Play based kindergartens in Berk/Oak with openings?

My kids have thrived at Berkwood Hedge, not sure what their openings are but their Kindergarten teachers are amazing.  Hanan and Silver are what you hope every Kindergarten team would look like!

Children's Workshop Oakland is amazing for us and has a 5s/TK cohort that they might be able to take her. I'm not sure. You could check it out! https://childrensworkshopoakland.com/ 

EBGIS is play-based kindergarten if you are open to German language, and they often have space for new kids. We aren't there anymore but really loved that school. EBI should also have openings for kindergarten if you are open to Spanish language, but I don't know how play-based Kindergarten is.

High, high recommendation for Walden Center & School in central Berkeley! I've been at the school for a few years, with a 2nd grader & kindergartener. I'm pretty sure there's a spot or two left in the kindergarten class.

The school is a smaller project-based K - 5/6 with a strong focus on the arts (dedicated visual arts, drama, music, and Spanish teachers). Academics are definately strong, but the focus is on actual learning rather than checking a box (no grades, no tests, small classes with lots of teacher attention). The school is also highly focused on socioemotional learning & social justice, with the result being that the kids are fluent on the issues of our time, want to be involved in the community, and also just really kind to each other. I think the biggest point in Walden's favor would be that all the kids I know there love Walden and seem to have really joy-filled hours while they're at school - it's standard that the parents doing pick-up end up standing around chatting with each other for 5 to 10 minutes while we try to gently extract our kids who keep asking to stay longer. What more could you ask for from your kids' elementary school than that kids love to be there and are learning to love school & learning?

Some kindergarten specifics:
The kindergarten classroom is in a small house/cottage on the school campus with its own play structure & sandbox, which gives it a home-y feel for the kindergarten students, while still having them integrated with the rest of the school (K students have 1 - 2 days a week where some of their classtime is combined with the 1st grade & have reading buddies from the 5th & 6th... and in my experience they play widely with students of all ages). There are a lot of toys in the kindergarten classroom (and lots of books as well, in all of the classrooms), and plenty of the day for the kindergarten class has time for free play. Academics are introduced via the children's interests and brought in via projects-based learning. For example, the K class recently put on a short play/musical about bees and their role as pollinators - they read books about bees and plants, wrote short sentences about what they learned about bees (or drew pictures for the students still working on writing fundamentals), developed a storyline that would inform the audience about the science of bees (their role as pollinators, the concerns about colony collapse disorder and what we can do to help bees), and used math (patterns, sizing) to make their bee costumes. The class decided as a group that it'd be a little too scary to perform the play for their parents, so instead the play was filmed and performed for their peers in the first grade, who were a very supportive audience! It was one of the most adorable things I've seen, and there was clearly lots of learning going on with that unit, but in a very play-based way.

I couldn't fit this in anywhere in the above, but I also love that Walden kids (especially the younger ones) seem to run around barefoot on the campus often, and my kindergarter is regularly filthy from playing when I pick her up.
