dynamic mathematics software for all levels of education that joins arithmetic, geometry, algebra and calculus. It offers multiple representations of objects in its graphics, algebra, and spreadsheet views that are all dynamically linked. While other interactive software (e.g. Cabri Geometry, Geometer's Sketchpad) focus on dynamic manipulations of geometrical objects, the idea behind GeoGebra is to connect geometric, algebraic, and numeric representations in an interactive way. You can do constructions with points, vectors, lines, conic sections as well as functions and change them dynamically afterwards. Furthermore, GeoGebra allows you to directly enter and manipulate equations and coordinates. Thus you can easily plot functions, work with sliders to investigate parameters, find symbolic derivatives, and use powerful commands like Root or Sequence.

This great maths site has an amazing collection of maths self-marking problem solving questions. Search by age level or topic. This covers both Primary and Secondary levels. Topics include numbers, geometry, algebra, data analysis, probability and more. http://ictmagic.wikispaces.com/Maths

This site is an amazing geometry playground for maths students and teachers. Select points on your screen and connect them up to provide the properties you what. This resource uses HTML5 and works wonderfully across a range of computers, browsers and tablets. http://ictmagic.wikispaces.com/Maths

Can giants exist? This question for middle and high school has students use volume and surface area to determine if giants can exist. This is for geometry. Inquiry based projects can have great results.

A site/app which allows pupils to explore geometry & other maths on a digital geoboard.

Fascinating link and overview of cultural historical view of teaching geometry.

"Italian psychologist Geatano Kanizsa first described this optical illusion in 1955 as a subjective or illusory contour illusion. The study of such optical illusions has led to an understanding of how the brain and eyes perceive optical information and has been used considerably by artists and designers alike. They show the power of human imagination in filling in the gaps to make implied constructions in our own minds. Kanizsa figures and similar illusions are a really useful way to encourage learners to 'say what they see' and to explain how they see it. It offers a chance for others to become aware of the different views available in a diagram and share their own thoughts without the 'danger' of being wrong; many people see different things."

A maths resource for young children where users click on shapes based on descriptions. http://ictmagic.wikispaces.com/Maths

online auto cad software. Good for geometry and other projects

*Need a free NYT account. For much of the last century, educators and many scientists believed that children could not learn math at all before the age of five, that their brains simply were not ready. But recent research has turned that assumption on its head - that, and a host of other conventional wisdom about geometry, reading, language and self-control in class.

Big list of flash-based activities, games, and interactives that work well for use with an interactive whiteboard in a mathematics classroom. Includes many areas of math including geometry, numeracy, fractions, probability, and more.

From addition words and elementary math to geometry vocabulary and every type of number word in between, students can find the right list right here with all the math definitions they need to be successful in math.

Article about Georgia Dept of Ed rollout of common core standards and their self admitted botched rollout of state standards several years back. The worst issue from my discussions with Georgia Public school teachers was the attempt at Math I, II, III, an attempt to combine Algebra, Geometry, Trig and Statistics. Not only did the teachers complain but so did parents. I know of several math teachers who quit over this. This is what happens in experiments like this. Standards sound great but who writes them? What happens when they are cumbersome? Look at technology standards which many (including me) think are way too heavily influenced by industry.

A great resource for showing children angles inside a triangle. Move the corners to see how the angles change for different types of triangles. http://ictmagic.wikispaces.com/Maths
