Answer(or question to Mentor): Hey Abigail!
The answer to the problem is six miles and 2/5 of a of a mile. I got the six by dividing the five seconds it took for a mile and divided it into the thirty two times. The thirty two is how many seconds on the problem. That gave me six with a remainder of two. Then I just thought it as two counts out of five so I put it over five.

This is great work. You seem to really understand the ratios and division on this problem. I like how you clearly explained to me how you got the 6 and the 2/5. Why don't you try coming up with a different way to solve this now.
HINT: maybe a picture or diagram.
keep up the good work,

Nice beginning. Please be direct and say that the answer is correct. Also, since Jilli didn't actually mention any ratios in her answer, I wouldn't use that word. WE don't really know if she was thinking about ratios, and we don't want to assume something that is not true. Also, if you say her work is "great", then it is inconsistent to ask her to revise or come up with a different way to explain it. So, if you think the answer is suffficient, then encourage her to do the challenge problem. If you think she could explain it more conceptually, then maybe say something like "Suppose that you wanted to explain your thinking to a friend in your class who was confused. Can you find a way to explain why division makes sense?

This is good work. You seem to really understand this problem in terms of division because you got the correct answer. I like how you clearly explained to me how you got the 6 and the 2/5. Suppose you wanted to explain your thinking to a friend in class who was confused , could you find a way to explain why division makes sense?
Keep up the good work,

Answer(or question to Mentor): The answer to the challenge problem for how much sound travels per second was 1,056 per second. I got that answer by multiplying how many feet in a mile. (5,280) Then I got the five, and multiplied those two numbers. (The five was that it takes five seconds each mile.) I came out with the answer of 1,056.

Answer(or question to Mentor): hey abigail! its jillian. i think i have the answers for a few challenge problems. not all.for the one about it travels 6,ooo per minute. it goes 36,000. per day i think it is 8,640,000. The last one i got was per week i am not so sure on htis one but ithink it is 60,480,000. th first on(6,ooo) i got it by adding the number of seconds that lughtning hits the surface and multiplyed it by the number on seconds in a minute. thats how i got that one. The one per hour i got it by getting the 6,oo minutes and multiplying it by 60.the 60 is the 40 minutes in a hour.I got the one about the day bye getting the 360000(hours) and multiplyed it by 24( hours in a day). That gave me the answer. the last one i got about the week ine is i got the day answer( 8640000) and multiplyed it by 7.( the 7 because there are 7 days in one week. bye jillian
