And then spend the time answering questions about the slope or the point of intersection.Īnd for the teacher, you can prepare several versions of this in advance and use with your classes so they can discover the pattern of slope and perpendicular lines. Instead of students spending precious time actually making a grid on graph paper, plotting points, and using the ruler, they can achieve the result in a few minutes. In the graph below, I typed in a line, added a point, and used the line tool to create a perpendicular line through that point. Geogebra will then create a graphical representation of the equation. To graph an equation, simply enter it into the algebra window and click the “graph” button. One of the most important features of Geogebra is its ability to graph equations. Video of changing the settings and opening the tools. I have them take a screenshot and upload that. I also do not have them turn it in using the GeoGebra interface by saving or turn it in with Google Classroom. I have the students use the text box to include their names and period. When you begin using GeoGebra in your classroom, your first lesson with students needs to include how to adjust the settings (most common problem), the basic tools, and how to use the text box. For example, you can control the range of values that are displayed, the type of graph, and the color scheme. You can adjust the settings of a graph by clicking on the “gear”. I probably use the settings as often as anything else. The gear in the upper right corner is the settings. The basic tools are shown when you load the Geometry version and if you click “more” you get transformation tools as well as construction, circle, and polygon tools. The Geometry version has all the tools you can imagine. The toolbar provides you with quick access to commonly used tools and functions. The graphics window is where you will see the results of your equations. The algebra window is where you will enter your mathematical equations. The main window is divided into three main areas: the algebra window, the graphics window, and the toolbar. GeoGebra’s user interface is designed to be intuitive and easy to use but I find that students still need some basic guidelines to get started. Classic Geogebra can be found at /classic In this blog post, we will focus on the basics and in the coming weeks add some activities you can use in your classroom that have been student tested. GeoGebra has a wide range of features that make it a powerful tool for teaching and learning mathematics. It is available for Windows, Mac, and Linux platforms, and looks great on Chromebooks. GeoGebra is a free and open-source software application for creating and working with mathematical equations and visualizations. It is a free tool that is often underestimated and overlooked, but today we look at some ways we can get started using it in our classroom. I recall one student used a dancing bear and then translated the bear so many times that it was a line of dancing bears.Īnd during distance learning, GeoGebra was a lifesaver because I could not view students manually graphing points or equations. In middle school, I remember using it to demonstrate transformations in the coordinate plane and the kids were so creative. They used their pictures to write the equations of parabolas, and enjoyed it so much they asked for more GeoGebra activities. They uploaded them into Geogebra to visually show the features of a parabola. In my first few years, I had students download images of bridges, rainbows, and fountains. I used it mainly for projects or to demonstrate a specific skill. I have been using Geogebra for most of my 18-year teaching career.
