Tomorrow is the last day of school before spring break, and I'll be giving a mini-test (only 4 problems) in 2 of my classes. For "bell work" this morning I had problems similar to the test problems up on the board, and I reminded students to get a common denominator before adding the two rational expressions in "the first problem".
One student asked, "is the first problem the one on top?"

Don't you teach HS Math, Darren? Isn't adding fractions middle school math, at the latest? Or do I not understand the general pacing/sequence for California math.

Yes, fractions are introduced in the 4th grade. We're working with rational expressions, which are fractions with variables in the numerator and denominator. An example would be 4/(x+3) + 5/(2x-1) .
Ahhhh ....
Thanks,
