I have been ruminating on how to teach a foreign language to a 5.5 year old and 2.5 year old, simultaneously, and for free until I order curriculum for next year. I didn't want to have to buy anything right now, and since one of the children is non yet reading it needs to be oral. I did a lot of searching around the internet, and I either found that I will need a curriculum or I'll never do it right, or to just start speaking. Neither was working currently- while I am fully capable linguistically of interjecting French randomly it just didn't seem to be happening.
So! More planning. I think that this way I have a method that will work for me, and hopefully the children. Maybe someday it'll be my super best selling homeschool curriculum of my own... but I don't think so.
I spent time looking at most commonly used words by adults, preschoolers, and toddlers. Lists online abound. There is a lot of cross-over. I like this idea because I get a set number of words, with a sampling of nouns and verbs. It doesn't require reading or writing for my little one, but I can incorporate both for the elder- if I want. I'll also be doing a few verb tenses- mostly present, future, and one past tense.
That's the current plan. If anyone is interested- I can share links for word lists and whatnot.
