##### NWMC 2013

Apps for presentation entitled "Creating electronic handouts and assessments as browser, tablet or smartphone apps"##### 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.##### Reflections

A collection of examples which explore the properties and uses of reflections and combinations of reflections.##### Proportional Puzzlers

A collection of puzzlers that involve points that are located proportionally by functions or constants on curves.##### 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

##### Wolfram Technology Conference

Apps accompany Phil Todd's presentation: "Symbolic mechanics: from optimal trebuchets to simple chaotic machines"##### 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!##### 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!##### Common Core Nuggets: Conics

This collection contains apps that will help teachers implement Common Core Geometry Standard G-GPE 1, 3 for High School Mathematics.##### 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.##### 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.##### Using Force to Crack Some Geometry Chestnuts

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