# Mathstar Research Lesson Plan

**Comments:** (Describe Social/Cultural content of
school)

Texico is a small school whose primary source of income is the surrounding
dairies.

Texico has a high percentage of cultural diversity. There are approximately 153
students

9^{th}-12^{th} grade.

**I. Description of Unit: **(1 to 2 sentences)

Students are currently studying linear equations, relations and functions. In
this

lesson, students will use a created function machine to comprehend the concepts
of

relations and functions, domain and range.

**A. How does this lesson fit into the unit?
**

**• Previously learned concepts,**(What concepts are needed to do this

lesson?)

Ordered Pairs

Slope and Y-Intercept

Graphing Linear Equations

Solving Linear Equations

**• Concepts to be learned in this lesson**

Relations

Domain and Range

Equations as Functions

**• Concepts to be used in future lessons**

Graphing Parabolas

Exponential Growth and Decay

Vertical Line Test

T-charts

Mappings

**B. Instructional sequence for unit**(Where does this unit fit in the curriculum

for the year?)

Students will have a greater understanding of a function, which is described as a

mapping from each member of the input set, which is called the domain, to

exactly one member of the output set, which is called the range.

New Mexico State Standards and Benchmarks

- Relate mathematical procedures in one representation to
procedures in

equivalent representations.

- Justify the reasonableness of solutions and predictions.

- Use tables and graphs as tools to interpret expressions, and equations.

**II. Plan of the Research Lesson**

**A. Goals of the research lesson: **(What do you want your students to learn

in this research lesson?)

Students will be able to determine whether an equation represents a

function and will be able to find functional values for a given function.

**B. How does the lesson fit into the overaching lesson study goal?
**(Example of overaching lesson study goal: Students will be confident in

their ability to learn.)

Through kinesthetic activities, students will be confident in their ability to

apply previously learned math concepts to that of functions.
