# Iowa Core Math Number and Quantity Framework

## Standards

Standard | Description | |
---|---|---|

N-RN.A.1 | Explain how the definition of the meaning of rational exponents follows from extending the properties of integer exponents to those values, allowing for a notation for radicals in terms of rational exponents. For example, we define 5^1/3 to be the cube root of 5 because we want (5^1/3)^ 3 = 5^(1/3)^3 to hold, so (5^1/3)^ 3 must equal 5. | Lessons |

N-RN.A.2 | Rewrite expressions involving radicals and rational exponents using the properties of exponents. | Lessons |

N-RN.B.3 | Explain why the sum or product of two rational numbers is rational; that the sum of a rational number and an irrational number is irrational; and that the product of a nonzero rational number and an irrational number is irrational. | Lessons |

N-Q.A.1 | Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays | Lessons |

N-Q.A.2 | Define appropriate quantities for the purpose of descriptive modeling | Lessons |

N-Q.A.3 | Choose a level of accuracy appropriate to limitations on measurement when reporting quantities | Lessons |

IA.3 | Understand, analyze, apply, and evaluate some common voting and analysis methods in addition to majority and plurality, such as runoff, approval, the so-called instant-runoff voting (IRV) method, the Borda method and the Condorcet method | Lessons |

IA.4 | (+) Describe the role of mathematics in information processing, particularly with respect to the Internet. ( | Lessons |

IA.5 | (+) Understand and apply elementary set theory and logic as used in simple Internet searches. | Lessons |

IA.6 | (+) Understand and apply basic number theory, including modular arithmetic, for example, as used in keeping information secure through public-key cryptography. | Lessons |

N-CN.A.1 | Know there is a complex number i such that i 2 = –1, and every complex number has the form a + bi with a and b real | Lessons |

N-CN.A.2 | Use the relation i 2 = –1 and the commutative, associative, and distributive properties to add, subtract, and multiply complex numbers. | Lessons |

N-CN.A.3 | (+) Find the conjugate of a complex number; use conjugates to find moduli and quotients of complex numbers. | Lessons |

N-CN.B.4 | (+) Represent complex numbers on the complex plane in rectangular and polar form (including real and imaginary numbers), and explain why the rectangular and polar forms of a given complex number represent the same number | Lessons |

NCN.B.5 | (+) Represent addition, subtraction, multiplication, and conjugation of complex numbers geometrically on the complex plane; use properties of this representation for computation. For example, (–1 + √3 i)3 = 8 because (–1 + √3 i) has modulus 2 and argument 120° | Lessons |

N-CN.B.6 | (+) Calculate the distance between numbers in the complex plane as the modulus of the difference, and the midpoint of a segment as the average of the numbers at its endpoints | Lessons |

N-CN.C.7 | Solve quadratic equations with real coefficients that have complex solutions | Lessons |

N-CN.C.8 | (+) Extend polynomial identities to the complex numbers. For example, rewrite x2 + 4 as (x + 2i)(x – 2i) | Lessons |

N-CN.C.9 | (+) Know the Fundamental Theorem of Algebra; show that it is true for quadratic polynomials. | Lessons |

N-VM.A.1 | (+) Recognize vector quantities as having both magnitude and direction. Represent vector quantities by directed line segments, and use appropriate symbols for vectors and their magnitudes (e.g., v, |v|, ||v||, v). | Lessons |

N-VM.A.2 | (+) Find the components of a vector by subtracting the coordinates of an initial point from the coordinates of a terminal point | Lessons |

N-VM.A.3 | (+) Solve problems involving velocity and other quantities that can be represented by vectors | Lessons |

N-VM.B.4.A | (+) Add vectors end-to-end, component-wise, and by the parallelogram rule. Understand that the magnitude of a sum of two vectors is typically not the sum of the magnitudes | Lessons |

N-VM.B.4.B | (+) Given two vectors in magnitude and direction form, determine the magnitude and direction of their sum. | Lessons |

N-VM.B.4.C | (+) Understand vector subtraction v – w as v + (–w), where –w is the additive inverse of w, with the same magnitude as w and pointing in the opposite direction. Represent vector subtraction graphically by connecting the tips in the appropriate order, and perform vector subtraction component-wise. | Lessons |

N-VM.B.5.A | (+) Represent scalar multiplication graphically by scaling vectors and possibly reversing their direction; perform scalar multiplication component-wise, e.g., as c(vx, vy) = (cvx, cvy) | Lessons |

N-VM.B.5.B | (+) Compute the magnitude of a scalar multiple cv using ||cv|| = |c|v. Compute the direction of cv knowing that when |c|v ≠ 0, the direction of cv is either along v (for c > 0) or against v (for c < 0) | Lessons |

N-VM.C.6 | (+) Use matrices to represent and manipulate data, e.g., to represent payoffs or incidence relationships in a network. | Lessons |
