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"
- Factor a quadratic equation using a template.
- Use algebra tiles to factor a quadratic equation.
- Use a quadratic calculator to solve the expression. Click Here
º = a × a × a × a × a × a × a = aaaaaaa
- Simplify expression into expanded form ()() = (xxxx)(xxx).
- Simplify expression into the simplest form ()() = (xxxx)(xxx) = (xxxxxxx) = .
- Understand the concepts, symbols, and vocabulary for: expression, exponent, raising to a power and quadratic.
- Understand that a quadratic function is a function where the biggest exponent is 2.
- Factor the expression using the greatest common factor. For example, can be factored into 2x(x + 2)=0.
- Factor the expression in the form of . For example, can be factored into (x + 3)(x+2)=0, the zeros are -2 and -3 which means that the graph of the function crosses the x-axis at -2 and -3.

Cluster:
Interpret the structure of expressions. (Algebra 1 - Major 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. |
