Guys, I need your advice.

I have two kids: a boy (11 yo), girl (10 yo).

What they do all day is play Roblox.

I work from home full-time, so does my wife, so we have all-day internet connectivity.

They've been home (Covid-19 lock-down) and schooling online, but lately their schools have been on break.

I need to know what activities I can create into routines for them.
Something that will be fun, interesting and educative and would require minimal supervision from me.

Please help!
