I understand... I will have 2 school age, plus my own 2! The nice thing is they're all very helpful with the little ones. Everyone takes a foot when it's time to put shoes on.

I do a lot of water activities! Slip in slide, sprinker, washing the play equipment. They also enjoy painting and leggo at quiet time. I have a very imagionative bunch, they will play with building blocks and train tracks for hours and hours if i let them!

The older 2 (7 and 8) will go off and make up skits and preformances and preform them for the little kids after quiet time.

We do a lot of trips to the park and the splash pad. Picnics for lunch.

The odd time we'll do movies. They build a fort in front of the tv and go to it!

A lot of crafts! lol The nice things about the older kids is they will often tell you what they want to do based on their interests.

I do not allow hand held game devices. There's too much risk of them getting broken, but my daughter does have an old nintendo in her room that I'll allow for a short period of time.

oh and board games! For rainy days. Go to once upon a child and pick up a few cheap age appropriate board games. Show them how to play it once and they'll pick them up quickly... and puzzles.
