Whimsical Clocks Ch.1 Morphing Clock
We begin this collection of weird and wonderful mathematical clocks with the Morphing Clock that changes shape as time passes. The Geometry Expressions file is included so you can see how it was made and make new versions for yourself!
Common Core Nuggets: Building Functions
This collection contains apps that will help teachers implement Common Core Functions Standard F-BF 3 for High School Mathematics.
Common Core Nuggets: Area Formulas 6.G.1
This collection contains apps that will help teachers implement Common Core Standard 6.G.1 for 6th grade mathematics.
Whimsical Clocks Ch4 Kaleidoscope Clock
A Kaleidoscope works as a combination of reflections. Mirrors are typically arranged in an equilateral triangle producing multiple reflections as a symmetric pattern which changes as the triangle rotates. The apps in this collection explain how it's done, and then, of course, turn the kaleidoscope into a clock!
Generalizations of a Theorem from Archimedes Liber Assumptorum
The first diagram is from Archimedes' Liber Assumptorum (book of Lemmas). The later diagrams are generalizations to conics.
Common Core Nuggets: Trigonometric Functions
This collection contains apps that will help teachers implement Common Core Function Standard F-TF 2, 3, 5 for High School Mathematics. Apps with an * indicate that they address the modeling standard.
Common Core Nuggets: Statistics
This collection contains apps that will help teachers implement the Common Core Statistics Standard S-ID 6a, b, c for High School Mathematics.
Common Core Nuggets: Equivalent Expressions 7.EE.1
This collection contains apps that will help teachers implement Common Core Standard 7.EE.1 for 7th grade mathematics.
Wolfram Technology Conference
Apps accompany Phil Todd's presentation: "Symbolic mechanics: from optimal trebuchets to simple chaotic machines"
Whimsical Clocks Ch.3 Binary Clock
Our binary digital clock has 3 sections, red beads for hours, purple for minutes and cyan for seconds. Beads in the up position represent the binary digit 1, beads in the down position represent 0. In addition to the Binary Clock, we've provided a Binary Test app to practice your binary numbers.
Euclids Elements
A selection of illustrations from a few propositions in Books 1, 2 and 6 of Euclids Elements
Creating HTML5 Apps with Geometry Expressions
This collection contains the examples apps that were created for "Creating HTML5 Apps with Geometry Expressions."
Proportional Puzzlers
A collection of puzzlers that involve points that are located proportionally by functions or constants on curves.
Circles, Tangents, and N-gon Diagonals
A sequence of apps exploring some interesting characteristics of odd-sided regular polygons.
Common Core Nuggets: Pythagorean Theorem 8.G.6
This collection contains apps that will help teachers implement Common Core Standard 8.G.6 for 8th grade mathematics.
Reflections
A collection of examples which explore the properties and uses of reflections and combinations of reflections.
Common Core Nuggets: Quadratic Zeros
This collection contains apps that will help teachers implement Common Core Algebra Standard A-SSE 3a for High School Mathematics.
Euclid\'s Elements Books 1-4
Several of these exist already, but these are my favorite apps from the original book. -Andrew
Euclid's Elements-Basic Constructions
These apps are taken from Book I of Euclid\\\'s Elements. Proposition 1 shows how to construct an equilateral triangle. Proposition 2 demonstrates how to create a straight line equal to a given straight line. Finally, proposition 3 teaches how to cut off a straight line that is equal to a given line from a larger line.
Euclid's Elements - Books 1-4 (samples)
This collection features several apps that were created for the electronic book for the iPad that adds interactive diagrams to Euclid’s Elements, a mathematical classic (Available from the iTunes store).
Using Force to Crack Some Geometry Chestnuts
Some apps illustrating Philip Todd's Presentation Using Force to Crack Some Geometry Chestnuts by Mark Levi
Finding the Fermat Point by Physics and by Transformation
These apps accompany the presentation Finding the Fermat Point by Physics and by Transformation in the More Favorite Geometry Proofs session at MathFest 2014
NWMC 2013
Apps for presentation entitled "Creating electronic handouts and assessments as browser, tablet or smartphone apps"
Whimsical Clocks Ch.2 Abacus Clock
Like your hands, an abacus lets you count in fives and tens. The first pair of columns are for hours, the second pair for minutes and the third pair for seconds. The bead at the top of each column counts for 5 single beads. The beads in the main compartment of the left column each count for 10 single beads. The bead in the top compartment, left column, counts as 50.
Creating HTML5 Apps with Mechanical Expressions
This collection contains the examples apps that were created for "Creating HTML5 Apps with Mechanical Expressions."
