I use this board with my English language students. We often need to visit specific points of grammar and it's great to have a focal point for these conversations.
Textbooks are great, and there is a world of teaching resources out there, but I struggled to find anything simple and visual.
Any teacher of English should be able to use it to lead students through a discussion of the tenses used in English.
I have separate boards for each of my students, and I copy this "English Tenses" template onto each student's board. That way we can fill in the gaps and annotate the different sections with no need to "clean" the board for the next student.
This template, and others like it, used with the video chat feature in Miro have enabled my lessons to be easy on preparation but really engaging and interactive.
