ALEX Lesson Plans
Subject: Mathematics (9  12) Title: Discover the Roots of a Polynomial Function
Description: In this lesson, students will be reintroduced to the Four Step Problem  Solving Plan. The plan will be used as a 'checks and balance' tool for discovering the roots (solutions) of polynomial functions. Students will:
*Explore the problem  identify what is given and what they are asked to find.
*Develop a plan  look for a pattern, make a model, solve a simpler but related problem.
*Solve the problem  carry out the plan
*Examine the solution  check the results with the conditions in the problem, check the reasonableness of the solution
Subject: Mathematics (9  12), or Technology Education (9  12) Title: Investigating Parabolas in Standard Form
Description: Students explore the coefficients of a quadratic function using a graphing calculator. This is an inquiry lesson to be used as an introduction to translations and dilations of functions.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Subject: Mathematics (9  12), or Technology Education (9  12) Title: Who am I? Find A Polynomial From Its Roots
Description: Students analyze the roots and end behavior of a polynomials and write the equation of a polynomial under given conditions. Students apply theorems concerning the multiplicity of roots, conjugates of irrational or complex imaginary roots to find a polynomial under given conditions. Students will factor polynomials to find the complex roots. Students graph polynomials and determine the local extrema. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Thinkfinity Lesson Plans
Subject: Mathematics Title: Building Connections
Add Bookmark
Description: In this lesson, from Illuminations, students make connections among different classes of polynomial functions by exploring the graphs of these functions. The questions in the activity sheets allow students to make connections between the xintercepts of the graph of a polynomial and the polynomial's factors. This activity is designed for students who already have a strong understanding of linear functions, some knowledge of quadratic functions, and what is meant by a polynomial function.
