Welcome to the forum Charrdwood, and thanks for the introduction!
Great to see you making the effort to get the kids involved as well! I don't know your exact area, but it's a safe bet that your chances of finding striped bass close to shore this time of year are best at night. During the day, they'll most likely be heading for deeper/cooler waters and out of your reach.
There's a ton of info on this forum, so get familiar with the search tool in the top tool bar and soak it up.
