Standards

HSN-CN.A.1

Know there is a complex number i such that i2 = -1, and every complex number has the form a + bi with a and b real.

HSN-CN.A.2

Use the relation i2 = -1 and the commutative, associative, and distributive properties to add, subtract, and multiply complex numbers.

HSN-CN.C.7

Solve quadratic equations with real coefficients that have complex solutions.

HSN-CN.C.8

(+) Extend polynomial identities to the complex numbers. For example, rewrite x2 + 4 as (x + 2i)(x â 2i).

HSN-CN.C.9

(+) Know the Fundamental Theorem of Algebra; show that it is true for quadratic polynomials.

Test Protocol

Although my students are encouraged to use use their iPads for homework assignments, in class activities and many other applications, I do not allow them to be used during tests. This is an element of my classroom management that I have wrestled with over the past two years. Although I want to make sure that my students are prepared with 21st Century tools, and I do not want to hide these things from them, I also want to ensure that they can function in an environment with the absence of technology. I am very open with them in my explanation about this. I avoid telling the class that I do not let them use the technology for fear that they will cheat (although that might be a very small part of it)... Hitting the kids with this argument does nothing more that show a lack of trust in them; which can kill a classroom culture built on trust, respect, and responsibility. Instead, I refer the students to SAT, ACT, PARCC and other standardized tests where the use of iPads and smart phones are strictly prohibited.
