When our oldest child was 3 and 4 years old, we let him watch the School House Rock video. It was entertaining, but educational and not just a lot of mindless nonsense purely for the sake of entertainment. When the time came for him to learn the Preamble to the U.S. Constitution, he already knew it! When he was introduced to his times tables and needed to multiply by 3's, he already knew them! He already knew how to count by 5's too! The same thing happened for multiplying by 8's and 9's!! My suggestion to all parents is this, if you let your child watch videos, make sure this is one that they view often! Great job guys!! Happy Home School Mom
