How can I find a template board that is NOT part of the template gallery

Question

As a start for a school project I set up an (SCRUM) board, made it a template, made it public. But my students cannot find my template, although they have the exact name of the template.
It seems the search bar only searches within the template gallery. No problem, as my template is only intended for a small group of students. But how can they find my template when it is set to public but NOT part of the gallery?

I believe that public templates are for members of a workspace. To make it available to public you have to follow another route.

Thank you Alex. This is a possible work-around. It is not though what is promissed by the idea of a template.

Once I create a board, then make it public, then create a (public) template from it. Then others on the internet should be able to find that template, is it not ?

Sadly, that doesn't seem te be the case.

I had already implemented the suggested solution, with a twist. I added my students to my board but as observers. Then told them to copy the board. No need for me to make a copy of my board, since the students cannot change the board as observers.

Question1: is there any use in creating a public template? 
Question2: What would be the benefits of a public template over the above solution?
