Emaze.com is an amazing, new publishing tool that you need to try. I call it a cross between PowerPoint and Prezi. With some great looking templates and cloud based storage, you will be ready to wow your audience wherever you are presenting! There are plenty of education themed templates to choose from plus many other topics.
Users can add a variety of media to the templates including text, images, charts/graphs, videos, and links to web resources. You can also import existing PowerPoints and make them emazing. Teacher and student accounts are available. Note, when using a free account, you cannot make your presentations private, so take his into consideration for privacy and safety with students.
