Standards and Benchmarks Covered in this Lesson

          I,1,2: Analyze, interpret and translate among representations of patterns including tables, charts, graphs, matrices, and vectors.

          I,2,2: Develop a mathematical concept of function and recognize that functions display characteristic patterns of change (e.g., linear, quadratic, exponential).

Introduction

Anticipatory Set: I will ask a student to help me demonstrate the relationship between rate, time and outcome (distance production). I will have two students assemble a product (pencil with eraser with a clip) given different restrictions. We will discuss their productivity individually and collectively.

1)     Objectives: -After a short demonstrations and progressing through the investigation, the students will be able to write out an equation relating three or more variables that correspond to a given scenario.

     - Students will also be able to solve an equation with n variables given the value of (n-1) variables.

Input:  We will first discuss the Maintenance Master 1b #6 and #7

¨     Discuss solving for zeros/x-intercept/ roots

¨     Discuss geometric shapes and their properties

Investigation

If there is time remaining, students will work through Investigation 3 (Pg 11) in the text, I will guide them to a deeper understanding of the content by giving multiple representations of the content and by asking carefully designed questions.

Conclusion:

v    Checkpoint Pg 13

v    Ask students if they have any questions or comments about the lesson
