Spelling Bee

So, why am I telling you this?  Well, for the last two years, I've had this idea of having a spelling bee in my math class.  I guess I would need to call it a math bee since it actually won't involve any spelling.  

Here's how it would work.  Display an algebraic expression, equation, or inequality on the board.  Have a few students stand in a row, spelling bee style.  Ask the first student in the row to read what is written on the board.  If they read it correctly, they get to remain standing.  If they read it incorrectly, they must sit down.  

Why?  Well, I've found that my students haven't really ever been taught to read mathematics.  Mathematics is a language of precision.  3(2) + 5 is not the same as 3(2 + 5).  I tell myself every year that this is going to be the year that I am super picky about how we speak math in my classroom.  And, every year, I am super picky about a few things.  But, I even find myself sometimes slipping up and reading a problem aloud in a less than precise manner.  I justify it in my mind by saying, "Well, students know I actually meant 'times the quantity of' instead of just 'times' because there are clearly parentheses in the problem as it is shown on the SMARTBoard." It's really just me being sloppy, though.

Would this work?  Or am I just having crazy thoughts?

This really is just a half-formed idea.  Hoping someone in the #MTBoS can make it better.
