![]() ![]() View the Sketchpad document for this presentation: "Sketchpad Activities for Young Learners in Hong Kong." Presented at the Hong Kong Polytechnic University, this talk showcases sample activities connecting Sketchpad to Hong Kong's primary school mathematics curriculum, with correlations to units and dimensions across all content strands in levels 1–6. Through a Dynamic Geometry perspective, we develop two particularly satisfying results: Euler's formula in complex analysis and the possibility of tessellations of the hyperbolic plane. "Voyages Beyond the Geometric Plane: Advanced Explorations with The Geometer's Sketchpad." Presented at the Hong Kong Polytechnic University, this talk focuses on how the geometry of the Euclidean plane has served as a model in the development of other mathematical topics at the advanced level. Download: Tessellation Activity Worksheets."Tessellations & Islamic Art." This workshop investigates what types of polygons can be used to tessellate the plane and how Islamic artists have approached their craft. "Go Deeper with Young Learners Using Sketchpad." Presented at the NCTM 2006 Annual Meeting, this talk demonstrates Sketchpad activities that actively engage students with the topics of textbook lessons in a variety of math strands. See a streaming video of this presentation.This talk is available as a video-on-demand file from the Ministry's Web site, where it is posted under Professional References here. The plenary address at the PRISM II conference, sponsored by the Ontario Ministry of Education, focuses on a decade of Dynamic Geometry implementation and insights in Ontario. "Sharing What Works: Dynamic Visualizations in Mathematics." " Dynamic Algebra Software: Bringing Functions Alive with Sketchpad." Presented at the NCTM 2006 Annual Meeting, this talk looks at a number of activities in which the power of dynamic mathematics software gives students the opportunity to vary the variables, generate families of functions, and transform functions. Download: Presentation Sketches (.gsp file).Topics include elementary number theory (multiples, factors, prime numbers, GCDs, Fibonacci numbers, and flower patterns), algorithms, recurrence relations, and Boolean or binary logic. " Discrete Mathematics and Dynamic Geometry." Presented at the NCTM 2007 Annual Meeting, this talk explores connections between Sketchpad's land of continuous geometric transformation and subjects drawn from discrete mathematics, where structures are finite (non-continuous).
