Essential Understandings
Concrete:
- Use concrete cause and effect examples (e.g., add blue (x) to yellow [f(x)] to get green (y).
- Use distance (y)/time (x) scenarios where movement f(x) is the function of time (e.g., how long does it take to cross the room).
- Use a function box, e.g.,
- Recognize in an ordered pair that the first number represents the domain (x-value) and the second number represents the range (y-value).
- Understand function notation (e.g., in y = f(x) is another way to write y is f(x) – read f of x).
- Understand x as the input and y as the output (cause and effect).
- Understand that the graph of f is the graph of the equation y = f(x).

Cluster:
Understand the concept of a function and use function notation. (Algebra 1 - Major Cluster) (Algebra 2 - Supporting 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. |
