If we are looking for a common time slot to get together with your students, Doodle would help us to find the best time to meet. 
On the website we can create our doodle by typing the name and location of the event. And we can add a note for the participants to see when they get the invitations. In the next step, this scheduling tool asks us to add your potential time options so that participants can vote for the most suitable one. Finally, we can send invitations either through email or sharing the link.
