Virtual math manipulatives are sometimes included in the general academic curriculum as assistive technology for students with physical or mental disabilities. [4] Students with disabilities are often able to still participate in activities using virtual manipulatives even if they are unable to engage in physical activity. [5] [6]
Improvised teacher-made manipulatives used in teaching place value include beans and bean sticks, or single popsicle sticks and bundles of ten popsicle sticks. Virtual manipulatives for mathematics are computer models of these objects. Notable collections of virtual manipulatives include The National Library of Virtual Manipulatives and the ...
A number of compatible shapes that extend pattern blocks are commercially available. Two sets of "Fractional Pattern Blocks" exist: both with two blocks. [7] The first has a pink double hexagon and a black chevron equivalent to four triangles. The second has a brown half-trapezoid and a pink half-triangle.
In the 1980s, Leary became fascinated by computers, the internet, and virtual reality. He proclaimed that "the PC is the LSD of the 1990s" and enjoined historically technophobic bohemians to "turn on, boot up, jack in." [ 142 ] [ 143 ] He became a promoter of virtual reality systems, [ 144 ] and sometimes demonstrated a prototype of the Mattel ...

There are three main types of computer environments for studying school geometry: supposers [vague], dynamic geometry environments (DGEs) and Logo-based programs. [2] Most are DGEs: software that allows the user to manipulate ("drag") the geometric object into different shapes or positions.
An example would be where one is given one positive x 2 tile, three positive x tiles, and two positive unit tiles. The student forms the rectangle by having the x 2 tile in the upper right corner, then one has two x tiles on the right side of the x 2 tile, one x tile underneath the x 2 tile, and two unit tiles are in the bottom right corner.
The two-color system of projection is a name given to a variety of methods of projecting a full-color image using (only) two different single-color projectors. James Clerk Maxwell first suggested he had discovered such a projection system, but it was not reproduced until the 1950s, when Edwin Land accidentally noticed a similar effect while working on his three-color system of projection.
