GeoGebra

Description

GeoGebra is an advanced math tool for graphing, geometry, algebra, 3D and more.

You can use both the online tools and the offline apps that can be downloaded and installed on your machine.

GeoGebra has the following offline apps:

Calculator Suite (algebra, geometry, 3D graphing, probability and symbolic calculations in one app)

Graphing Calculator (plot data, graph functions, equations and more)

Geometry (create circles, angles, transformations etc.)

3D Calculator (3D functions, plot surfaces and 3D geometry)

CAS Calculator (solve equations, expand and factor expressions, find derivatives and integrals)

Note: All online GeoGebra Apps can be found here

Graphing Calculator

This free graphing calculator allows users to create instant graphs for algebra, geometry, calculus, and statistics.

This tool helps two types of users:

1. Teachers

Instructors of students at multiple grade levels can demonstrate math concepts graphically. Also, students can follow along on their computers, or they can create their graphs.

Teachers can adapt the supporting materials that come with the tool. These are interactive teaching aids that allow learners to manipulate the on-screen images in response to teacher instructions or questions. The online dynamic worksheets will enable the teacher to quiz students as they learn.

2. Presenters

A person who wants to present at a conference or meeting can use GeoGebra to construct visual aids to represent mathematical concepts. This may be useful for those whose graphing skills are rusty. The graphs presented by the tool are aesthetically pleasing and easy to understand.

The tool allows users to create web pages. The resulting web pages are interactive, so the learner or viewer can manipulate values. These can be shared with students.

The interface is clear and straightforward. The user clicks on symbols and values, and the graph grows as the input changes.

A large GeoGebra community offers support and advice for users. There is also a GeoGebra Help Center with instructions, tutorials, and answers to common questions.

The Bottom Line

It is a good starting place for those who want to visualize mathematical relationships.
