Write expressions in equivalent forms by factoring to find the zeros of a quadratic function and explain the meaning of the zeros.

Clarifications:

Essential Understandings

Concrete:

  • Identify expressions with exponents.
  • Create a model with objects to show that the exponent of a number says how many times to use the number in a multiplication.
    • º (e.g., substitute a chip for each “a” .
    º  begin mathsize 12px style a to the power of 7 end style = a × a × a × a × a × a × a = aaaaaaa).
Representation:
  • Simplify an expression into expanded form (begin mathsize 12px style x to the power of 4 end style)(begin mathsize 12px style x cubed end style) = (xxxx)(xxx).
  • Simplify expression into the simplest form: (begin mathsize 12px style x to the power of 4 end style)(begin mathsize 12px style x cubed end style) = (xxxx)(xxx) = (xxxxxxx) = begin mathsize 12px style x to the power of 7 end style.
  • Understand the following concepts, symbols, and vocabulary for: expression, exponent, raising to a power.

Date Adopted or Revised: 06/14 Cluster: Write expressions in equivalent forms to solve problems. (Algebra 1 - Supporting Cluster) (Algebra 2 - Major Cluster) : 

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
