I bought 10 of these for a class of 7 and 8 year olds. Initially, they hadn't had much experience with using dictionaries. After a few days teaching and practice, they became reasonably proficient. These dictionaries are much better than the usual dictionaries that are found in classes for this age group due to the extensive word list, clear, easy to follow format and the use of examples to illustrate word usage. The language used is not too complex for them, although they do not always understand how to correctly use words they have found. Where an entry has more than one word class, eg verb and noun, this is made clear, eg contract. In conclusion, these are good value and can be used by children from 7-11 years and beyond.
