    I am going to use the visual of the paper and two stacks of paper and see what student generated responses I receive. I think it will provide some interesting results.

    I just tried this, and only one student out of 17 did this correctly. What was interesting was that he did not think he did it correctly, and was unsure how to explain his answer. I had another student get the correct answer, but she did it by starting off estimating instead of actually doing math. She divided the 142.75 cm by 2, and then rounded that up to 72, then figured out that each pack of paper was 6 cm. While she got the right answer, and could explain her work quite well, she could have just as easily gotten a wrong answer. I encouraged her use of estimation, but also explained why it could have been wrong.
