This updated dictionary contains more than 30,000 entries and more than 1,000 detailed photographs and drawings, an average amount compared with other titles aimed at this audience. The prefatory material includes an overview and a pronunciation guide. Each word entry includes pronunciation (using simple respelling rather than the symbols of the International Phonetic Alphabet), parts of speech, syllable breaks, and one or more numbered definitions. Some entries have sample sentences written in simple language for the intended audience. A few, such as the one for ain’t, have the usage note “slang.” Cross-references to related entries or to pictures are included where appropriate. The pronunciation table is not repeated on every spread in the dictionary, but this is not necessary since no symbols are used. There are no geographic or biographical entries. Many variations of definitions of entry words are provided (e.g., run has 19 definitions). Current words, such as MP3, social networking, and Twitter, are defined. Throughout the dictionary, word-history, prefix, suffix, synonym, and language-note boxes appear with tinted screens. Sidebars contain extra information and illustrations for terms such as sharks and space shuttle. The reference section provides a thesaurus; guides to grammar, punctuation, idioms, and abbreviations; maps; flags; facts about the 50 states and Canada; a list of U.S. presidents; and more. This section lacks some reference charts, such as weights and measures and time zones, that are usually found in dictionaries for comparable ages. The physical format of the pages is appealing to the elementary user, and the type size is readable. The Scholastic Children’s Dictionary is a good choice for elementary-school and public libraries.
