There are lots of class and House-wide games you can play that are fun for students and that make it easy for them to maintain social distance. Games like Simon Says, Jeopardy, charades, and BINGO are both fun and can be played while students sit or stand at their desks.
Give points out as students win! This is great bonding for students in your House. You can even have students compete in their Houses and then have the winning students from each House compete in the ultimate competition for House Points.
There are many ways to run this reward !
You can even give points to students as they participate.
