A First Grade Teacher’s Guide to Supporting Family Involvement in Foundational Reading Skills
Prefix, Base Word, Suffix
A base word can stand alone and has meaning (for example, help). A suffix is a word part
added to the end of a word (for example, -ful). If you add the suffix -ful to the base word, help,
the word is helpful. A prefix is a word part added to the beginning of a word or base word (for
example, un-). If the prefix un- is added to helpful, the word is unhelpful.
1. Ask your child to read the word.
2. Ask your child to break the word into its word parts (prefix, base word, and suffix) and
write the word parts.
3. Ask your child what the word means. If your child is unsure of the word meaning, explain
the word to your child. Use it in a sentence and ask your child to try to use it in a sentence.
4. Use the blank table to create your own base words with prefixes and suffixes.
