Did any of your children use the Kumon workbooks and like them?
I told myself I probably wouldn't do workbooks / worksheets, but... why not? DD loves doing "flash cards", where I tell her what things are (or she signs to me), and we match words to pictures, and she signs her letters. Workbooks might be fun for her and help her with her fine motor skills.
I'd love to hear opinions and favorite titles.
I think they are fine. But prob. not what I would choose. I love the book Mommy Teach Me by Barbara Curtis. Lots of Montessori activities that IMO are better for fine motor skills. Or you could just check out any of the montessori blogs for lots of great ideas.
