Text style and size on axis tick marks are adjustable.

Expanded line weights, line strokes, and point sizes allow for age-appropriate sizing of objects.

New nonlinear transformations can be defined and added to the Transform menu.

Multiple transformations can be combined into a single custom transformation.

Angles can be defined by two intersecting rays or segments, and can also be defined to be reflex angles greater than 180° or trigonometric angles (between –2π and 2π radians).

Easily construct polygons and their interiors with the new Polygon tool.

Choose a grid with trigonometric labels, create and listen to dynamic audible functions, and graph parametric functions.

Construct entire families of functions and families of curves, parameterized either geometrically or numerically.

Function plots and loci can be transformed and iterated, and intersections of function plots can be found.

In blank space, you can handwrite text or circle parts of your sketch for emphasis or make a freehand drawing that you can then transform.

Add clarity with angle markers, congruency marks, and parallel arrows.

The Marker tool enhances presentations and facilitates the use of interactive whiteboards.

Mouse over that Hot Text to highlight the referenced object.

Simply click an object to insert its fully mathematically formatted notation (Hot Text) into a caption.Hot Text makes presentations clearer and more effective by dynamically linking captions and the objects they describe.Pictures can be reflected, rotated, dilated, attached to points, cropped to polygons, iterated, used in locus constructions, and more!.Import digital photographs or drag and drop images from a web page into a sketch.Engage students in learning by letting them import and transform any image.For 25 years before joining SRI, Jackiw led ongoing Sketchpad research and design at Key Curriculum Press/KCP Technologies, and coordinated Dynamic Geometry implementation projects with institutional partners around the globe.Īnd you can use the 80 GSP files at Visual Dictionary of Special Plane Curves.

Jackiw is the original designer of The Geometer's Sketchpad, one of the most widely-used, regarded and emulated software tools in education. That research informs his design and development of new learning experiences, situations, and technologies. His research focuses on how mathematical ideas are embedded in, and functions of, the cultural practices and representational technologies of the contexts in which they arise and also on how new technologies and practices imply not just new mathematical representations but fundamentally new mathematical ideas and approaches. Nicholas Jackiw is a senior research scientist in SRI International's Center for Technology in Learning, where his interests focus on how digital technologies can uniquely shape mathematical propositions and learners’ intellectual and material interactions with them. Senior Research Scientist, Center for Technology in Learning Nicholas Jackiw, who wrote Geometer's Sketchpad, seems now work for SRI International. McGraw-Hill, no stranger to dire straits, hopes these tools can jumpstart its own business.

But recent years found the print business struggling, leading to a series of layoffs and restructuring to re-focus on its digital offerings. The Emeryville, CA-based publisher built its brand over the past decades with a series of math texts and materials, along with digital tools like Geometer's Sketchpad and TinkerPlots. KEY CURRICULUM: Acquired by McGraw-Hill Education for an undisclosed amount. McGraw-Hill Education acquires Key Curriculum Most popular is GeoGebra.Īpparently, the company is acquired. By 2010, it's a dime a dozen, most are free. I believe there are also 1 or more Euclidean geometry theorem discovered due to use of such software, but i couldn't find a citation at the moment.īut since 2000, many many interactive plane geometry came up. Was revolutionary in math education, in the 1990s.

Addendum: as of today, it seems not free again.
