  1. Graphing Art Revisited: The Evolution of a Good Idea

    Avila, Cheryl L.
    The Graphing Art Project encourages students to explore functions as they create art. Students write functions with domain and range restrictions that generate interesting pictures. The project is easily tailored for different levels of mathematical learners. Algebra 1 students create art using linear functions; precalculus students include conic sections, exponential, logarithmic, trigonometric functions and the greatest integer functions in their work. Students may write graphing calculator programs to reproduce and animate their art.

  2. Overcoming a Common Storm: Designing Professional Development for Teachers Implementing the Common Core

    Bostic, Jonathan; Matney, Gabriel
    Classroom implementation of the Common Core State Standards for Mathematics (CCSSM) requires significant professional development that develops teachers’ understanding of the mathematics content and practice standards. This professional development must begin with the content and pedagogical needs of the teachers it serves. This study examined elementary and middle school teachers’ perceived mathematics content needs related to the CCSSM mathematics content domains, their perceived pedagogical needs, and the connection between these perceptions and statewide assessment data. K-5 teachers indicated a great need in Operations and Algebraic Thinking and Numbers and Operations on Fractions. Middle school teachers expressed a major need in better understanding modeling, statistics and probability, geometry and...

  3. Beyond the Fold: The Math, History, and Technology behind Origami

    Hook, Natalie; Paul, Kristin
    The ancient art of origami can be used to strengthen mathematical subjects in the classroom. By integrating origami into the curriculum, teachers of mathematics provide their students with new opportunities to solidify their understanding of diverse concepts, such as regular polygons, symmetry, and transformation. Using one of many available and free online origami applets, teachers can introduce this ancient craft to their students from a technology-oriented perspective.

  4. Incorporating iPad Technology into the Classroom: A Geometry Project

    Ingraham, Melissa
    Technology is a vital tool that teachers should utilize to help strengthen student understanding. The latest technological tool, the iPad, has the potential to drastically change the way educators present material, and the way students demonstrate their knowledge of subject matter. This article describes in detail a geometry activity done solely on the iPad and explains how the activity is an effective use of technology in the mathematics classroom.

  5. What is the Whole in Cornhole? Introducing and Capitalizing upon Disequilibrium with Fraction Operations

    Lane, Catherine Pullin; Thomas, Jonathan Norris; Harkness, Shelly Sheats
    In this article, we describe a lesson study process aimed at examining and refining division of fractions experiences with pre-service teachers. Through a deliberate, research-based design process, the authors constructed a lesson focused on explicating the nature and mechanics of the traditional fraction division algorithm; however, implementation revealed unexpected yet powerful mathematical experiences that existed aside from the primary lesson goals. Specifically, pre-service teachers experienced significant disequilibrium regarding the shifting nature of "the whole" when working on a particular subset of lesson tasks. The authors describe their design process, implementation, and present several conclusions gleaned from this experience.

  6. Developing Children’s Proportional Reasoning: Instructional Strategies That Go the Distance

    Larson, Katie
    Proportional reasoning is one of four key areas of instruction for sixth and seventh grade mathematics as established by The Common Core State Standards for School Mathematics (CCSSM, 2010). This article describes the importance of proportional reasoning and provides educators with strategies that can be implemented in the classroom to help students develop their proportional reasoning.

  7. Algebra: The Key to Student Success, Or Just Another Hurdle?

    Wilder, Sandra
    The strong emphasis on algebra has led to nationwide school reforms, and it is an integral part of major high school curricula changes that have taken place in recent years. In this article we try to determine if there is a basis for the underlying belief that algebra equips students with the skills necessary to succeed in college. Based on the existing literature, it follows that college algebra may be an indicator of student success in college, but there is no evidence that this subject contributes to that success. There is no evidence of the context or structure of algebra aiding students in developing or even...

  8. Contest Corner: Are Common Core Standards Addressed by Statewide Mathematics Contest Questions?

    Kuchey, Debbie; Flick, Michael

  9. Mathematical Morsels: Solutions to Tasks From the Fall Issue
