This is the word list dictionary for Horizon's 3rd grade spelling and vocabulary program. The Student Dictionary contains the words presented at that level used in a sentence, the part of speech that it represents, and other forms of the word.

This level (generally grade 3) continues to develop spelling and vocabulary skills through phonetic analysis and handwriting practice. The spelling lists cover consonant blends, long and short vowels, silent endings, -ing endings, plurals, homonyms, irregular verb tenses, prefixes, suffixes, contractions, compound words, and multi-syllable words.

The program consists of 160 lessons for a 32-week academic year. The student book and teacher's guide is sold separately.
