Recommended for K - 5th, this generator is part of our Vocabulary collection. Children work out what words mean and how they are built: opposites and word groups, words with two meanings, shades of meaning, context clues, synonyms and antonyms, homophones, dictionary skills, similes and idioms, prefixes, suffixes, root words, and Greek and Latin roots. Every word on a Kindergarten or 1st grade sheet is one a 1st grader can read. Prefix, suffix and root word worksheets for K to 5th grade: word endings, prefixes and suffixes with their meanings, root words, compound words, and Greek and Latin roots.

How to use these worksheets

Read Kindergarten sheets aloud: each one is made to be read to the class.
Do the first row together, then let children finish the sheet on their own.

For parents and at home

Ask your child to tell you what a word means in their own words.
