Blue's teacher Miss Marigold has a whole checklist of places for you to visit â?" the Grocery, Present and Music Stores, the Bakery and the Library â?" to show that learning does not stop outside of school! Each place has something special for Blue and you to bring back to Circle Time in Blue's Clues Preschool. Periwinkle is nervous about going to school and to help him overcome his fears, Blue and Joe transform Blue's house into a pretend kindergarten classroom where the games are all about science, telling time, rhyming, art, creativity, math and more in Blue's Clues Kindergarten.
