My kids are 7 and 5. She is in first grade and he starts kindergarten next year.
We don't do any extracurricular activities, can't afford them financially or time/travel wise. I can't drive at all anymore so the only way we get around is the rare chance my husband can take us, or when family or friends do.
Play dates with friends and their kids help give them something to do while I mainly rest. This doesn't help at all with housework.

My house tends to slide as far as my work around it. I do my best, but my kids and my husband come first. I make sure they are fed homework done and the attention they need. If the housework slacks too much my hubby helps, he will also help if I ask.
The neighbor girls, who are a little older, are always willing to come over and play/entertain the kids when I really can't do anything.
As far as paperwork, if I don't do it daily when it comes home, I will forget it! Homework is done as soon as she gets home as well. It's the only way I can remember to make sure she does it.
I also help the neighbor girls with math homework when needed. This helps make it not so one-sided that they help me so much!
It really does take a village around here and I'm very thankful that I have a "village" that is willing to pitch in so much. Much more than just the things listed here, but I try hard not to ask too much of anyone!
