After students work with land and water materials in the classroom they can use this work to make their own book of the definitions. This is wonderful for students who want their writing to look good but have not yet perfected formation skills. Tracing gives these students great comfort and allows them to do work in a way that makes it possible and successful. Students who do not need to trace can copy a tracer version. This book includes 32 subjects and includes archipelago, canyon, gulf, lake, river, swamp and valley.
