Set 2 (three puzzles and solutions) Graph paper booklet 1 - isometric dots, tumbling blocks, detached squaresUlam number spiralsMultiplication Table with Star PolygonsEsher-inspired GSP activities
Triangulating Polygonal NumbersCatalan Number TriangleThis file contains data for drawing the Catalan Number Triangle with actual values and the values mod 2.
This file contains the data loaded into TinkerPlots, and shows the 'slanted Sierpinski' fractal
This file displays Pascal's triangle with the middle and adjacent-to-middle terms highlighted.
The discrete logistic population modelThis fathom file implements the discrete logistic population model
The sum of digits raised to themselves, 1-4999This text file contains data for the function that takes a number n, and calculates the sum of its digits, raised to themselves Nested Twisted Squares - GSP IterationSimson Wallace Line and Steiner HypocycloidGambler Fallacy - two Fathom filesHere are two Fathom documents for exploring the gambler's fallacy. The first has the simulation, the second has the simulation along with some tables and plots. Simple Harmonic Motion, Lissajous Figures, Adding SinesThis gsp file includes several constructions involving trig functions and circular motion, as mentioned in this post. Arithmetic, Geometric, and Harmonic Means ConstructionThis gsp file shows a construction for the arithmetic, geometric, and harmonic means of two line segments. gsp fileProcessing code for Scrambler FractalA simple Processing program to draw the fractal described here. Copy and paste from the text file. GSP Hypocycloids and EpicycloidsResource file for this post. GSP Origamics - Turned Up Parts (TUPs)Colourful Multiplication TablesFathom and TinkerPlots files for exploring an mxm multiplication table - see this post. fathom file tinkerplots file Number Spirals and Polygonal Numbers in Fathomfathom (version 2.11) file File for exploring polygonal numbers along a quadratic number spiral, as described in this post. Modeling Phyllotaxis in FathomFile for phyllotaxis-like images as described in this post.
Random Walks in TinkerPlotstinkerplots file A random walks simulation that lets you choose the turning angle. tinkerplots file A random walks simulation where the walker faces only North, South, East or West. See the description in this post.
Conditional Probability Simulation in Fathomfathom file
A simulation that explores the phenomenon of 'false positive' medical tests as described in this post.
Drawing Polygonal Numbers in TinkerPlotsDraws polygonal number diagrams (2-dimensional) as described in this post. Digits of Pi in TinkerPlotstinkerplots fileA pi "quilt" in TinkerPlots, as described in this post.
10000 digits of pi (text file)This is an a format for importing directly into Fathom or TinkerPlots, and was used for this post. Pascal's Triangle in TinkerPlotstinkerplots filePascal Triangle diagram in TinkerPlots, including its modular patterns. Full instructions for how to implement this is found in my April 2009 Mathematics Teacher article. The article is available for download here. Monty Hall in Fathomfathom fileThis is a slightly different from the version described in this blog post. Window Patterns in GSPgsp fileSome examples of "window patterns" as iterations in GSP, as described in this post. Drawing Regular Connected Star Polygons in TinkerPlotsDraws regular, connected polygons of the form {p/q} in TinkerPlots, as described in this post.
A Spherical Tetrahedron ModelA template for constructing a spherical tetrahedron, as described in Wenniger's Polyhedron Models, and in this post.
