Presents problems designed to focus student attention on the visual representations that accompany the verbal statements of problem situations involving motion over a period of time. Shows that as a result of engaging in these activities, students gain a better understanding of a given problem situation before they apply procedures to answer…

Presents responses to the Marbles problem, which explores the many ways to arrange a given number of square tiles. (Author/YDS)

Describes mathematics activities based on food as a theme. (Author/YDS)

Discusses a meaningful experience, conceptually, of multiplication of fractions. (Author/YDS)

Presents an activity, "Lisa's Lemonade Stand," that actively engages students in algebraic thinking as they analyze change by investigating relationships between variables and gain experience describing and representing these relationships graphically. (YDS)

Presents a measurement problem that can be explored by students of varying ability. Discusses aspects that make it accessible in a heterogeneous class. (YDS)

Discusses problem solutions for questions originally posed in the column "Food for Thought from Jay's Diner." (YDS)

Examines student solution strategies to a problem that appeared previously in this journal. (YDS)

Focuses on the importance of building from mistakes in mathematics instruction to develop better reasoning and problem-solving abilities. (Contains 11 references.) (YDS)

Presents the Shopping Spree problem to teach students the concept of estimation. (Author/NB)

Focuses on children making sense of multiplication. In an activity called "Silent Multiplication," students use what they know about easier multiplication problems to solve increasingly difficult, related problems mentally. (Author/NB)

Develops computational fluency using a game format. Activities involve a standard deck of playing cards. (Author/NB)

Presents responses to the Average Days of Spring problem that appeared in the March 2002 issue of this journal. (Author/NB)

Describes a series of lessons in which 6th grade students explore notions of rates of change and their effect on the shapes of graphs. Addresses aspects of the algebra content standard for the middle grades. (YDS)

Discusses the integration of decision-making exercises into biology courses. (MKR)
