Simply check the schedule, pick the district or theme that interests you most, and head to the meeting spot.
If your kids are active and enjoy the outdoors, take them hiking on the coastal trail in the Presidio district. From this trail, you'll get picture-perfect views of the Golden Gate Bridge and of where the bay meets the ocean.

One of my favorite places to take kids is to the large window at the factory, where they can watch bakers mold the dough into crabs, crocodiles, turtles, and more, and see the golden bread animals come out of the oven. It's one of the quick, but fun things to do in San Francisco with kids.
Twin Peaks is an excellent place to visit with kids, as they'll release a lot of energy and have fun hiking up the steep hill from the base of the mountain. It's a beautiful natural area full of local plant and wildlife, but the real prize is getting to the top to soak in the 360-degree views.

The Koret Playground at the southeast corner of Golden Gate Park is a fantastic free place for kids to run around and just be kids.

The area also houses a beautiful carousel with a menagerie of colorfully painted dragons, camels, horses, frogs, and more.
You're in California, so why not head to the beach? You won't always get warm sunny weather at Baker Beach, but you're guaranteed to enjoy the spectacular views of the Golden Gate Bridge peeking out from behind the cliffs and the water where the bay meets the Pacific Ocean.
The kids will love playing in the sand, and if you come by the coastal trail in the Presidio, you'll have extra fun walking down to the beach on the Sand Ladder. This part of SF is tucked away from the rest of the city, making for a nice afternoon retreat.
One of my favorite free things to do in San Francisco with kids is to head over to the park at the Palace of Fine Arts building and have a picnic while taking in the view of the lake, the trees, and the Roman architecture.
This historic building is the only part of the 1915 Panama Pacific Exposition that remains, because it was just too beautiful to tear down. This is a peaceful place to take the family, and it's fun to watch the kids feed the birds and look up in awe at the large ornate columns.
