 Virtual Manipulatives
http://www.dreambox.com/teachertools
DreamBox Learning offers free digital math resources for teachers to use in their kindergarten through secondgrade classrooms. DreamBox Teacher Tools include a variety of lessons using virtual manipulatives, ideas for incorporating the lessons in the classroom and resources to support teachers’ professional development as they use the toolkit. The virtual manipulatives are Webbased tools that help students more easily grasp math concepts in visual terms. The lessons are designed to be successful in a wide range of classroom environments.

Lure of the Labyrinth
Lure of the Labyrinth is a digital game for middleschool prealgebra students. It includes a wealth of intriguing mathbased puzzles wrapped into an exciting narrative game in which students work to find their lost pet  and save the world from monsters! Linked to both national and state mathematics standards, the game gives students a chance to actually think like mathematicians.
 The Mathematics Across the Curriculum Project
http://www.math.dartmouth.edu/~matc/eBookshelf/index.html
The Mathematics Across the Curriculum project at Dartmouth College features an “electronic bookshelf” of materials for teaching math in art, history, literature and music, as well as science, engineering and other disciplines traditionally associated with math. Topics include misleading averages, bar codes, crime statistics, DNA, data analysis, gasoline, music and computers, nutrition, polls, population growth, probability, remote sensing, vaccines—and more.
 Math Open Reference
http://www.mathopenref.com/index.html
Math Open Reference is a free online reference for geometry teachers and students that features animated and interactive drawings to demonstrate geometry terms and concepts. The table of contents on Math Open Reference is divided into four basic categories; plane geometry, coordinate geometry, solid geometry and function explorer tools. Click on any subject in the first three categories to find definitions, examples and interactive drawings. In the function explorer category, users can select linear functions, quadratic functions or cubic functions to explore how changes in variables affect the graphed output.
 Yummy Math
http://www.yummymath.com
The Yummy Math website presents mathematics problems and scenarios based on things happening in the world today. For example, an activity for January 26 has students study historical Super Bowl data to reflect on average (mean, median and mode) losing scores, winning scores and range of scores. They are asked to judge which of these central measurements seems the most meaningful and explain their reasoning. Another activity has students plot the cost of a 30second Super Bowl ad over the past 45 Super Bowls. How has the cost of a Super Bowl ad changed over time? Has it grown linearly? exponentially? Yummy Math lists activities chronologically as well as by mathematics subject area. Two mathematics teachers, Brian Marks and Leslie Lewis, developed Yummy Math and welcome suggestions from other mathematics teachers.
 YouCanDoTheCube
http://www.youcandothecube.com/secretunlocked/solutionstageone.aspx
Teachers who want to include the Rubik’s Cube in classroom lessons can access lesson plans and activities tied to state standards on the website YouCanDoTheCube. On the site, the cube—believed to help develop problem solving and spatial thinking skills—is used in math lessons, helping students visualize fractions, geometry and algebra problems. Download a free, PDF version of the You CAN Do The Rubik’s Cube Solution Guide in English or Spanish.

GeoGebra
This free website helps make the connection between algebra and geometry.

Realworld math
In this website, math teacher Thomas Petra shares practical math lessons, lesson ideas, examples, and downloads, including how to find the volume of the Great Pyramids of Giza, converting currency, working with time zones, and tracking a storm’s progress.

The National Library of Virtual Manipulatives
Utah State University has developed this site to showcase effective visual representations of K12 math manipulatives in geometry, algebra, measurement, data analysis, probability, and numbers and operations.
