Distinguishing Functions: Even, Odd, Neither

Resource:
Distinguishing Functions: Even, Odd, Neither

Students will look at examples of Even and Odd functions to generate their own definitions and then further refine their definitions and understanding with a matching activity. There will also be opportunity for students to re-visit and refine their understanding of different function families.

End of Unit Assessment (Algebra II, Unit 4)

After this unit, how prepared are your students for the end-of-course Regents examination?  The end of unit assessment is designed to surface how students understand the mathematics in the unit.  It includes spiralled multiple choice and constructed response questions, comparable to those on the end-of-course Regents examination.  A rich task, that allows for multiple entry points and authentic assessment of student learning, may be available for some units and can be included as part of the end of unit assessment.  All elements of the end of unit assessment are aligned to the NYS Mathematics Learning Standards and PARCC Model Frameworks prioritization.
