Into To Algebra

 

1.   Students identify and use the arithmetic properties of subsets of integers and rational, irrational, and real numbers, including closure properties for the four basic arithmetic operations where applicable:

1.1 Students use properties of numbers to demonstrate whether assertions are true or false

2.   Students solve equations and inequalities involving absolute values.

3.   Students simplify expressions before solving linear equations and inequalities in one variable, such as 3(2x-5) + 4(x-2) = 12.

4.   Students graph a linear equation and compute the x-and y-intercepts (e.g., graph 2x + 6y = 4).  They are also able to sketch the region defined by linear inequality (e.g., they sketch the region defined by 2x + 6y< 4).

5.   Students verify that a point lies on a line, given an equation of the line.  Students are able to derive linear equations by using the point-slope formula.

6.   Students solve a system of two linear equations in two variables algebraically and are able to interpret the answer graphically.  Students are able to solve a system of two linear inequalities in two variables and to sketch the solution sets.

7.   Students add, subtract, multiply, and divide monomials and polynomials.  Students solve multi-step problems, including word problems, by using these techniques.

8.   Students apply basic factoring techniques to second-and simple third-degree polynomials.  These techniques include finding a common factor for all terms in a polynomial, recognizing the difference of two squares, and recognizing perfect squares of binomials.

9.   Students solve a quadratic equation by factoring or completing the square.

10. Students understand the concepts of a relation and a function, determine whether a given relation defines a function, and give pertinent information about given relations and functions.

11. Students determine the domain of independent variables and the range of dependent variables defined by a graph, a set of ordered pairs, or a symbolic expression.

12. Students determine whether a relation defined by a graph, a set of ordered pairs, or a symbolic expression is a function and justify the conclusion.

13. Students graph quadratic functions and know that their roots are the x-intercepts.

14. Students apply quadratic equations to physical problems, such as the motion of an object under the force of gravity.

15. Students consistently and accurately compute with, apply and convert the different kinds of forms of rational numbers; begin to work with irrational numbers, especially P:

15.1   Use the inverse relationship between raising to a power and root extraction for perfect square integers; and, for integers which are not square, determine without a calculator, the two integers between which its square root lies (NS 2.4) 7th

16. Students discover, describe, and generalize patterns, including linear, exponential, and simple quadratic relationships and represent them with variables and expressions:

16.1   Understand and use coordinate graphs to plot simple figures, determine lengths and areas related to them, and determine their image under translations and reflections (MG 3.2) 7th

16.2   Know and understand the Pythagorean theorem and its converse and use it to find the length of the missing side of a right triangle and the lengths of other line segments and, in some situations, empirically verify the Pythagorean theorem by direct measurement (MG 3.3) 7th
