Hmmm. What kind of information do they learn from these packets? I'm guessing it would have to be the subject content?
Life is not a textbook (and thank goodness I've never seen a horse is to saddle as ox is to _______ question in my adulthood experience) and I prefer that my kids learn to think outside of the box so that one day hopefully they can solve complex problems. But hey, that's just me. If you think it's a good idea to do test packets all day that's fine with me. That's why I support educational choice in this country.
