I start every math class that I teach with a warm-up. When the kids are working on the warm-up, I have the opportunity to take attendance and check-in with each kid about their homework. I get a sense of how the class is doing and I know what to give more attention to as we check our homework together.
Here is the warm-up for Monday for my Advanced Algebra students. It ties in directly to what we are going to be working on for the day... finding the the roots of parabolas.
Warm-up: Write the following sentences as an equation. (HINT: only one equation and you've seen it before!) X is the sum of the opposite of b plus or minus the square root of the sum b squared minus the product of four, a, and c. All of this is then divided by 2 times a.
You can leave your guess as a comment and I will post the answer in a couple days. (give the name or the equation)

Ahhhh, the quadratic equation! We used to sing this to the tune of Pop Goes the Weasel. Yeah!
Yup, quadratic formula. I remember it well (even though I try to forget) - LOL
