Description
This is a direct instruction lesson including notes built around an I Do → We Do → You Do model.
In this lesson you will represent a relation in four different ways (set notation, table, mapping, graph), define a function, use the definition of a function to write an example of a function and a non-function, and determine whether given relations in different representations are functions.
Objectives
- Define a function.
- Determine if a given relation is a function.
Perfect For
- Algebra 1
- Regents‑aligned instruction
- Clear, structured note‑taking
- Gradual release teaching models
Included in the Bundled Unit:
Unit 4 -- Introduction to Functions
Other Lessons in this unit:
Function Notation and Evaluation
Domain and Range of Finite Relations
Domain and Range of Continuous Relations
Domain and Range with a Calculator
Graphing Functions with a Calculator
Other Materials in this unit:
Goal Setting, Self-Assessment and Reflection (U4: Introduction to Functions)
