In a box plot as shown below, there are 5 values:

Minimum (lowest), Lower Quartile (25th percentile), Median (50th percentile), Upper Quartile (75th percentile) and Maximum (highest).

Notice that the question above has the word *not* in it.

**When putting the answer choices into the TI-84 we can see that the only match is II.**

**Analyzing a graph can teach students about the zeros or solutions of a function. This function passes through the x-axis 3 times: at x = -2, x = 1 and x =3. We can also use this question to talk about factoring, y-intercepts, end behavior and other cool Math ideas. The process of elimination is very rewarding as compare/contrast is a great way to learn content and metacognition. **

**I am in favor of students knowing the Math part of this for sure but with the TI-84 , they can get the Math and get points. The 2 points on this type of question may make the difference between Pass and Fail and perhaps even high school graduation. ** The problem below comes from the June 2015 Algebra I Regents.

**Option I is a NO GO so answers (1) and (3) are OUT.**

**Option II looking good — it’s a keeper!! **

**Option III is a NO GO **
