What Your Child Will Learn
- Identify common prefixes (un-, re-, pre-) in words and explain how they change the base word's meaning
- Recognize common suffixes (-ed, -ing, -ly, -er) and determine how they modify word meanings and parts of speech
- Apply knowledge of prefixes and suffixes to decode unfamiliar words by breaking them into smaller parts
- Match base words with appropriate prefixes or suffixes to create new words with correct meanings
How to Use This Worksheet
- Step 1: Before starting, review the word bank or example at the top of the worksheet together. Point out the prefix or suffix that's highlighted, and explain what it means in kid-friendly language (e.g., 'un-' means 'not').
- Step 2: Work through the first 2-3 problems together as a model. Underline the base word, circle the prefix or suffix, then discuss how the meaning changed. Say it aloud: 'The base word is happy. The prefix un- means not. So unhappy means not happy.'
- Step 3: Have the student independently complete problems 4-12, checking in after every 3 problems to ensure they're identifying word parts correctly. Use questioning: 'What's the base word? What was added? How did the meaning change?'
- Step 4: For problems 13-15, have students explain their answers aloud before writing them down. This builds confidence and catches misconceptions early.
- Step 5: Review the completed worksheet together, celebrating correct answers and using incorrect ones as teaching moments to reinforce the concept.
Tips for Parents & Teachers
Use the 'cover and uncover' strategy: Have students first cover the prefix or suffix with their finger, read the base word, then uncover and discuss how the added part changes the meaning. This helps them see the connection between parts. Common mistake: Students ignore the prefix/suffix and just read the whole word. Addressing this helps them understand that word parts carry meaning.
Create a visual anchor chart together showing 3-4 prefixes and 3-4 suffixes with simple pictures. For example, 'un-' might show a happy face that becomes happy/unhappy. Reference this chart while working through the worksheet so students build automaticity with these common word parts.
Emphasize that suffixes often change how a word is used in a sentence. The word 'run' becomes 'running' (action happening now) or 'runner' (a person). Help students notice these patterns by having them use both forms in simple sentences after completing each problem.
Frequently Asked Questions
Why do prefixes and suffixes matter if students can just memorize whole words?
Prefixes and suffixes are tools that help students decode thousands of new words independently. Once a third grader knows that 're-' means 'again,' they can figure out that 'redo,' 'replay,' and 'rewrite' all mean doing something again. This strategy is much more powerful than memorizing every word they'll encounter, and it builds confidence in reading.
My student keeps forgetting which words go with which prefix. How can I help?
This is very normal for third graders! Start by focusing on just 2-3 prefixes at a time (like 'un-' and 're-') rather than trying to learn many at once. Create silly sentences together using the prefix repeatedly: 'I unpack, I untie, I unfold my clothes.' The repetition and humor help cement the pattern in memory.
What's the difference between prefixes and suffixes, and how should I explain it to my child?
Prefixes go at the beginning of words and often change the meaning in big ways (like 'un-happy' means the opposite of happy). Suffixes go at the end and often change what the word does in a sentence (like 'walk' becomes 'walking' or 'walker'). A simple way to remember: Prefix = PRE (before), Suffix = SUF (after).
Should my student memorize all prefixes and suffixes, or is understanding the concept enough?
At the third-grade level, understanding the concept is the priority. Your child should recognize that word parts have meaning and can change how a word works. Memorization of common prefixes (un-, re-, pre-) and suffixes (-ed, -ing, -ly, -er) will develop naturally through repeated exposure and practice with worksheets like this one. Don't stress about knowing every prefix and suffix yet!
