Have you ever wondered why some of your students breeze through certain words while others seem to get stuck on even the most common ones? Or maybe you’ve noticed conflicting advice about whether to use flashcards for practicing high frequency words? You’re not alone – these terms often get used interchangeably, but understanding the difference can transform how we teach reading.

Let’s break this down together, because it’s actually simpler than you might think.

High frequency words

What Are Sight Words, Really?

The meaning of “sight words” has evolved significantly in recent years. In fact, it’s not what many of us learned in our teacher preparation programs. While we used to think of sight words as those tricky words students needed to memorize by shape or through flashcard drills, we now understand them quite differently.

Here’s the current research-based definition: a sight word is any word that a reader can recognize instantly and automatically, without having to sound it out. I love how literacy expert Heidi Jane puts it: “A sight word is any word that you can read effortlessly and automatically, without sounding it out or guessing.”

Think about it this way: when you’re reading this blog post, you’re not stopping to decode each word. That’s because these words are all sight words for you – they’re stored in your brain through a process called orthographic mapping. (Don’t worry if that term is new to you; what matters is understanding that our brains can store thousands of words this way!)

What About High Frequency Words?

High frequency words are simply the words that appear most often in text. Think about words like “the,” “and,” “or,” and “is.” These are the workhorses of our language – the high frequency words students absolutely need to know to read even the simplest books fluently.

You might be familiar with lists like Dolch or Fry words. These lists identify the most common high frequency words in children’s books, and while some of these words are irregular (like “the” or “of”), many follow regular phonics patterns that students can learn to decode.

Here’s Where It Gets Interesting (and Practical!)

The big shift in our understanding is this: we want all high frequency words to become sight words eventually, but we don’t get there through memorization. Instead, we help students understand the sound-spelling patterns within these words.

Here’s what this means for your classroom:

When teaching high frequency words with regular patterns, treat them like any other decodable word. Take “and” for example – students can use their knowledge of short ‘a’ and consonant sounds to decode it. No need for memorization!

For those truly irregular high frequency words (like “the” or “of”), you might need to teach them directly, especially in early kindergarten. But keep this list short – research shows that while memorization can work for a handful of words, it’s not effective for the thousands of words we want students to read automatically.

A Practical Tip to Try Tomorrow

Here’s something you can implement right away: When introducing new high frequency words, group them by similar patterns. For instance, if you’re teaching words where ‘s’ makes the /z/ sound (like “is,” “has,” and “his”), teach them together. Instead of presenting each as an exception, help students understand that ‘s’ can represent the /z/ sound in certain words. This approach builds pattern recognition rather than relying on memorization.

Building Success Step by Step

I recently worked with a second-grade teacher who was frustrated because her students could read high frequency words on flashcards but stumbled over the same words in text. Sound familiar? The breakthrough came when she shifted from memorization to teaching patterns. Within weeks, her students were not just recognizing these high frequency words – they were understanding how they worked.

Remember, author Jan Wasowicz beautifully captured this concept when she said, “Every word wants to become a sight word when it grows up.” Our job isn’t to force memorization but to guide students in understanding how words work. This approach not only helps with high frequency words but builds foundational skills that transfer to all reading.

Making It Work in Your Classroom

Start small. Choose a set of high frequency words with similar patterns and plan to teach them together. Notice how your students respond when you show them the patterns instead of treating each word as a separate memory task. Watch their confidence grow as they begin to understand not just what to read, but why words work the way they do.

What About Those Truly Irregular High Frequency Words?

Let’s be honest – words like “of” and “the” are tricky! For these genuinely irregular high frequency words, research from Colenbrander and colleagues (2020) suggests that some direct instruction may be necessary, especially in early kindergarten. But remember, this applies to just a handful of words, not the extensive lists we may have used in the past.

When teaching these irregular high frequency words, focus on the parts that are regular. For example, in the word “said,” the /s/ and /d/ follow expected patterns – it’s just the middle that’s unusual. This approach, sometimes called the “heart word” strategy, helps students anchor their learning in patterns they already know.

Putting It All Together: A Weekly Plan

Here’s an example of what your week could look like:

  • Monday: Introduce 3-4 high frequency words with similar patterns
  • Tuesday: Practice reading the high frequency words in isolation and in simple sentences
  • Wednesday: Have students sort high frequency words by patterns
  • Thursday: Guided reading with decodable texts featuring these high frequency words
  • Friday: Quick assessment and review of the week’s high frequency words

This simple structure helps students see high frequency words not as random items to memorize but as part of our predictable language system. Even when working with struggling readers, I’ve found this approach builds much stronger word recognition than flashcard drills ever did.

Remember, every word wants to become a sight word eventually – we just need to help our students get there through understanding rather than memorization. By focusing on patterns and connections, we’re not just teaching high frequency words; we’re building readers who understand how our language works.

Let’s keep making these research-based shifts in our teaching, one word at a time. Your students’ growing confidence with both regular and irregular high frequency words will show you’re on the right track!
