Rangoli based symmetry exercise - An activity based on Rangoli Patterns to provide opportunities for illustrating reflective and rotational symmetry of order 4.
"Draw with ribbons of colourful light and make beautiful pieces of digital art. Try making fantastical creatures out of light, or explore symmetry in maths."
Children (and most adults) love looking at themselves on a webcam and this flash based site lets you add over 70 filters and effects. Use the snapshot button to grab an image. There are lots of ways to use this tool in class. Use the mirror functions in maths for symmetry and compile a music video by adding a screencast tool.

the basic tenets of design into two categories: principles and elements
the principles of design are the overarching truths of the profession
the elements of design are the components of design themselves, the objects to be arranged.
principles
Balance
Rhythm
Proportion
Dominance
Unity
Balance is an equilibrium
visual weight within a composition
Symmetrical balance
When symmetry occurs with similar, but not identical, forms it is called approximate symmetry
Symmetrical balance is also known as formal balance.
ntral axis.
Asymmetrical balance
tend to have a greater sense of visual tension. Asymmetrical balance is also known as informal balance.
Rhythm is the repetition or alternation of elements
Regular
Flowing
Progressive
relationship in scale between one element and another,
Proportion is the comparison of dimensions or distribution of forms.
Dominance relates to varying degrees of emphasis in design
visual weight
three stages of dominance
Dominant
Sub-dominant
Subordinate
unity describes the relationship between the individual parts and the whole of a composition
Gestalt theories of visual perception and psychology, specifically those dealing with how the human brain organizes visual information into categories, or groups
Closure is the idea that the brain tends to fill in missing information when it perceives an object is missing some of its pieces.
Continuance is the idea that once you begin looking in one direction, you will continue to do so until something more significant catches your attention
Items of similar size, shape and color tend to be grouped together by the brain, and a semantic relationship between the items is formed.
In addition, items in close proximity to or aligned with one another tend to be grouped in a similar way.
Contrast addresses the notion of dynamic tensionÔthe degree of conflict that exists within a given design between the visual elements in the composition.
The objects in the environment represent the positive space, and the environment itself is the negative space.
The rule of thirds is a compositional tool that makes use of the notion that the most interesting compositions are those in which the primary element is off center.
The visual center of any page is just slightly above and to the right of the actual (mathematical) center.
sometimes referred to as museum height.
The principles of design are the guiding truths of our profession, the basic concepts of balance, rhythm, proportion, dominance and unity. Successful use of these core ideas insures a solid foundation upon which any design can thrive.
