I love printables. I think it's the instant gratification of getting something you found online immediately (as long as you have a printer, ink, and paper of course). Here are some fun games and activities I've seen online recently. Keep these on hand for some of those summer "I'm bored" moments.
Slotted Building Discs from Made by Joel
Vintage Battleship Game from Just Something I Made
Bubble Wrap Travel Game from Oh Dee Doh
Summer Reading Log Printables by Rebecca Cooper
