Curated OER
Geometry and Symmetry
Students examine tessellations and their geometric properties. The lesson plan and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.
Curated OER
Reflections of a Quadratic Function
Students are asked to explain the relationship between f(s) and f (-x). They are asked to determine how the equation of f(x) differs from the equation of f(-x). Students determine the conditions when f(x) is the same as f(-x). They graph...
Curated OER
Harvesting and Threshing the Seed
Students harvest and thresh the seeds. They count the seeds and compare that number with the original number of seeds planted (8) to determine their profit or loss. Finally, students think about additional questions they have about...
Curated OER
Unifying Unlike Denominators
Students play roll of fictional radio disk jockeys. They allocate their daily program time into fractional time slots for the playing of specified catagories of music and commercial advertisements.
Curated OER
Middle School Home Energy Audit
Seventh graders research the origins of local electrical power and compare costs and methods of generation with other areas of the country or world.
Curated OER
Pythagorean Theorem Proof
Tenth graders investigate the Pythagorean Theorem. Then they type up a formal paragraph proof of a proof of their choice.
Curated OER
Paper Packaging Design
Students discuss the relationship between technology and manufacturing. They then use their ideas to construct a model of a paper board carton package. Next they view a PowerPoint presentation to learn about the history of packaging...
Curated OER
Tantalizing Tessellations - Lesson I
Students complete a chart (KWL) as a pre-assessment, study the history of tessellations (tilings), investigate the properties of tessellations, and make and evaluate photographs of "found tessellations" for a PowerPoint/HyperStudio...
Curated OER
Lines, Rays, Line Segments, and Planes
Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes
Curated OER
Graphing With RXTE
Students use data from the Rossi X-ray Tiiming Explorer (RXTE) satellite to analyze and graph.
Curated OER
Surfing to the Planets on the Internet
Seventh graders explore the planets using computers and other forms of electronic technology. They research data on two planets and compare the data. Students make conclusions regarding the size of their planets. They calculate how long...
Curated OER
Trigonometric Applications Outside the Classroom
Fifth graders describe and demonstrate how trigonometry can be used to find the height of a tall building or tree. They describe and demonstrate how trigonometry can be used to find the height of a high hill, or other high object where...
Curated OER
Angle Pairs
Students practice identifying right, vertical, and adjacent angles using a Smartboard. They then determine measurements of all of the angles when only one measurement is given.
Curated OER
The X-33 and the X-38
Students explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.
