The Penguin unit was done in the midst jet lag...so I was surprised that we could finish school at all. Also, one day was stopped for " 100 day " We love the books, esp the Emperor's egg (very easy to read and informational). The kids love "Tacky" too (I'm fine with it) The littlest has been very fussy during school time lately. She wanted my attention and it made school time difficult. So, that day, I decided to put her at the table and gave her book and crayons and paper. So, she actually sat through school time with us. Ha. No fuss anymore. =)
