A set of two authentic English books to stimulate your child's intellectual curiosity! Britannica All New Children's Encyclopedia This is the latest children's encyclopedia, supervised by over 100 experts. You can learn about space, animals, history, and more with beautiful illustrations. The One Big Book (Grade 2) English, math, and science all in one book! It contains over 100 topics and is a perfect authentic workbook for homeschooling or review. [Condition of the product] Both are in very good condition. The encyclopedia is a hardcover and has a substantial feel, making it a wonderful interior decoration piece. Overall, the condition is very good, but there are traces of erased pencil markings on two pages of the workbook (The One Big Book). We have erased them cleanly, so they should be hardly noticeable when used for learning. The other pages have no markings and are as clean as new.
