Merriam-Webster's Intermediate Dictionary

Rating:
Summary: Not Only For High Schoolers
Review: This was a required purchase at my son's private school. He is in 5th grade, and this dictionary has proven to be a very valuable resource. The definitions are clear and concise. This dictionary is one that can grow along with him, instead of rebuying the next age appropriate resource. I expect that he will continue to use it for many years.
