Us S.F and K.T did a roomful of dots. We had to figure out how many sheets of paper with 2,000 dots on it would take to fill our whole classroom, and how much it would weigh. First we did an estimate to guess how many dots would fill our classroom, and we guessed more than a billion. Then for the weight of the paper we guessed between 500,000 pounds and a million pounds. Next we had to figure out the real answer, for the dots. Next we measured the length and the with of our classroom, we came up with 10 by 9. Then we had to figure out how many reams will cover the classroom floor, we came up with 1,247.5 reams to cover the floor. Then we measured from floor to ceiling, and we got 55.5 reams. Next we multiplied 55.5 *500 cause, there are 500 sheets in one ream and we got 34,618,000. Then we multiplied it by 2,000 because they're 2,000 dots per sheet, then we got 69,236,000,000. Then we had to find the exact answer for weight. we did 4*69,236 because 1 ream = 4 pounds and we got 276,944. That how we did a roomful of dots.

I guess we could have just filled the room with reams of dotted and then just counted them... That would have been quite a mess!!
ReplyDeleteYou two worked very hard on this, I am very impressed! How do you think this challenge problem is related to the math we have been doing in unit 5? Also, what advice would you have for someone else doing this problem?
At lc. Tell me more about the book
ReplyDeleteAt jt the reason is because the story is bast on it.
