I think that the first puzzle was interesting for us because even though we both read the same directions, we not only interpreted them totally differently but we also both got them wrong.  While James looked at the puzzle, ht was under the impression that not only did they have to be concentric squares, but they would also have to have each corner placed on a dot.  I, on the other hand, did not understand that the squares would have to take place within the plane of the dots, and therefor I just drew my squares big enough that I could fit three of them on the page and still cover all of the dots.  Neither of us got the correct answer, but it was interesting to see how we both interpreted it.

The second puzzle called for use to could how many 'E' shapes we could make out of the area given.  James counted his in a circular pattern in a clockwise fashion, going from biggest to smallest and ended up with 35 (he disagrees, but I am convinced he counted two of them twice).  I on the other hand figured there could only be 4 different sizes of 'E's and once I had figured that out, I went from left to right and top to bottom to count how many times I could fit each size in the image.  Neither of us got the correct answer because we did not take into account the fact that they could be backwards.  This is probably because neither of us saw it as a shape but rather a letter.  Since it was a letter and not a shape, in our minds it could only face one direction.
