Presents different real-world mathematics activities on data display and data analysis with pie charts from different time periods. (ASK)

Presents four related problems that provide examples of ways to include justifications of interesting mathematics in courses taught prior to a geometry course. (ASK)

Presents a project developed for students in grades 9-12 that uses real-world statistical data presented in the print media. (ASK)

Reviews a number of interesting sites on the Internet for mathematics education and considers the different ways in which the information available can be used as a teaching resource. Provides practical guidance on how teachers might take information in text, graphic, and file formats and use it either for themselves or with pupils. (Author/ASK)

Describes an activity on fractal geometry in which students built a 19-foot-tall Sierpinski pyramid in the Minneapolis Convention Center in conjunction with the National Council of Teachers of Mathematics' (NCTM) 75th Annual Meeting in April, 1997. Contains 13 references. (ASK)

Presents an activity in which students try to find the least common multiple (LCM) for two numbers using calculators. (ASK)

Determines the theoretical probability that a regular polygon will cross a crack when dropped onto floorboards. By following two special cases, a pattern emerges that enables students to consider the general case. (ASK)

Focuses on subitizing, the ability to recognize small numbers of objects. Discusses when and how it develops and whether it should be taught. Contains 31 references. (ASK)

Presents an activity that focuses on the features of ellipses and the concepts of limit and infinity. (ASK)

Shares some explorations of Fibonacci sequences with a special focus on problem-solving and posing processes. (ASK)

Presents an activity in which the subject is the identity of the team in the greatest jeopardy of becoming the big loser in a basketball tournament. Explores several facts about the big loser, offering them in a hierarchy appropriate for creating various short- and long-term projects for a high school mathematics class. (ASK)

Provides examples of the uses of proportions from the fields of mathematics and science. (ASK)

Features a brief description of fractals and their characteristics, some example activities, and an argument for including fractals in the mathematics curriculum. (ASK)

Describes a game in which students strengthen their number sense by using mental mathematics to find and check factors and multiples of numbers up to 100. (ASK)

Illustrates how open-ended items offer teachers knowledge of students' understanding on which to base instructional decisions. Presents some items teachers might use to assess their students' understanding of decimals. (ASK)
