The Book of Years, Science Sketch Pad, World Explorer Journal, and Art Sketchbook are interactive journals.  Kids get to create their own book about the things they are learning in Layers of Learning.  They add pictures, graphs, diagrams, foldables, and paragraphs about the civilizations, science concepts, places around the globe, and art they are learning about. The student journals are a terrific way to see the big picture of the story of our world and its peoples.
