  • I can design the track of a roller coaster, determine the sloped curve of an exit ramp, trace the free falling path of a skydiver, and understand the mechanics of controllers like autopilot, cruise control, and a living room thermostat.
  • I will apply mathematical processes for basic operations to algebraic expressions and divide algebraic terms out of algebraic expressions.


2016 VDOE Curriculum Framework - AII.1 Understanding

·  Computational skills applicable to numerical fractions also apply to rational expressions involving variables.

·  Radical expressions can be written and simplified using rational exponents.

·  Only radicals with a common radicand and index can be added or subtracted, which may require rewriting a radical with a lower base and different index.

·  A relationship exists among arithmetic complex fractions, algebraic complex fractions, and rational numbers.

·  The complete factorization of polynomials has occurred when each factor is a prime polynomial.

·  Pattern recognition can be used to determine complete factorization of a polynomial.

·  Polynomials may be factored in various ways, including, but not limited to grouping or applying general patterns such as difference of squares, sum and difference of cubes, and perfect square trinomials. 


The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to

  AII.1b1  Simplify radical expressions containing positive rational numbers and variables.

·  AII.1b2  Convert between radical expressions and expressions containing rational exponents.

·  AII.1b3  Add and subtract radical expressions.

·  AII.1b4  Multiply and divide radical expressions. Simplification may include rationalizing denominators.
