Notes & FAQs

In Algebra 2, students analyze and apply operations using multiple representations of functions to compare, interpret data, and make inferences. Functions include (but not limited to) linear, exponential, quadratic, absolute value, inverse, piecewise, cubic, polynomial, trigonometric, logarithms, etc. They use statistics in real world contexts to develop solutions.

Frequently Asked Questions

What would you say the constant theme of this unit would be?

The constant theme should be starting with a certain representation and becoming comfortable with creating other representations (i.e. table, graph, explicit equation, recursive equation, story context and possibly an pictorial representation), which will allow utilizing multiple standards for math practice to improve mastery, comprehension, and retention.

What about quadratics & unfinished learning?

This unit should be addressing some unfinished learning and prior knowledge with quadratics, while introducing polynomials. As the unit progresses, the goal is to continue emphasizing comparisons of different functions types and their various representations to help define and understand polynomials and quadratics, the characteristics and behaviors that are similar and different from previously mastered functions.

Where is the line between Quadratics in Algebra 1 versus Quadratics in Algebra 2?

ALD levels 1-3 of the learning goal are from the Algebra 1 course. This is the perfect time to reengage these concepts (A-REI.B) while working on complex solutions (N-CN.7). For example, comparing the process of factoring from Algebra 1 with factoring a quadratic with complex roots. What is similar? What is different? Why do we have “complex” numbers? Notice the language above, reengage versus reteach. This is not stopping to teach Algebra 1, but connecting to and extending Algebra 1 concepts to Algebra 2. For more on the difference, see the Again? Tab.

Do I need to take the understanding of quadratics to an ALD Level 4?

While this concept has been identified as Level 4 (advanced) understanding for this Algebra 1 Target, it represents a grade level understanding for Algebra 2 (N-CN.7).
