We are using Speaking Spanish with Miss Mason and Francois as well, all the kids enjoy it (ds7, ds5, dd3), but we don’t move very quickly. We started in September and are only on Series (lesson) 4! We also add in fun Spanish songs on Youtube, like Basho and Friends. I feel like at this stage, we’re enjoying the exposure and maybe we’ll ramp up next year.
So I think the Cherrydale program works with a 1st grader just fine.
And pinkballerina, you are not alone in moving slowly!
