All About High-Frequency Words

High-frequency words (HFW) are the words that we see most often when reading English texts; Basically, they’re the words used in the highest frequency.

Some examples of high-frequency words are: but, so, come, the, and, a, me, like, what, and that.

These are super important words for kids to know because they’ll see them all the time! So young readers need to be able to read and spell these words to become fluent.

How To Teach High Frequency Words

Whether a word is perfectly decodable or whether it includes an irregular part, we teach high-frequency words in the same research-based way by using orthographic mapping.

Kilpatrick (2015) describes orthographic mapping as “the mental process we use to permanently store words for immediate, effortless retrieval. It is the process we use to take an unfamiliar printed word and turn it into an immediately recognizable word”.

We orthographically map words by making letter-sound connections. When this happens over and over again, the brain is able to store the word and it becomes a ‘sight word.’

The good news is about 75% of high-frequency words are perfectly decodable, where the sound we hear is represented by letter (or letters) that match the sound.

👉🏼 For example, in the word ‘went’ we hear four sounds. Each sound is represented by the common spelling /w/ = w, /ĕ/ = e, /n/ = n, /t/ = t. Kids who know these letters/sounds should be able to see the letters, say the sounds, and blend the sounds together to read the word accurately.

The other 25% of high-frequency words include irregular spelling patterns that require explicit teaching of that irregular part. (The good news is that most of these words only include one irregular part).

👉🏼 For example, in the word ‘said’ we hear three sounds. The first sound is /s/ = s, /ĕ/ = ai, /d/ = d. Notice how the middle sound we hear – /ĕ/ – does not match the letters we see – ai. This is the irregular portion of the word, and that portion of the spelling must be memorized by heart.

But regardless of whether the word is decodable or has irregular parts, we still explicitly teach the word using orthographic mapping. This anchors the regular portions in the brain and only requires memorizing the irregular portion. Some refer to this as heart word method, where we memorize the irregular parts ‘by heart.’

This is the way to teach irregular words that is scientifically based and most effective!

Using the Flashcards

In the past, kids were handed flashcards and told to memorize these words. Our flashcards are NOT intended to be used this way. Instead, the flashcards are designed for kids to make phoneme-grapheme connections.

We strategically designed the flashcards to include certain elements, which is why you’ll love them!

  • Each HFW is written in large black font that is simple to read.
  • Sound dots are included under each grapheme. These dots provide a visual cue that indicate a sound is needed. Kids can touch the dots, look above at the letter/letters, and make the sound, deepening the phoneme-grapheme connection.
  • Digraphs, vowel teams, r-controlled vowels, and other phonograms of two or more letters are underlined in black and include only one dot underneath. This provides students with a visual cue to remember that these letters represent one sound.
  • Hearts are included above any true irregular part. For example, in the word said, ai will NEVER say /ĕ/, so we included a heart above the two letters along with a pink line underneath the irregular part.

✨ Important: You’ll notice that some parts may be ‘irregular’ for your students. For example, if you have not taught r-controlled vowels, then the word ‘or’ will be totally irregular.

You will notice that the ‘or’ is underlined with one dot (one sound), but there is no heart above it. So with this in mind, we included extra hearts at the end of the resource. This allows you to add the heart to any part you haven’t yet taught.

You can tell kids that it is actually regular, but for now it will have a heart. Then, once it’s been a taught concept, you can remove the heart since the sound matches the spelling.

Why We Love It

This resource is exciting for so many reasons!

💟 It’s engaging multiple senses! Kids will say the sound as they touch the dots, drawing attention to the letters they see while anchoring the phoneme-grapheme connection in their brains.

💟 The flashcards include teaching notes for teachers! We know transitioning from the old way of doing things isn’t always easy. Our notes will help ensure you understand the concepts first and explain things in a way that is easy to understand.

💟 It’s aligned with research rooted in the Science of Reading.

If you haven’t tried this approach to teaching HFW words yet, please give it a go! Since switching to this type of instruction, I’ve seen so much improvement and progress, especially with my struggling readers and those with dyslexia.

In my experience, it’s so much more effective than handing kids cards and telling them to memorize words.

Educational Focus: The flashcards are great for self-studying, group activities, centers, playing games, homework practice, and more. Just be sure you’ve explicitly taught any words with irregular parts before giving them to kids to practice.

More HFW Practice

Kids need lots of explicit practice, exposure, and repetition with these words. In my classroom, we practice HFW in various ways.

We read them in decodable sentences and fun poems. Kids can write and rewrite the words using orthographic mapping worksheets, play spelling games, and more.

The flashcards are the perfect addition to a sound wall. Just include the words underneath the specific vowel sound heard within the word. To make this easy, grab our 3 HFW lists organized by vowel sound.

You can also use our fun Dolch Word Game where kids practice using the words from the primer list within context, or use our Dolch Words Lists, organized by similar sounds.
