The traditional technique for converting repeating decimals to common fractions can be found in nearly every algebra textbook that has been published, as well as in many precalculus texts. However, students generally encounter repeating decimal numerals earlier than high school when they study rational numbers in prealgebra classes. Therefore, how…

A solid understanding of the structure and function of cells can help establish the foundation for learning advanced concepts in the biological sciences. The concept of the cell is introduced in middle school life science courses and is continued at the undergraduate level in college (NRC 2012; Reece et al. 2014). Cells are introduced to students…

As current mathematics standards, such as the Common Core, are being implemented throughout the United States, it has become evident that teachers need support to enact the tenets of those standards. To help in this endeavor, this article was published as a guideline to emphasize to mathematics education stakeholders that "effective teaching…

Middle school students' mathematical understanding benefits from connecting mathematics to other content areas in the curriculum. This month's activity explores the issue of the scarcity of freshwater, a natural resource (activity sheets are included). This activity concentrates on the critical areas mentioned in the Common Core State…

Motivating middle school students to learn can be challenging. One proven method for doing so is through an integrated curriculum. Educational philosophers and curriculum theorists have long noted the benefits of an integrated curriculum, which recognizes that the subject areas within the curriculum are connected to one another and to the real…

Getting and keeping the attention of an eight-grade algebra class can often be a challenge. Doing so while trying to meet curriculum expectations and standards can be a daunting task unless projects are designed to both pique and maintain student curiosity. Projects designed around standards that initiate interest and have multiple entry points…

Given a 5-peg by 5-peg geoboard, how many different lengths can be made by stretching a rubber band to form an oblique segment between any two pegs? This investigation requires students to make connections to the Pythagorean theorem, congruence, and combinations. With its use of visual representation and a range of mathematical ideas that can be…

This article describes an activity that introduces the Lithuanian holiday tradition of decorating with straw ornaments in geometric shapes. By building a Lithuanian sunburst star with straws, students explore a number of geometric relationships and reinforce their mathematical vocabulary. It also provides an excellent foundation for a…

Presents an article featured in the March issue of "Mathematics Teaching" that discusses the necessary components of active learning in mathematics classrooms. Considers constructivist framework for analysis of mathematical learning activities that need to be carried out with consideration of aspects of presentation, the nature of pupils' mental…

Mathematics teachers can tap into students' curiosity about hurricanes to develop their understanding of mathematical ideas within a real-life context. This article discusses hurricane-based mathematics tasks involving cooperative learning that were found to help students enhance their understanding of patterns, graphs, and rates of change. For…

Advocates a constructivist approach to learning mathematics in which children are given ample time to think and reflect about numbers and exchange ideas with peers. Teachers should construct a classroom environment in which children invent methods to solve problems. Every child's thinking must be assessed in order to guide each to a higher level…

Describes a classroom project involving the construction of a holiday mobile. Necessary supplies include a lightweight hanger, construction paper, string, scissors, protractors, compasses, and rulers. Concepts involved in the construction of the project include illustrating a chord, radius, diameter, shapes, metric measuring, circumference, area,…

Describes a teaching approach that uses an operating classroom business to fund service learning projects. (YDS)

Describes four learning characteristics that make learning and doing mathematics difficult for students with special needs. Discusses instructional strategies that make learning and doing mathematics attainable for these students in the context of a vignette based on real-life experiences. (YDS)

This article provides activities that merge two fascinating mathematical topics: the Mayan system of numeration and magic squares. (Contains 3 figures.)
