 82-2 Number Theory

Students will be able to:

  1. Identify prime and composite numbers
  2. Differentiate between a “term” and a “factor” and “multiples”
  3. Decompose a number into its prime factors
  4. Identify a greatest common factor (GCF) and use to factor simple polynomials
  5. Use inequality symbols correctly
  6. Interpret the meaning of scientific notation with whole number powers of 10

 82-3 Expressions

Students will be able to perform the following calculations without a calculator:

  1. Add, subtract, multiply and divide expressions containing numbers and variables
  2. Estimate irrational roots
  3. Simplify perfect root radicals containing numbers and variables  ( e.g., cube root of x3; √(x2y4))

 Students will be able to:

  1. Apply associative, commutative, and distributive properties to algebraic expressions
  2. Simplify algebraic expressions using the Order of Operations
  3. Combine like terms
  4.  Simplify expressions with positive exponents
  5. Add and subtract polynomials
  6. Multiply binomials

 82-4  Percents and Ratios

Students will be able to:

  1. Calculate and estimate percents (finding the percent, finding the part, finding the whole)
  2. Solve proportions (especially intuitively) in contexts involving percents.
  3. Use benchmarks to estimate the magnitude of numbers

 82-4  Equations, Inequalities and Graphs

  1. Solve simple linear equations with one variable, including those with simple fractions
  2. Graph a linear equation given the equation or a table
  3. Identify ordered pairs that solve a linear equation given a graph, a table or an equation
  4. Find the slope of a line given points on the line or a graph
  5. Understand that a linear function can be represented in multiple ways (e.g., graph, table, equation)
  6. Graph the solution to a linear inequality with one variable on a number line

 82-5  General Mathematical Skills
