In the hub panel, just below where you choose your hub picture, there is room for a teacher’s guide. This is a text that isn’t visible to your students. You can write this text to yourself, for example if you have built a big loop and you want to remind yourself of creating groups for your students to work in at this particular hub, or to remind yourself to create logins for your class for a digital resource to use in this hub. If you choose to share your loop with others in the various Loops libraries it is a very good idea to write a short text in each hub to the teacher who borrows the loop from you. Maybe you have prepared a mini lecture you want to mention or maybe there is a digital resource you want to provide a link for.
