I thought the best way to answer the question was to tell you what we're doing this year. Keep in mind that this is just one way to do it. There are other ways. It looks like there are as many ways to make it happen as there are families in the world.
Also, we have a full-day enrichment program on Tuesdays, and my Big and Middle Lady go to a class outside of the house on Thursday, which is essential to note. When I finish this post, I'll talk about our Thursday plans, too.

But on Monday, Wednesday, and Friday, our day goes like this:
When it's Morning Time in Spanish
Our day starts with Morning Time. Take a look at this post from Pam Barnhill if you don't know much about Morning Time. We spend the first part of the day reading, singing, memorizing beautiful language, writing, and having fun with Spanish vocabulary.

When we're together, this time is all in Spanish. It is a way to start the day with a solid connection to my family and our language. Use this for Morning Time:
Math in Spanish
Morning Time comes right after. Math is a subject that we only do in our bilingual homeschooling. In the beginning, I tried a curriculum in Spanish, but it wasn't a good curriculum for me to follow.

I didn't want to give up the quality of my bilingual homeschooling to do something in our minority language, so I didn't want to do that. There was a way around this.

When I'm not a native Spanish speaker, I use a scripted curriculum to get this to work for me. In other words, a curriculum tells me what I should say during each lesson in writing.

That makes it easy for me to figure out what words I'll need. If I don't know certain words, I look them up and write them down in the manual so that I can move right along when we get to that lesson.

Loop: English Language
When we get up in the morning, we switch to English. If you don't know what Loop Scheduling is, read this post from reading Aloud Revival to learn more about how it works. I spend about 40 minutes a day working on phonics. I also work on Spelling and grammar for that amount of time.

My oldest is in second grade, and I spend 15 minutes with him just working on phonics and Spelling with a lot of attention. It doesn't matter how many 15-minute parts it takes us to finish two lessons from All About Reading.

One lesson from All About Spelling, two studies from All About Reading, then one lesson from Spelling. Wash. Rinse. Repeat. In the middle of our work, the Middle Lady reads to the Little Man (or they play). Then we change.

The Middle Lady is in kindergarten, so we only have time to read All About Reading for 15 minutes this time around. I'll add All About Spelling when her reading gets better. In the middle of our work, the Biggest reads a book to the Little Man, sometimes in English and sometimes in Spanish, to help him learn. Then they start to play.

Susan Wise Bauer has a book called First Language Lessons that we work through for the last 10 minutes of our English Loop. If we don't spend much time on these lessons, we can still move forward each day. Mostly.
Read-Aloud
If you're a teacher, this is one of my favorite parts of the day. The kids pick something from our read-aloud basket, and we find a comfortable spot, often outside, to read together.

When we can, I read to them. Most days, we talk for about 45 minutes. We talk about our history, English literature, and science reading in this place (Spanish Lit is covered during Morning Time).

For history and literature, we use the Tapestry of Grace book list.

History has become a subject that I can't handle in my Bilingual Homeschooling. I'm sure a native speaker could do it, but I've overcome my limitations, and we only study history in English.

There are great book suggestions for each week's theme in the Exploring Nature With Children curriculum. There are a lot of Spanish-language books for the weekly science theme, so we read both English and Spanish books about science every week.
