FEATURES

Science Application of Area and Ratio Concepts
Virginia Horak
Using area and ratio concepts to examine why some animals, or people wearing different types of shoes, sink into the surface on which they are standing. Students compute "sinking values" to explain these differences. Includes ready-to-use worksheets.

Lettuce Learn Math: Teaching Mathematics with Seeds and Centimeters
Laura Rickard, Colette Wilson
An agricultural project that teaches sixth-grade mathematics concepts, including measurement and geometry. Sample questions and journal prompts are included, as well as printouts with full descriptions of the process.

Using Engineering to Understand Reciprocal Functions
Janet Sharp, Loren Zachary, Greg Luttenegger
How students investigated numerical data resulting from an engineering experiment as a way to develop understanding of reciprocal functions. Includes sample graphs and project instructions.

Modeling the Seafloor
Kim Clary
A hands-on activity in which students convert decimals to fractions, measure, make scale drawings, use algebraic formulas, and use visualization to construct a three-dimensional physical model of a portion of the seafloor. In the process, they learn about sound, speed, and ocean exploration. Ready-to-print student activity sheets are provided along with solutions.

Integrating Curriculum through Themes
Robert Horton, Traci Hedetniemi, Elaine Wiegert, John Wagner
A strategy that integrates eighth-grade mathematics, science, history, and English through thematic study. Each of the themes used in the South Carolina Studies project focuses on a particular landform region within the state. Includes a sample weekly lesson plan from each content area, one detailed lesson plan, and a student worksheet.
