Boost Vocabulary & Comprehension: Teaching Prefixes and Suffixes Using the Science of Reading

 

Let’s get real, teaching prefixes and suffixes can be a real struggle. But when done right, it’s a game-changer for your students’ reading and vocabulary skills! Research from the Science of Reading shows that teaching morphology (studying word parts) helps kids break down tricky words, improve spelling, and become confident readers. So, if you’re looking for a fun and effective way to teach affixes, check out the ideas below:

Why Morphology Matters (And Why Your Students Will Thank You)

The Science of Reading teaches us that strong readers develop through phonemic awareness, phonics, fluency, vocabulary, and comprehension. In early grades, phonics is the big focus, but by upper elementary, kids need to level up with morphological awareness—understanding prefixes, suffixes, and root words. Why? Because it helps them:

• Crack the code on unfamiliar words

• Grow their vocabulary without memorizing endless lists

• Improve spelling by recognizing patterns

• Boost comprehension by understanding word meanings in context

  
  

How to Teach Prefixes & Suffixes (Without Boring Your Students)

1. Directly Teach Common Prefixes & Suffixes (But Make It Fun!)

Instead of expecting students to “pick up” affixes on their own, explicitly teach them! Start with high-frequency prefixes (un-, re-, pre-, dis-) and common suffixes (-ful, -less, -ment, -tion). Keep it hands-on:

• Introduce the prefix “un-” (meaning not or opposite of).

• Give examples like unhappy, unlock, unclear.

• Let students brainstorm their own “un-” words and use them in funny sentences.

2. Use Multisensory Activities to Make It Stick

Kids learn best when they DO, not just see or hear. Try these interactive ideas:

• Word Sorts: Mix up words with and without affixes—can they sort them correctly?

• Affix Scavenger Hunt: Challenge students to find words with prefixes or suffixes in books or around the classroom.

• Interactive Anchor Charts: Create a giant affix wall where students add new words they discover all year long.

3. Teach Affixes in Context (Not Just on Worksheets!)

Seeing prefixes and suffixes in actual reading makes a huge difference. Use high-interest texts with affixed words and break them down together.

• Example: While reading about weather, stop at “precipitation” and discuss “pre-” (before) and “-tion” (act of).

• Teach kids to slow down and decode words using their affix knowledge instead of skipping over them.

4. Let Students Play With Words

Instead of just memorizing, get students creating and manipulating words:

• Prefix-Suffix Mix & Match: Write root words on one set of cards and affixes on another—how many real words can they make?

• Word Ladders: Start with a root word and add affixes to build new words. Example: act → action → reaction → interactive.

• Morphology Journals: Have students keep track of new words they learn, breaking them into root, prefix, and suffix.

5. Keep Reviewing So They Don’t Forget!

Repetition is key! Try:

• Morning warm-ups with a daily affix word.

• Games like Bingo, Jeopardy, or digital quizzes to reinforce learning.

• Morphology writing challenges, where students must use at least three affixed words in a creative story.

  
  

  In my opinion Collaboration Brings it ALL together!

  We all know kids LOVE to talk...all the time...constantly.  Actually, research says if we harness that love to talk and use it in playful collaborative learning experiences, something amazing happens. Instead of taking up to 400 exposures to teach a new concept, it only takes 10-20.  Now that's a Win-Win.  SO...I have created a Latin prefix/suffix resource that focuses on Collaborative learning and fun activities within the Science of Reading concepts.  Check it out in my store:

Dissecting the Science of Reading!

 

The Reading Wars are on...again! 

Buckle up, the Reading Wars are back! It’s cueing system vs phonics, Fountas and Pinnell vs decades of research. Is your district caught in the crossfire, unsure which way to turn? Some districts are diving headfirst into every Science of Reading program they can lay their hands on, while others are crossing their fingers, hoping it'll all just blow over. Sound familiar?

Here's the question: Does everything have to change?  Are we inadvertently harming our students by clinging to outdated methods? If you've scrolled through those Science of Learning Facebook pages, you'll know the struggle. I've Laughed, cried, and even pulled some hair out after some Facebook sessions. There's real confusion out there.  Do we throw the baby out with the bathwater or what?

Here’s my take:

The Science of Reading isn't about scrapping everything we know. It's about rethinking what we know. It's about recalibrating our approach. Teaching that aligns with the Science of Reading isn’t the same old, same old. Think of reading as a Venn Diagram.  One circle is reading instruction, the other is reading research.  For a LONG time, that little area where the two overlap was empty. Research stayed in the “lab”, teaching went on without it.  That’s finally changed. It needed to change.

That overlap in the Venn Diagram is finally being filled in.  We don’t have to spin our wheels anymore. There ARE strategies that align with how the brain works as it struggles to learn how to read. We CAN use the reading brain to make reading easier for kids.

At this point, I see teaching reading that is aligned with the Science of Reading for 3rd, 4th and 5th grades as falling into three main categories. Think of them as a three-legged stool. 

• Fluency- It's about reading smoothly and accurately. Reading itself isn't a struggle, it's effortless. One way to increase fluency is through re-reading.  Students read a short text a number of times in different ways to increase fluency.  Choral reading, echo reading and partner reading all lend themselves to increasing fluency.

•Word-Work-  Dive into affixes, homophones, phonemic awareness and vocabulary – you name it. Some kids missed the boat on basic phonics; they might need a little extra TLC in small group settings.

• Comprehension- Building background knowledge is key. How can a kid grasp a text about an elephant if they've never laid eyes on one? Summarizing, asking questions, visualizing, these are the holy grails of comprehension.There’s still a place for teaching isolated comprehension skills, in my opinion, but they need to be secondary to research based strategies. This is especially true until end of the year tests catch up to research.  That’s another issue.

And here's the best part – most of this can be done with whole-class direct instruction. No more dividing students into 'can' and 'can't.' That's a bonus in any classroom! 

There’s LOTS more to the Science of Reading than one post can address. but, this is a good starting point.  We can’t upend the apple cart all at once, and keep our sanity.  But, focusing on the “three-legged stool” gives us all achievable goals that are proven by science to help kids read better.  So, keep the baby when you throw out that bathwater, but when research speaks, we all need to listen.
