That's quite a difference in age groups but here's what I'd recommend. Kids that age still like to pin the tail on the donkey pinned to a tree, a piñata tied to a tree branch they can whack with SMALL sticks, a scavenger hunt with adult supervision to read the clues with a basket of treats at the end so nobody gets left out, this one seems to be very popular. Other than that I'd wish you good luck!
Donut relay - each kid holds a drinking straw in their mouth and the idea is to pass the donut around without dropping it or using their hands. Messy but hilarious. Balloons - zillions of things you can do with those. Even if the kids have to pop them by sitting on them. Capture the flag - any cub or brownie scout can tell you how that works. Appropriate if you have a big enough group.
I'm going along with Glis! Water balloons and squirt guns always make kids happy and they have fun with them! Or Nerf guns!

Hopefully anyway. There is always at least one of those Cartman kids at a birthday party who throws a hissy fit over spilled milk. Usually the one who started "it' too.
You know, the kid who cries because the other kids didn't stop when he said pause because he needs to reload.
.make an obstacle course (kids love this) .roller skating .fun races .give each other tattoos (the peel off kind) .frisbee toss .rented attraction (jumping thing, etc) .....or give each kid a smart phone; no one will run off and it will be quiet for the adults.
