Ways to explore blowing bubbles through observation, experimentation, and discovery are suggested to stimulate gifted children, with attention to such areas as the function of film in the liquid and the reason for the common spherical shape of bubbles. Experiments that children can try and tips for the teacher are presented. (SW)

Presents a unit of study about acorns that involves science process skills and emphasizes interdisciplinary possibilities. (MKR)

Uses pattern blocks to model basic parts-of-a-whole fraction concepts. Suggests that students reflect these models in oral, written, pictorial, and symbolic representations. (MKR)

Provides measurement, estimation, and data analysis activities for grades three to four and five to six using boxes of cereal and containers of frozen yogurt. (MKR)

The more that students see themselves in everyday situations that involve mathematics, the more likely they are to be successful. Incorporating names, ages, and other personal data into mathematical activities is easy and fun. (MKR)

Illustrates exploration of composition of functions, translations, and inverse functions on a graphing calculator. Includes reproducible student worksheets. (MKR)

Presents an activity in which students use geometric figures, rep-tiles, to design a tile floor. Rep-tiles are geometric figures of which copies can fit together to form a larger similar figure. Includes reproducible student worksheet. (MKR)

Presents an activity, involving pentagons and using a figure manipulator such as The Geometer's Sketchpad, that requires students to reason geometrically without making unsubstantiated assumptions based on diagrams. (MKR)

Presents an activity to help students overcome mathematics anxiety by collecting and organizing data through summarization and graphic representation. (MKR)

Presents lessons and reproducible student worksheets for grades three to four and grades five to six to investigate large numbers and comprehend their magnitude. (MKR)

Production of a play by students with deafness can be a meaningful student experience as well as an excellent educational laboratory. An original production at the Model Secondary School for the Deaf at Gallaudet University involved students in set construction, painting, preparing visuals, financial management, using video and other technology,…

Archimedes' method for estimating the value of pi is developed and compared with the Gregory-Machin infinite series method. Programs for the TI-81 calculator for finding the upper and lower bounds using the classical method and estimating pi using infinite series are provided.(Author/MKR)

Examines ways to integrate a discussion of lotteries into a lesson on combinatorics and probability to enhance the teaching and learning of number sense. (Author/MKR)

Presents activities with 10- and 4-straw flexigons, an object created by stringing together lengths of plastic drinking straws with nylon fishing line. Discusses several geometric theorems that can be demonstrated with flexigons. (MKR)
