While teaching from a far you can still encourage students' good behavior and celebrate their efforts using these digital jars with "emoji marbles". Decide what the marbles represent and then move as many you want "in the jar" to reward good behavior. You can do the weekly or daily reveal of how many marbles students have earned. There are various formats to accommodate your needs. There is a list of ideas for "rewards" and the labels of the jars are editable.
