  1. Contest Corner: Math Clubs in Kindergarten? It is happening in 24 New York City Schools!

    Kuchey, Debora; Flick, Michael

  2. Exploring Misconceptions with Rich Tasks

    Glover, Anna
    In the following paper, the author investigates Points on Line Segment, a rich task available on the Stella's Stunners section of the Ohio Resource Center website. The task was posed to 11 high school students in the greater Columbus area. The author advocates increased use of rich tasks in the secondary school curriculum, discussing ratio and fraction misconceptions that upper level students encountered as they solved the problem.

  3. Mathematical Patterning Activities in the Early Grades

    Wang, Qiao
    This article discusses the importance of patterning in early mathematics study for young children and describes some patterning activities for prekindergarten classes to motivate young children to explore the mathematics through observing and creating their own patterns.

  4. Box Full of Mathematics

    Wares, Arsalan
    The purpose of this paper is to describe the mathematics that emanates from the construction of an origami box. The design of this box was inspired by the design of a traditional origami masu box. We first construct a simple origami box from a rectangular sheet and then discuss some of the mathematical questions that arise in the context of geometry and algebra. The activity can be used as a context for illustrating how algebra and geometry, like other branches of mathematics, are interrelated.

  5. Magnifying Mathematics with Digital Microscopes

    Walker, Janet; Campelo, Marina Muniz
    This article describes a series of activities for intermediate-level students to explore ratio reasoning using a digital microscope. In the Common Core State Standards, this subject is addressed for sixth- and seventh-grade students, although this type of reasoning should be introduced at a younger age.Thus, the authors designed this set of activities and then implemented them with a group of fourth-graders.The lesson was well-received and established a foundation for future development of ratio reasoning.

  6. Fractions as Numbers and Extensions of the Number System: Developing Activities Based on Research

    Park, Jungeun; Flores, Alfinio; Hohensee, Charles
    Existing studies have shown fractions present significant challenges for K-8 students and pre-service teachers. They suggest that students may fail to see fractions as numbers and have difficulty moving beyond the part-whole realization, and thus they often think of fractions as objects disconnected from the number system. To address this issue, the current study proposes several activities that can be used in mathematics courses for pre-service elementary/secondary teachers or students to help the mrecognize fractions as numbers with the same visual representations as whole numbers (e.g., the number line) and on which the same kinds of operations can be used....

  7. Revisiting Equal Sums

    Lanstrum, Michael W.
    This article revisits the Equal Sums problem and considers all possible solutions. Depending on the row/column total, various solutions are possible. Sometimes the value of E is unique, sometimes E is not, and in other cases a value of E is not possible. Looking at all possible row/column totals, surprisingly there is only one value that E cannot represent.

  8. Integrating Alternative Algorithms: Possibilities and Practices

    Jong, Cindy; Dowty, Haley; Hume, Bailey; Miller, Maranda
    This article discusses reasons for learning alternative algorithms and the benefits of exposing preservice teachers to alternative algorithms. It presents two alternative multi-digit subtraction algorithm examples, includes perspectives from preservice teachers, and provides strategies for teachers and teacher educators to integrate alternative algorithms in classrooms.

  9. Exploration of Polynomials Through the Use of Code Word Solutions

    Drum, John R.
    The study of polynomials is an important foundational idea in elementary algebra and introductory calculus. This activity will reinforce and introduce ideas about where roots occur, change in slopes over the curve, and determining extremum. This project has students choose a word which has meaning to them, encipher it, and produce a polynomial of their own. From this personalized polynomial they will carry out these studies.
