One of the most important roles of a teacher is to create a safe space for learners, consistent with the Center for Applied Special Technology (CAST) Universal Design for Learning guidelines (CAST 2011). Universal Design for Learning (UDL) is a framework for teaching and learning, based on neuroscience research, that guides teachers to eliminate…

In this article, Ceyanes, Lockwood, and Gill use "The Geometer's Sketchpad" in a sequence of algebra lessons to introduce quadratic functions as the product of two linear functions. The lessons provide an enriched look at the creation of parabolas and allow students to experience the foundational idea that all functions are…

According to the National Center for Education Statistics (2016), the number of public school students in the United States who were English learners (ELs) was estimated at 4.5 million. However, in 2005, the national standardized testing scores (Fry 2007) show that about 51 percent of eighth-grade EL students were behind other students in reading…

This article addresses the struggles teachers face when they attempt to change their teaching style in order to achieve an ideal mathematics classroom. With the implementation of the Common Core State Standards, many of the behaviors associated with an ideal mathematics classroom appear within the Standards for Mathematical Practice, on which…

A WebQuest is an inquiry-based lesson plan that uses the Internet. This article explains what a WebQuest is, shows how to create one, and provides an example. When engaged in a WebQuest, students use technology to experience cooperative learning and discovery learning while honing their research, writing, and presentation skills. It has been found…

This article describes the use of microteaching lesson study as an approach to promoting collaboration and learning among teachers, particularly those in prospective-teacher education programs, through a repeated cyclic process of developing, implementing, analyzing, and revising mathematics lessons and reporting their experience. (Contains 3…

Three approaches for teaching students to solve inequalities involving absolute values, quadratic expressions, and rational expressions are illustrated. Then one technique that can be used with all of these problems is presented. (MNS)

The author describes simple techniques for providing individualized help within a group teaching situation. (SD)

Describes a way of using multiple representations to help students learn data analysis and make sense out of a large amount of data. Includes an activity for a group-learning environment. (KHR)

Presented is a script for a classroom presentation introducing weighted means and geometric means to students who are already familiar with arithmetic means. Frequent questioning is included to keep the students mentally active and involved in the development of this new idea. Typical student responses to these questions are provided. (CW)

Teacher's guide and master work sheet are provided to be used to explore geometric properties within a problem-solving activitiy. (MK)

Describes an investigation-based, lecture-free first-year algebra course in which students are responsible for compiling their own textbooks. Discusses the purpose and procedures of the activity. Includes student worksheets. (KHR)

The game of "Guess What" is described as a stimulating vehicle for students to consider the unifying or distinguishing features of geometric figures. Teaching suggestions as well as the gameboard are provided. (MNS)

Offers suggestions to make homework more beneficial to students and teachers. Discusses motivating students, planning assignments, grading, communicating teacher expectations, and maintaining consistency with respect to homework. (MDH)

This article is the first in a series that connects the National Council of Teachers of Mathematics "Curriculum and Evaluation Standards" with the new document, "Professional Standards for Teaching Mathematics." The four focal components of the "Professional Teaching Standards" are given, followed by a deeper…
