is you is, or is you ain't my baby?

Today in school we were taking a test in reading. It was our third major test of the week, and the kids were feeling pretty fried, as was I. Page after page, we assessed our ability to comprehend, sound it out, spell it right, listen close...

on one page, the kids had to pick the right word to fill in the blank, and it is really assessing kids' ability to choose what "sounds right." for example:

1. Yesterday I ________ my grandmother.
a. visit
b. visiting
c. visited

2. ______ is my mom.
a. she
b. we
c. they


In the middle of the test, one kid raises his hand and asks:

"Mr. D., is we on number 2, or number 3?" All I could do was laugh to myself and ponder the complete lack of authenticity and validity in the tests I was forcing my students to endure.
