Pixabay has been one of my go-to sources of high-quality images for years. The images on Pixabay are in the public domain which makes them perfect for all kinds of classroom projects. You can download the pictures for free from the Pixabay website. But if you or your students are working on on Word documents, the Pixabay add-in for Word makes it possible to find and insert images without having to go to the Pixabay website.
In the following video I demonstrate how to install and use the Pixabay add-in for Microsoft Word.
