### Math models can predict dropout rates

As the number of classes students fail goes up, so do the chances they’ll drop out, a new mathematical modeling approach has found.

Scientists from Berkeley and Mich. develop a model from a math perspective for how genes are expressed in different cells at different stages.

Creating 2 equations in 2 unknowns to describe a set of conditions is a skill algebra 1 students need if they’ll be taking the PARCC test this spring.

How would you figure out (and explain) when one car, traveling at a given speed, will overtake another car that had a head start?

Adding, multiplying, & subtracting polynomials is tested, quite thoroughly, on the PARCC algebra 1 test, used in Md. and some middle schools in IL.

What did Kellyanne Conway mean when she said the president was planning to “repeal” the Common Core State Standards?

Solving equations for a variable of interest is required in algebra 1 on the PARCC test (and in the Common Core). Students find the radius of a circular pool.

Is a given ordered pair on the graph of a function? Algebra 1 students should be able to figure it out, esp. those who will take the PARCC test this year.

The zeros of a polynomial are the *x* values when the polynomial equals 0. Do you know how to find the zeros?

8th graders learn to use mathematics to reason and analyze systems of linear equations in 2 variables.
