I’ve been working on a problem   seems like all the day!
Now, I fin’lly got a number,   so I’ll put my book away--
But then I hear my teacher calling: “Don’t rise up so soon!
You need to check your work for errors -- no one is immune!

Dinah won’t you check, Dinah won’t you check,
Dinah won’t you check your work?
Dinah won’t you check, Dinah won’t you check,
Dinah won’t you check your work?

(‘cause) somethin’ went wrong for NASA  near Mars in ‘99:
A pricey spacecraft blew up    from units not aligned!

(So) check your units now and the answer’s magnitude
Does good reasoning      back what you conclude?”
