Math 2 F.IF.9, A.CED.1 Assessment Title: Quadratic Representations Unit 2: Quadratic Functions: Representations
Learning Targets:
I can compare properties of two functions each represented in a different way
Directions
1. You will receive information for a quadratic in one of five forms.
(a) Table
(b) Graph
(c) Vertex Form
(d) Standard Form
(e) Factored Form
2. Your mission is to find the person in the room with the equivalent function.
3. Once your ‘match’ has been found your job is to recognize and produce the three missing formats
from the list above.
4. If you do not have a ‘match’ in the room, you must partner with the others (there will be others)
who did not have a match. Your challenge will be to manipulate one piece of information in one of
the forms to create equivalent functions. Once this has been accomplished continue to produce the
other forms as stated in #3. (This is provided as an extension/optional exercise)
Included items for Activity:
Cards containing all five forms of functions so teachers may pick which two to hand out. (This
will help make checking easier)
2 sets of ‘error’ cards (last two pages). Note: last box provides opportunity for error box to be
handed out.

Observational Checklist for Quadratics Representations
Objectives: 1. I can find a student with a card that matches mine 2. I can represent the quadratic on my card in three unique equivalent forms
Coding: I=Student needs instruction and cannot yet achieve this objective. P=Student needs more practice on this objective, but is beginning to understand. A=Student is ready to apply this objective to various situations.
Objective #1 Objective #2 Objective #3
