Key points
High frequency words are the words that often appear in books, signs, and everyday conversations. The kids who recognize them can develop reading fluency and be more confident. This guide provides definitions, examples, and lists, plus simple ways to practice these words at home.
What Are High Frequency Words?
High frequency words are the words that often appear in written and print materials and everyday speech. They include common words like the, and, of, and it. Because they pop up everywhere, learning to recognize them instantly helps kids read without trouble.
For kids, frequency words provide the basis to build reading fluency, boost confidence, and free up mental energy. So, teachers often define high frequency words by picking ones based on how often a word shows up. As frequency, not difficulty, is the main criterion, the word lists may combine both easy and tricky words.

Examples of High Frequency Words
You can group examples of high frequency words by their function, part of the language, or characteristics. They may refer just to pronouns or auxiliary words, irregular words, conjunctions, or just frequent action words. All of them help keep sentences together.
- Pronouns and auxiliary verbs refer to I, we, they, she, he, be, are, have, had, do, will, can.
- Irregular sight words are said, was, you, of, have, want, they.
- Connectors are concerned with as, by, with, at, of, but, not, up, down.
- Action words are take, go, see, look, make, come.
Here’s how these words work within a sentence: “I can see the dog, and it can see me”. In this example, every word is high frequency, except for the word ” dog “. Seeing high frequency examples like this one can help your child spot the words in books and everyday life.

To use this high frequency word list at home, first print it to be ready to practice a few words at a time. Then, read the list aloud with your child and circle the words that they get instantly. Next, practice the rest first, a few at a time. You can come back to the list every week to make sure kids retain words in long-term memory.
This is just a sample list of high frequency words. Yet, you can combine it with a free reading worksheets that can be printed for practice.
High Frequency Words by Grade
High frequency words change with each grade, offering the basis for kids to develop.
In first grade, high frequency words like said and was show up in nearly every story. By third grade, kids encounter longer sentences and longer words, so grade 3 high frequency words like always and different appear more often.
Here’s a high frequency word list by grade level:
Sample words Typical focus Kindergarten a, I, the, see, and my On the short words kids see on pages often 1st grade are, was, said, have, were, from On the words that won’t follow phonics rules 2nd grade because, before, could, their, would, write On the longer words with tricky spellings 3rd grade always, although, different, together, never, better On the longer connecting words in the texts
When you track progress by grade, you can spot gaps early. For instance, if a child from 2nd grade struggles with first-grade words, it’s a sign to go back and review some words, practice with 1st grade sight words worksheets and 2nd grade reading worksheets, or resort to tutoring to close gaps.
Types of High Frequency Words
High frequency words fall into three types: decodable words that kids can sound out; irregular words that break phonics rules; and heart words that a kid can split into a regular part and a tricky part.
Decodable High Frequency Words
Decodable high frequency words follow standard phonetic rules, where each letter represents its most common sound. Some high frequency words examples include in, can, up, and not.
Teaching kids to blend individual sounds in such words instead of memorizing the word shape strengthens their phonemic awareness. Once they master it, they’ll be able to apply the same decoding patterns to thousands of other regular English words.
Irregular High Frequency Words
Irregular high frequency words contain letter combinations that don’t match the standard phonics patterns taught in early literacy. What are frequency words in this case? Some high frequency irregular words are said, was, they, have, what, etc.
Such words often retain older English language spellings or pronunciations that have shifted over time. Because these words appear frequently in beginner texts yet can’t be fully decoded using basic phonetic rules, they require targeted practice and frequent repetition.
Heart Words
Heart words are high frequency words that have at least one irregular letter-sound pattern, so kids learn this part ‘by heart.’ Most of the word still follows phonics rules. Only the tricky part, called the ‘heart part,’ requires extra memorization.
The ‘heart word’ method is a practice used to teach high frequency words with irregular spellings, in particular those that aren’t fully decodable. This approach requires a child to use their phonics knowledge for the parts of the word that follow standard rules and specifically identify those parts that don’t.
For example, in the word they, the th is a regular sound, but the ey is the ‘heart part’ that is spelled irregularly and which beginning readers must learn by memory. When a kid learns a word this way, the total memorization load reduces, while the child focuses on specific letter-sound mismatches.
Dolch vs. Fry
When you start figuring out what a high-frequency word is and what lists exist out there, you’ll likely come across two famous names – Dolch and Fry. These are the two most common lists used by teachers in American schools to track which words kids should know by heart.
Dolch high frequency words Fry high frequency words List Created in the 1930s, it includes 220 ‘service words’ (like and, the, and is) and a separate list of 95 nouns. First collected in the 1950s (and updated in the 1980s), it contains 1,000 words! They are ranked in order of how often they appear in all types of reading. Goal These words are usually broken down by grade level, from Pre-K to 3rd grade. The idea is that these words make up 50% to 75% of all the text your kid will see in their early school years. These are broken down into groups of 100. The ‘First 100’ are the most important for a beginning reader to know, because they make up about half of everything we read in the English language.
Sight Words vs High Frequency Words
While many people use these terms interchangeably, they aren’t identical. High frequency words refer to the most common words in English, based on how often they appear in print. Sight words are any words a kid recognizes instantly without needing to sound them out.
The answer to the question, ‘Are high frequency words the same as sight words?’, lies in considering a goal versus a result.
- High frequency words are the ‘What’. These are the specific words found on lists like Dolch or Fry. Some are easy to sound out (like ‘in’), while others have ‘tricky’ spellings (like ‘was’).
- Sight words are the ‘How’. It describes a child’s ability to see a word and know it immediately. And a sight word can be anything! If your kid, for example, loves dinosaurs and knows the word ‘T-Rex’ just by looking at it, that’s a sight word for them, even though it isn’t a high frequency word.
The ultimate goal of reading instruction is to turn those high frequency sight words into permanent memories. When a kid doesn’t have to stop and decode ‘where’ or ‘there,’ they have more ‘brain power’ left over to understand the meaning of the story.
Why High Frequency Words Matter
As the 2024 article on the CPB Sight Words provides, your child will meet the same 100 to 300 words
Recognizing these words instantly allows your kid to read smoothly without stopping to sound out every single word. Hence, they’re important for kids to avoid choppy reading and help focus on what the story is actually about.
So small words yet carry so much weight! If we once again have a look at the high frequency words definition – i.e., words that appear most often in our written and spoken language – we’ll realize they are everywhere!again and again, and they will make up 50-70% of everything they read.
Boosting Reading Fluency
Fluency is the ability to read with speed, accuracy, and proper expression. When a kid can look at a word like ‘because’ or ‘there’ and know it instantly, they don’t get stuck. No more ‘reading fatigue,’ where a child gets so tired of decoding sounds that they want to give up.
Guiding Toward Better Comprehension
How will you react to trying to watch a movie where the screen freezes every five seconds? You’d lose track of the plot, right? That’s almost the same as what reading is like for a kid who hasn’t mastered high frequency words. Recognizing them on sight frees their brain to think about the meaning of the sentence.
Improving Writing and Spelling
Once mastered, your kid will start to use them more naturally in their own writing. They won’t have to ask ‘How do you spell friend?’ every time they write a letter, for instance. Expressing their ideas will certainly become much more fun and less frustrating.
Note: You’ll start noticing high frequency words everywhere! On cereal boxes, street signs, and even in your text messages. Pointing them out in the ‘real world’ shows your kid that what they are learning is actually a superpower they can use every day.
How to Teach High Frequency Words: A Quick Overview
To teach high frequency words effectively, you should make learning a regular practice and mix it with activities that involve seeing, saying, and writing each word. The great habits that work for families are:
- Start small and keep it regular. Focus on two or three words at a time, then review them often. Kids need practice before a word feels automatic.
- Back practice with printable materials. For children, it’s important to learn via tracing and writing, and reading worksheets often provide such activities.
- Keep learning hands-on and playful. Also, make learning diverse by adding techniques such as arm tapping or air writing, and incorporate games like Word Scavenger Hunt or Word Bingo.
- Match a method to your child’s style. As the kids have different learning needs, you may need to adjust learning and activities to their style so it clicks and information is retained.

