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

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.

C. Steps of the research lesson:
(See attached table)

D. Things to prepare/materials:

Shoe boxes – student function machines
Construction paper
