Teachers can use GeoGebra to help make math more meaningful and visual for students. Teachers can quickly build digital worksheets that include simulations already created on GeoGebra and their own multiple-choice or short response questions. Don't have graphing calculators to use while taking paper and pencil tests? Let kids use GeoGebra Exam mode on their handheld device or computer. This runs in full-screen mode, restricting students' access to other programs and the internet during the test. A red header pops up right away if a student tries to open another browser tab.

Make sure to familiarize yourself with the extensive tutorials ahead of time in order to become an expert with the program and its capabilities before attempting to implement it in the classroom.

They drag objects and adjust parameters to explore algebra and geometry simultaneously. Like Desmos, it is both a graphing calculator and a collection of math simulations. GeoGebra offers kids and teachers the option to use existing math explorations or build their own. The existing pool of explorations is vast, so it covers most high school Common Core math expectations, especially those involving graphing or geometry.

Teachers can make their own interactive worksheets that include simulations, videos, text, multiple-choice questions, and more. Teachers can create class groups to quickly share activities with kids. Alternatively, tutorials provide options to let teachers incorporate GeoGebra into their existing class sites or learning management systems.

Traditional methods of performing constructions with a compass and a ruler can be time-consuming and frustrating for kids. GeoGebra makes it quick, easy, and fun as long as there are clear directions. Activities are built and shared by anyone who wants to be an author, so quality varies greatly; some do not provide specific directions for students. But teachers can create their own interactive worksheets that include the simulations built by someone else, along with their own helpful directions or context.

Glitches, such as spam blocking on the GeoGebra end, can frustrate teachers. However, the help desk is quick to respond to questions. GeoGebra is a powerful example of flexibility paired with community. Teachers can make whatever they need for their students. But they don't have to start from scratch -- they can build off of the work of others. This means that math simulations are being built every day by teachers all over the world. Teaching the difference between exponential and logistic models? One teacher shared an activity on the growth of Facebook. Need an analog clock with hands you can manipulate? GeoGebra has one of those, too.
