Rounding Errors

To investigate rounding more deeply, here is a structure for some questions that hopefully prompt the question, why does this happen?

Here are three examples as a pdf and as a Google doc.  It doesn’t happen in the first example, but it does in the second two.

Next, see if students can create their own to investigate why this happens.  I have created a blank sheet (3 on each page).  Again, as a pdf document and as a Google doc.
