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 about unfinished learning?

This unit offers the chance to reengage concepts from middle school and Algebra 1, specifically exponents, expressions, equations & exponential functions as well as the connecting standards from this course & Algebra 1. Unfinished learning can be embedded or compared to current learning to keep students moving forward while filling gaps in understanding.

It's about representations, representations, representations!

The constant theme should be on 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.

Why so many standards?

For now, teacher feedback led to the standards we have here. Further work may need to be done; however, much of what is here can be accomplished together as students create equations, rewrite them, solve them & explain solution steps, graph them & examine key features, and compare them to other functions and different like functions. Frayer models can support these multiple representations.