Frequently Asked Questions
How Many High Frequency Words Should a Kindergartner Know?
No national guidelines outline a specific number. Yet, most students in kindergarten aim to learn between 20 and 50 high frequency words by the end of the year. The children often start with words like a, the, and see, and later switch to lists, like the Dolch Pre-Primer, or set the higher target of 100 words.
Do All High Frequency Words Have To Be Memorized, or Can Some Be Sounded Out?
No, not all high-frequency words need to be memorized as whole units by the children. A significant portion can be sounded out (decoded) with the regular phonics rules in mind. Sure, tricky parts in the irregular words may require memorization. However, it would be wrong to treat all high frequency words as undecodable. The recognition of the words happens thanks to orthographic mapping, while decoding develops better readers.
At What Age Do Kids Typically Start Learning High Frequency Words?
Kids typically start learning high-frequency words at the age of 4 or 5, when they are in pre-K or kindergarten. At this stage, they begin recognizing simple sight words like is, it, my, see, we, as they learn sounds and basic phonics. At ages 5 to 7, when the children are through kindergarten and first grade, they have a formal introduction to reading fluency.
Why Don’t All High Frequency Word Lists Use the Exact Same Words?
High frequency word lists use different words as they may follow different methods, source data, criteria, or goals. Classic lists would rely on older samples; for instance, Dolch lists come from the 1930s, and contemporary ones will try to reflect modern vocabulary. So, the collection and definition of high frequency words change a bit. Some lists would include inflections, while others would focus on root words. Lastly, instructional philosophy also plays a role, so certain lists may focus on memorization rather than decoding.
Is It Normal for My Child To Forget a High Frequency Word They Already Learned?
Yes, if your child forgets a high frequency word that they learned, it’s normal. It’s a common part of learning, especially when it comes to irregular words. New words often require multiple encounters before they move into permanent memory. At the same time, the reasons may refer to a lack of orthographic mapping, a lack of practice or connection with a word, and cognitive fatigue.
What’s a Quick Way To Practice High Frequency Words at Home?
A quick way to practice high frequency words at home is to use games like Door Word or Hopscotch. You can also pick two tricky words a day by tracing them with a finger and spelling them aloud. For such an activity, 5 minutes a day may be enough. The other quick home activity refers to the word method, when you say the word out loud and tap out the phonemes, write letter-sound matches, and put a heart over tricky parts to remember.
What Are the First 10 High-Frequency Words?
The first 10 high-frequency words may vary depending on the method or data the list uses. In general, the list will cover the words the, of, and, a, to, in, is, you, that, it. However, a different example of high frequency words would use “I” or “he” instead of “you.”
