Subject:
Mathematics (9 - 12)
Title:
Graphing Families of Quadratic Functions
Description:
Students will use a graphing calculator to investigate families of quadratic functions. This lesson can be used as a follow up after showing student how to graph by quadratics by hand.
Subject:
Mathematics (9 - 12)
Title:
Parent Functions and Their Children
Description:
In this lesson, students will be able to identify parent functions of linear functions, absolute value functions, and quadratic functions. Students will be presented with functions and asked to graph them by first identifying the basic curve and then using transformations. The transformations that will be highlighted in this lesson are translation and reflection. These activities will be done in teams of four students.
Subject:
Mathematics (9 - 12), or Technology Education (9 - 12)
Title:
Family Ties: Parabolas
Description:
This lesson allows students to manipulate the parameters while using the vertex form of the equation of a parabola to see the effects on the graph. The spreadsheet can be altered for other functions.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.
Subject:
Mathematics (9 - 12)
Title:
Exponential Growth and Decay
Description:
This lesson on exponential growth and decay involves a variety of teaching resources. There are a variety of websites used to teach and reinforce how to identify exponential growth or decay and how to solve problems relating to growth and decay. There is a lab provided that will help model these concepts being taught and computer based practice on these concepts. Videos are provided that give a picture image of how exponential growth and decay works. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

Title:
Linear Alignment
Add Bookmark
Description:
In this Illuminations lesson, students explore linear equations and the effects of changing the slope and y-intercept on a line. It gives students exposure to y = mx + b, and can be used as an introduction to the topic. Using graphing calculators, students are challenged to overlap lines onto the sides of polygons. To achieve this goal, students change slopes and y-intercepts of lines, noting observations about behavior as they work. As students change the y-intercept of a line, they see it raise or lower the line. As students change the slope, they see it affect the steepness of the line.

Title:
Exploring Linear Functions: Representational Relationships
Add Bookmark
Description:
Technology allows the linking of multiple representations of mathematical situations and the exploration of the relationships that emerge. This example from Illuminations presents a series of explorations based on two linked representations of linear functions. e-Math Investigations are selected e-examples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The e-examples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the e-examples are natural companions to the i-Math investigations.
