Teaching polygons, line segments, area, and/or perimeter? Try stretching virtual bands around pegs on a Geoboard.

Today I will be sharing a step-by-step guide on how to use the Geoboard site. The G Geoboard is an online tool that helps students visualize and explore geometry concepts using a virtual geoboard. This site is created by the Math Learning Center and is a great resource for teachers and students alike.

Step 1: Access the Site

To begin, open up your web browser and navigate to the Geoboard site: Once you have accessed the site, you will see a blank grid with dots on it. This is your virtual geoboard.

Step 2: Create Shapes

To create shapes, click on the dots on the grid to create the vertices of your shape. You can also click and drag to create lines connecting the vertices. You can create any shape you want, from simple triangles to complex polygons.

Step 3: Explore Geometry Concepts

Once you have created a shape, you can use it to explore geometry concepts. For example, you can measure the sides and angles of the shape, and calculate its perimeter and area. You can also explore concepts such as symmetry, congruence, and similarity.

Step 4: Customize Your Geoboard

The Geoboard site also allows you to customize your geoboard. You can change the size of the grid, the color of the dots, and the thickness of the lines. You can also toggle the display of the grid and the axes.

Step 5: Save and Share

Finally, you can save your creations and share them with others. To save your geoboard, click on the "Save" button and give your creation a name. To share your geoboard, click on the "Share" button and copy the link to your creation. You can then share the link with your students or colleagues.

The Geoboard site is a powerful tool for exploring geometry concepts. By following these five simple steps, you can create shapes, explore geometry concepts, customize your geoboard, and save and share your creations. I hope you find this guide helpful and that you enjoy using the Geoboard site in your teaching and learning.
