Dot Voting on Zoom using Google Slides
Have participants all join the Google Slides document and then using pre-made dots, have them place their dots on the pre-written sticky notes to vote. Once everyone has voted discuss results.
Dot Voting on Zoom using MURAL
With all your potential options written on sticky notes in your mural start a dot voting session, where participants will move dots to their chosen sticky. Once everyone has voted (or time is up), review the results. Repeat for additional rounds, removing stickies as you go if desired.
