The visual capabilities of computers, digital images, and software make your classroom come alive for 21st-century kids. On the Shoulders of Technology Your Students Can See FartherĪbstract: Let the power of technology bring mathematical insights to your students. Presenters: Jennifer Nickell, Lakota Local Schools, Liberty Township, Ohio Suzanne Rushton, Harper Miami University, Oxford, Ohio and Shannon Driskell, University of Dayton, Dayton, Ohio Activities are aligned with the NCTM Standards and include assessments. Topics will include transformations, quadrilaterals, angle relationships, and more. Using Technology-Based Projects to Foster Geometric Thinking in the Middle GradesĪbstract: Join us to discuss classroom-tested projects that engage students using The Geometer's Sketchpad. Martinez-Cruz, California State University-Fullerton, Fullerton, California Paul Sexton, Buena Park High School, Buena Park, California and Greg Love, Buena Park High School, Buena Park, California Tour de Pythagoras, Archimedes, and Euclid with The Geometer's Sketchpad, Powerpoint, and a Digital CameraĪbstract: We revisit antique (but current) Greek mathematics with modern technology for state-of-the-art teaching and learning of geometry. Presenter: Kevin Thompson, University High School, Normal, Illinois Students can discover and develop trigonometry concepts from graphing, the unit circle, and even polar coordinates. Spinning Around: Using Sketchpad and a Ferris Wheel to Facilitate an Entire Trigonometry UnitĪbstract: By modeling the motion of a Ferris wheel in Sketchpad, an entire unit of trigonometry can be faciltated. Presenter: Audrey Weeks, Calculus In Motion, Burbank, California Topics include limits, derivatives, integrals, related rates, volumes, and much more. Meaning through Motion: Improving Calculus Understanding through Interactive Computer AnimationsĪbstract: Explore interactive computer animations (Sketchpad 4) that greatly improve calculus understanding and literally bring it to life as the study of motion and change. Presenter: Virginia Highstone, York Community High School, Elmhurst, Illinois Projects that foster the emergence of students' creativity will be shared. We will look at big ideas hidden in the Transform menu, take a bug walk, and design with iterations. Other Sketchpad Presentations Transform, Iterate, and Create! Iterate a Tiger? Why Not? Megan Did!Ībstract: Sketchpad gives students chances to preview major mathematical concepts.
Presenter: Michael Serra, Key Curriculum Press, San Francisco, California Nontypical Investigations in Geometry for 2008Ībstract: Can you tile the plane with pentominoes? What is Polya's problem? What are all the Archimedean tilings? What is Pick's formula? If any of these are new to you, come join us as we explore some not-so- typical, cool investigations in geometry. Presenters: Rhea Irvine, Key Curriculum Press, Emeryville, California and Philip Wagreich, University of Illinois at Chicago, Chicago, Illinois Examples will come from Math Trailblazers. Using Sketchpad Activities to Enrich Textbook Lessons, with Examples from Math TrailblazersĪbstract: Explore how dynamic representations help students find patterns and make predictions in both exact and uncertain contexts while laying foundations for multiplicative and algebraic reasoning. Presentation materials: See the talk summary, with downloadable materials. Presenter: Scott Steketee, Key Curriculum Press, Oakland, California See several activities, examine how they improve students' understanding, and receive copies to use with your class. Presentation Materials: Geometry_of_Golden_Ratio.gspĭo the Wave: Trigonometry Comes Alive with SketchpadĪbstract: Trig makes sense and is more fun when students make sinusoids actually wave, combine the waves, and explore real-world applications. Presenter: Andres Marti, Key Curriculum Press, Emeryville, California Examine why the golden cut construction results in the value of the golden ratio and how this value is related to Fibonacci numbers and spirals.
