number at 6:28 and that equals 35,026. Then finally I subtracted the number at 6:30 from the number at 6:29 and that equals 33,303. After getting these three numbers:

• 34,231
• 35,026
• 33,303

I added the three numbers up together and got 102,560 and then divided by 3 and got 34,188. 34,188 is the downloads per minute. I then multiplied 34,188 with 60 to get how many downloads are in a hour because there is 60 minutes in a hour which is 2,051,280.  Next I multiplied 2,051,280 with 24 to find out how many downloads there are in a day because there is 24 hours in a day and the answer is 49,230,720. I then got the number of downloads from when we began the project which is 24,658,507,655 and kept adding to the number of downloads per day which is 49,230,720. I added the numbers up seven times and that would mean seven days later. On the seventh day there was 25,003,122,695. That means that there is 3,122695 away from 25,000,000,000. I then subtracted a hour from 25,003,122,695. Which is 25,003,122,695-2,051,288=25,001,071,415. After that I subtracted 40 minutes off of 25,001,071,415. 3o minutes would be 820,512 so 25,001,071,415-820,512=25,000,046,765. So that means the contest will probably end on March 2nd around 7:26.

So far in math I think it’s going good. I understand what we are doing in class. I am doing great on my tests.

I’m going to show you how to find the square root of 19. First you find the two perfect squares beside 19. The two perfect squares would be 16 and 25. It would be 16 and 25 because 4*4=16 and 5*5=25. Then you look to see which perfect square root is closer to 19. It would be 16 because it’s two away from 19. Now, that you know that it will either be 4.1, 4.2, 4.3, or 4.4. After, that you add 4.5 to 16 that equals to 20.5. At this point, you make a time line and you put 16 at the beginning and put 20.5 in the middle and at the end put 25. So now it will be in the middle of 16 and 20.5. So think for a second if your looking 19 where do you think you would find it on a time line? Would it either be 4.1, 4.2, 4.3, or 4.4? So put 4.1, 4.2, 4.3, and 4.4 in order in the middle of 16 and 20.5. So which decimal is where be? I think it would 4.3 because I think that’s where 19 would be. Hope I helped you.
