During COVID-19, while my physical classroom was closed, I made a few math videos to encourage my kiddos.
Name That Number card game
Pyramid card game  

I also created a few "mystery picture" (self-correcting) math coloring worksheets, which you are welcome to use.

During video meet-ups with my class we liked to play "Which One Doesn't BELONG." Most of these came from https://wodb.ca and have just been recreated here using vector graphics, making them scale nicely during a screen-share.
