We live in the SF Bay Area. We moved here about a year and a half ago, because my husband's company was acquired. I didn't want to leave our old state (Colorado), so I certainly didn't come with a rosy vision of California. That said, I'm really impressed with the opportunities for homeschooling. It is easy to homeschool, and there are a lot of class opportunities for homeschooled kids -- everything from weekly classes at the science museum, out-of-the-box math classes, co-ops, language immersion classes, nature awareness classes, you name it.... The local museums offer free days for homeschoolers. Mass transit is excellent. I much prefer the weather here to the weather in DC. If your husband is in the city, it may be worth considering living on the peninsula, if it is in your budget. We are mid-peninsula, and it is really lovely here. You are not far from the beach, but you don't get the fog. The summers are mild and heavenly. It never gets too hot or too cold. There are a fair number of homeschool groups, especially as you get closer to the Mid-Peninsula and South Bay. The school districts here are very good (all of our zoned schools at our house get a 10 rating on greatschools.com), and there is SO MUCH culture available in the city. :) My husband bike and/or train commutes, and it is not bad at all. :)

Another vote for Sonlight :) I agree that P4/5 can be used for Kindergarten, and then your science is included, too. :) We are using it this year for my 5yo, and it is a great fit. I'm also using higher cores for my older kids, and we really love them.

Mine are 100EZ Lessons and MFW 1st grade

We use zoobuh and really love it. It has great parental control options (you can be sent a copy of every email, OR you can set it to allow emails to go through for people from a whitelist and for the others to go to a queue for approval OR you can have them all go to a queue OR they can all go straight to the kid, etc., etc.) The flexibility is nice and their spam detection is really good.

Yes, I love Tapatalk! :)
