Included in contemporary mathematics curricula is the expectation that mathematics teachers will use technology--computers and calculators--in their classrooms. It is widely believed in Australian educational circles and in society at large that students' learning will be enhanced by engaging with these technologies. For children to use computers…

This article describes a technology-based approach for dealing with a misconception that some students hold concerning the equivalency of geometric transformations. Students can begin to conceptualize transformations in terms of the relationship between preimage and image figures rather than focus on the motion of a figure. (Contains 7 figures.)

This article describes a middle-school project that challenged students to design scale models of three-dimensional blocks used in theater programs. Students applied skills such as measurement, proportionality, and spatial reasoning in a cooperative setting. (Contains 1 table and 9 figures.)

This article discusses the importance of measurement in providing a foundation for mathematical study and how measurement can be integrated with other mathematical strands. (Contains 1 table.)

During the preliminary stages of classroom-based research, this author conducted a sequence of interviews with six seventh graders regarding their understanding of fractions, decimals, ratios, and proportions. The students represented a variety of ability levels and were all in their first semester of prealgebra. The interviews began with notions…

This article describes activities for developing an understanding of a formula for calculating the volume of a rectangular prism. The core activity concerns determining the volume of water in a backyard skating rink. (Contains 4 figures.)

This article describes an investigation involving several designs of airplane wings in trial flight simulations based on a NASA CONNECT program. Students' experiences with data collection and interpretation are highlighted. (Contains 5 figures.)

This article showcases four Shel Silverstein works and how they can be used to launch mathematics investigations across the curriculum. Each selection focused on a different mathematical strand; for example, a poem titled "Where the Sidewalk Ends" demonstrates measurement and proportional reasoning, and another poem, "Falling Up," demonstrates…

This article describes different ways that teachers and students interact in mathematics classrooms and the implications of those interactions for students' opportunities to share their thinking. (Contains 1 figure.)

This article describes an activity in measurement and geometry in which sixth-grade students explore the volume and surface area of a donut. Through calculation, creative thinking, and discovery, the students enhanced their geometric vocabulary and reasoning. (Contains 9 figures.)

This article describes how a mathematics teacher uses literature and creative writing in her ninth-grade classes to motivate, instruct, and assess her students. (Contains 4 figures.)

Theorem acquisition and deductive proof have always been core elements in the study and teaching of Euclidean geometry. The introduction of dynamic geometry environments, DGE (e.g., Cabri-Geometre, Geometer's Sketchpad), into classrooms in the past decade has posed a challenge to this praxis. Students can experiment through different dragging…

This study examined why female adolescents choose to opt out of the math pipeline during high school more often than males, which has implications for their long-term careers. (Contains 3 figures.)

According to Kilpatrick (1987), in the mathematics classrooms problem posing can be applied as a "goal" or as a means of instruction. Using problem posing as a goal of instruction involves asking students to respond to a range of problem-posing prompts. The main goal of this article is a classification of mathematics questions created by Years 8…

This article describes Cryptography, defined as the science of encrypting and deciphering messages written in secret codes, it has played a vital role in securing information since ancient times. There are several cryptographic techniques and many make extensive use of mathematics to secure information. The author discusses an activity built…
