The goal of this activity is to solve problems encountered when preparing food for space flight. Includes student worksheets. (MKR)

Discusses strategies for overcoming common student misconceptions. Strategies include using pretests followed by teaching techniques planned to contrast new information with students' previous ideas; using pretests followed by time for students to question ideas and test their knowledge; and giving students a real-world task that can only be…

Presents examples of how students can create drawings of sets of lines whose envelopes are parabolas, cardioids, epicycloids, or hypocycloids. Provides students with experience in problem solving, reasoning, communication, and connections between numbers and geometry, between mathematics and art, and between mathematics and other applications.…

Presents activities related to some obscure tests for divisibility, which teachers may wish to develop as illustrative examples in the classroom, or as extension activities for groups of students. Begins with an exploration of divisibility by three, then discusses application of the technique to other numbers, and for numbers written in other…

Presents the stair skipping problem to foster improved communication among mathematics teachers. (KHR)

Presents activities that explore step-cut dissections of whole rectangles. Provides students with the opportunity to discover patterns, which allows them to solve more and more complex problems that offer a context within which students can think about and use different mathematical concepts. (JRH)

Identifies the more representative problem-solving models in environmental education. Suggests the addition of a strategy for defining a problem situation using Soft Systems Methodology to environmental education activities explicitly designed for the development of critical thinking. Contains 45 references. (JRH)

Explains how the moon provides information about the evolution of the solar system and offers scope for physics-based investigations. Uses statistical analysis of real scientific data with which students can predict the diameter and depth of impact craters then compare them with data gathered in institutions or laboratories. (Author/YDS)

Presents activities to incorporate Polya's four-step problem-solving process. (KHR)

Presents a poem written to reassure parents that they make an impact on their children's mathematical awareness through everyday activities. (Author)

Describes an activity in which students roll balls down a ramp to measure the distance rolled under varying conditions. (Author/YDS)

Discusses the Tiles and Sides problem from the December 2000 issue. Indicates that this problem is accessible to students at different grade levels. Presents samples of student responses and their teachers' analysis. (KHR)

Presents a logical reasoning problem pivotal to the novel "Harry Potter and the Sorcerer's Stone" and discusses it at two levels. (Author/NB)

Describes an instructional sequence that promotes student understanding of a coordinate system while simultaneously facilitating understanding of linear relationships. (Author/NB)

Investigates and explores questions and activities related to using a calendar. Students explore number sense and operations, logical reasoning, data analysis, probability, and algebra. (Author/NB)
