1 Toothpicks and Transformations: Quadratic Functions Resource Type: Lessons Discipline: Mathematics Grades: Grades 9–11 Professional Commentary: How many toothpicks does it take to make an n x n square composed of 1 x 1 squares? The lesson begins with a review of transformations of quadratic functions--vertical and horizontal shifts, and stretches and shrinks.... 2 Look At All Those Leaves Resource Type: Lessons Discipline: Science Grades: Grades PreK–1, 3 Professional Commentary: The purpose of this lesson is to observe, measure, and sort tree leaves. Students will learn to examine leaves individually, in groups, and in relationship to the entire tree.... 3 Functions and Transformations of Functions Resource Type: Content Supports Discipline: Mathematics Grades: Grades 11–Postsecondary Professional Commentary: This tutorial begins with the definition of function and illustrates the graph, domain, and range of several nonlinear functions. These same functions are used to illustrate even (symmetric about the y-axis) and odd (symmetric about the origin) functions.... 4 Paper Quilts 4: Exploring Turns Resource Type: Lessons Discipline: Mathematics Grades: Grade 8 Professional Commentary: In this fourth lesson (of a unit of six) students use a 4-square quilt pattern to explore rotations (turns). The site includes activity and recording sheets, discussion questions, extensions, suggestions for assessment, and reflection questions for the teacher.... 5 Transforming Graphs of Quadratic Functions Resource Type: Assessments Discipline: Mathematics Grades: Grades 9–12 Professional Commentary: Students use the innovative graphical interaction to experiment and create the image of the transformed function, providing a dynamic technological replacement for paper-and-pencil sketching. While the technology is not essential to solving the problem, it provides a support for students to interact with function transformations and has significant implications for future item development—a next iteration of... Resource Type: Assessments Discipline: Mathematics Grades: Grades 9–12 Professional Commentary: This task requires an understanding of the function concept across representations, as well as a number of basic skills in functions. The multipart nature of the task allows for greater depth of comparison between the two functions than a one-point item would.... Resource Type: Lessons Discipline: Science Grades: Grade 5 Professional Commentary: The purpose of this resource is to help students further understand the predator/prey relationship by researching specific examples of birds (predators) and what they eat to survive (prey). Middle school students have been introduced to the concept that animals eat other animals and plants to survive.... 8 Classification 1: Classification Scheme Resource Type: Lessons Discipline: Science Grades: Grades PreK–Kindergarten, 3 Professional Commentary: The purpose of this lesson is to show students that many kinds of living things can be sorted into groups in many ways using various features. Students will decide which things belong to which group and will vary their classification schemes depending on the purpose.... Resource Type: Content Supports -- Activities and rich problems Discipline: Mathematics Grades: Grades 10–12 Professional Commentary: Find the range of a composite function. This problem is one of Stella's Stunners, a collection of challenging and entertaining mathematical problems to intrigue students in grades 6 - 12. The Stella problems are ideal for promoting inquiry, problem solving, and classroom discussion of key mathematical ideas.... 10 American Immigration Past and Present: A Simulation Activity Resource Type: Lessons Discipline: Social Studies Grades: Grades 9–12 Professional Commentary: This is a very comprehensive lesson plan where students evaluate the American immigration heritage and the important issues that surround immigration policy, both past and present. The lesson is divided into three parts: a small group activity that simulates a Commission Hearing, individual explorations on immigration policy, and a final research project dedicated to the investigation... |
