Fadeev, Pavel – Physics Teacher, 2015

Movies are mostly viewed for entertainment. Mixing entertainment and physics gets students excited as we look at a famous movie scene from a different point of view. The following is a link to a fragment from the 2010 motion picture "Inception": http://www.youtube.com/watch?v=q3tBBhYJeAw. The following problem, based on images in facing…

DeJarnette, Anna F.; Rosado Lausell, Sahid L.; González, Gloriana – Mathematics Teacher, 2015

How can geometry teachers design great tasks that allow students to make connections among interrelated concepts and expand their geometric reasoning skills? Many curricular materials provide problems for students to apply a single geometric concept. However, these problems do not always promote reasoning opportunities for students, because…

Viro, Julia – Mathematics Teacher, 2014

Constructing viable arguments and reasoning abstractly is an essential part of the Common Core State Standards for Mathematics (CCSSI 2010). This article discusses the scenarios in which a mathematical task is impossible to accomplish, as well as how to approach impossible scenarios in the classroom. The concept of proof is introduced as the…

Gonzalez, Gloriana; DeJarnette, Anna F. – Mathematics Teacher, 2013

What does problem-based instruction do for students and teachers? The open-ended geometry problem presented in this article, along with examples of students' work on the problem, illustrates how problem-based instruction can help students develop their mathematical proficiency. Recent studies have shown that students who experience problem-based…

Wares, Arsalan – International Journal of Mathematical Education in Science and Technology, 2010

The purpose of this article is to provide examples of "non-traditional" theorems that can be explored in a dynamic geometry environment by university and high school students. These theorems were encountered in the dynamic geometry environment. The author believes that teachers can ask their students to construct proofs for these theorems. The…

Touval, Ayana – Mathematics Teacher, 2009

The kinematics teaching strategy is a teaching method that stimulates kinesthetic intelligence and thus offers students an unconventional approach for exploring mathematical ideas through movement. This article describes how to use the kinesthetic approach to introduce radian measure. The article includes detailed descriptions of easy-to-use…

Cooper, Brett D.; Barger, Rita – Mathematics Teacher, 2009

The many connections between music and mathematics are well known. The length of a plucked string determines its tone, the time signature of a piece of music is a ratio, and note durations are measured in fractions. One connection commonly overlooked is that between music and geometry--specifically, geometric transformations, including…

Bannon, Thomas J. – Mathematics Teacher, 2009

In this article, the classic problem of finding three ways to determine the probability that the pieces of a stick randomly broken in two places will form a triangle is analyzed anew. To be useful in the classroom, an application must be incorporated into an often-crowded curriculum. What is nice about this triangle problem is that it fits in…

Hyde, Hartley – Australian Mathematics Teacher, 2008

In a previous article in this journal, simple constructions were considered to study the reflective property of a parabola and of a paraboloid. The purpose was to help middle school students understand the importance of the parabola shape and its ability to focus parallel rays. The examples demonstrated a use of the two "Cabri" products to study a…

Leadbetter, Mark – Mathematics Teaching Incorporating Micromath, 2007

In this article, the author describes a 200-year-old ladder problem that can carry learners to high levels of mathematical thinking and activity. This problem requires learners to go from a word problem to an equation to a graph and from there to a solution. As this problem of specifics is turned into a problem using variables, technology,…

Rosenblatt, Louis – Science Teacher, 2004

Inquiry labs in the science classroom help students make connections and discover scientific relationships for themselves. This article describes an inquiry laboratory in which students explore the properties of a pendulum. Since most students are familiar with pendulums before they get to high school, they have discovered that the period is…
