My 11 year old and I play Yahtzee every night and we love it And my 6 year old and I play Sorry for money (a dime a game lol).

They love to cook with me. Dinner, or muffins, or cookies, or whatever.

We rent movies and pop popcorn and watch them together.

Do they play video games? I've found that we all love guitar hero so we play that together.

We go for a lot of hikes and I take my littler ones to the playground to just play (I really like to swing!)

Going to the library and getting books to read together is fun - or sometimes we will get books on "how to draw" and try to draw the pictures in it.

We homeschool, so I am home with the kids, and we don't have extra money to spend on outings and activities....but all of the things above are free or cheap (except for guitar hero! )

Good luck to you
