In this program, internationally acclaimed mathematics educator Dr. Monica Neagoy, explores the nature of linear functions through the use TI graphing calculators. Examples ranging from air travel, construction, engineering, and space travel provide real-world examples for discovering algebraic concepts. All examples are solved algebraically and then reinforced through the use of the TI-Nspire. Algebra teachers looking to integrate hand-held technology and visual media into their instruction will benefit greatly from this series. Concepts explored: Standard form, slope-intercept form, point-slope form, solving linear equations Note: The download for this resources is the Promethean Flipchart.

A dodecahedron is a three-dimensional geometric shape with twelve flat faces, each a regular pentagon.

Description

Dodecahedrons are part of the family of Platonic solids, known for their symmetry and aesthetic appeal. They are used in various fields, including molecular chemistry and architecture, where symmetry plays a crucial role. Understanding dodecahedrons is important in math education as it introduces students to complex geometric shapes and their properties. Teachers can use models and diagrams to demonstrate the symmetry and structure of dodecahedrons, fostering an appreciation for geometric beauty and complexity.
