##### Circles, Tangents, and N-gon Diagonals

A sequence of apps exploring some interesting characteristics of odd-sided regular polygons.##### 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.##### NWMC 2013

Apps for presentation entitled "Creating electronic handouts and assessments as browser, tablet or smartphone apps"##### 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.##### Creating HTML5 Apps with Geometry Expressions

This collection contains the examples apps that were created for "Creating HTML5 Apps with Geometry Expressions."##### 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!##### Proportional Puzzlers

A collection of puzzlers that involve points that are located proportionally by functions or constants on curves.##### Using Force to Crack Some Geometry Chestnuts

Some apps illustrating Philip Todd's Presentation*Using Force to Crack Some Geometry Chestnuts*by Mark Levi

##### Reflections

A collection of examples which explore the properties and uses of reflections and combinations of reflections.##### 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.##### Wolfram Technology Conference

Apps accompany Phil Todd's presentation: "Symbolic mechanics: from optimal trebuchets to simple chaotic machines"##### 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!##### 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.##### 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.##### 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.##### 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).##### 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.##### Euclid\'s Elements Books 1-4

Several of these exist already, but these are my favorite apps from the original book. -Andrew##### 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.##### 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.##### 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
