Is this for all subjects or just certain ones? I love My Father’s World for Kindergarten – it encompasses Bible, Math, Phonics, Science, Art, Music. You could even use it as a letter of the week type program and just do the science, crafts/extra activities. You would have to gather a few books each week from the library, but MFW also sells the complete literature collection, so you could just buy it so you don’t have to. You can sometimes find it used, too, on the My Father’s World Curriculum Exchange group on Facebook.
