Fisheries scientists make sure that fish populations ("fisheries") are managed properly, neither over- or under-utilized, to maintain long-term economic and ecological stability. Scientists collect data and conduct surveys to determine fish populations, and then make recommendations about how many fish may be caught by commercial and…

"Mathematical Thinking: From Assessment Items to Challenging Tasks" is a compilation of 36 problem-based lessons that encourage students to engage in productive struggle and deep thinking. Its 36 full-length lessons for grades 2-8 are each inspired by an actual test item from the National Assessment of Educational Progress (NAEP).…

Motivating middle school students to learn can be challenging. One proven method for doing so is through an integrated curriculum. Educational philosophers and curriculum theorists have long noted the benefits of an integrated curriculum, which recognizes that the subject areas within the curriculum are connected to one another and to the real…

Discusses students' exploration of a particular rational function in the context of people waiting in line for service. The concepts of domain, range, and asymptotes are also developed in that context as is the effect of changes in input variables on function outputs. (Author/NB)

Presents questions, explorations, and problems centered on data and surveys related to ice cream. (YDS)

Investigates how mathematics is used in various careers. Students explore number sense and operations, logical reasoning, data analysis, and algebra. (Author/NB)

Presents an investigation to engage students in real-life, open-ended data analysis. Allows students to analyze existing data along with data that they collect. Lists steps, necessary materials, and includes activity sheets. (Author/NB)

Presents activities to supplement the usual diagnostic procedures that middle school math teachers employ at the beginning of the school year to ascertain the math skill levels of their new students. Includes activities related to problem solving, data analysis, estimation, and fractions. (ASK)

Analyzes a classroom videotape of the Third International Mathematics and Science Study (TIMSS) with a view toward current and future teaching practices. (Author)

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)

Explores how an elimination game played for fun turned into an extended exploration of mathematical problem solving and reasoning. (Author/NB)

Investigates and explores questions and activities on pets. Students explore number sense and operations, logical reasoning, data analysis, and algebra. (Author/NB)

Describes the nature and procedure of individualized inquiry and provides an illustration of its use in one social studies classroom. Steps include problem definition, hypothesis formation, information gathering, data analysis, hypothesis testing, and drawing conclusions. Recommends that teachers select responsible, intellectually capable, and…

Presents activity pages containing world population data for students to use to predict future population figures and Consumer Price Index (CPI) data to track changes in the costs of the goods. Includes answer key. (KHR)

Investigates problems called "cranium crackers" and focuses on number sense, logical reasoning, data analysis, geometry, measurement, and algebraic thinking. (Author/NB)
