Microsoft PowerPoint is a powerful slide-based presentation tool that can be used by teachers and students as a way of communicating digitally. This comes as part of the Microsoft Office 365 package so, if your institution uses that, you may already have access to this power tool.
This lets you create presentations from scratch or -- helpfully -- using templates that allow you to input the data you need to end up with a professional finish, fast. Since the software is cloud-based, it can allow you to jump between devices while working on a single project that's also easy to access and share.
