Manipula Math Applet Collection : This applet collection contains many applets that can help teach students different mathematical concepts in trigonometry, geometry, calculus and vectors. The Pythagorean Theorem applets (there are 8) found under "Geometry 2" give many ways to understand the theorem, as addressed in the Common Core Standard CCSS.Math.Content.HSG-SRT.B.4 . As a teacher, I could use this collection of applets to help discover the many relationships that exist in math, particularly geometry.

Java Applets : This collection of applets created by a professor at PLU contains many java applets under many different mathematical subjects. Many are developed for college level math courses, but some can be utilized by Secondary Ed. teachers. One applet, Definition of Trig Functions, can help students discover relationship between the unit circle and the coordinate system graphs of trigonometric functions, as addressed in the Common Core Standard CCSS.Math.Content.HST-TF.A.2 . As a teacher, I could use the individual applets in this collection to help students discover relationships between different mathematical ideas.

Math Applets at SLU : This collection of applets from SLU contains many different applets for mathematics courses below calculus. There are different types of applets, include some created in Geometer's Sketchpad and GeoGebra. One particular applet, Triangle Middle Applet, deals with different theorems about triangles, as addressed by the Common Core Standard CCSS.Math.Content.HSG-CO.C.10 . As a teacher, I can use the applets in this collection to understand theorems, especially theorems that fall under geometry.

Geometry Applets : This collection of applets specifically pertains to geometry and was put together by a Penn State mathematics professor. The applets falling under the first section pertain specifcally to the basics of geometry as addressed by the Common Core Standard CCSS.Math.Content.HSG-CO.A.1 As a teacher, I could use these applets in a geometry class to introduce the basics ideas of geometry.

MathinSite Applets : This collection of applets contains pure and applied mathematics applets. Some of the pure mathematics applets pertain to the graphing of functions. These applets could be used when discussing the differences between linear and exponential functions, as addressed by the Common Core Standard CCSS.Math.Content.HSF-LE.A.1 . As a teacher, I could use the applets in this collection when discussing families of fuctions and applications of these functions.

Specific:

Triangle and Law of Sines : This specific applet helps the user to see the relationships that occur with the Law of Sines. This pertains to the Common Core Standard CCSS.Math.Content.HSG-SRT.D.10 . As a teacher, I can use this applet to introduce the idea of the Law of Sines. Students can see the relationships in many cases before attempting to prove the law.

Snail Shell : This specific applet relates properties of similar triangles to describe snail shells. This pertains to the Common Core Standard CCSS.Math.Content.HSG-MG.A.1 . As a mathematics teacher, I can use this applet to show how similar triangles appear in nature.

Conditional Probability Applet : This specific applet deals with understanding conditional probability. It uses the concept of a Venn diagram and allows for the discover of what conditional probability means. This pertains to the Common Core Standard CCSS.Math.Content.HSS-CP.A.3 . As a teacher, I could use this applet to help students see visually the probability of events, specifically conditional probability.

Vector Addition : This specific applet deals with adding and subtracting vectors. It pertains to the Common Core Standard CCSS.Math.Content.HSN-VM.B.4 . As a teacher, I could use this applet to give students a visual representation of what occurs when adding and subtracting vectors.

Matrix Multiplication : This specific applet displays the multiplication of two matricies and how the rows of the first and columns of the second define the outcome. This pertains to the Common Core Standard CCSS.Math.Content.HSN-VM.C.9 As a teacher, I can use this applet to help students understand the process of multiplying matricies.
