Heart Words: A Structured Literacy Teaching Guide

Rote memorization often fails struggling readers when they encounter words that do not follow standard phonics rules. Traditional sight word lists force children to guess rather than map sounds to letters. This new approach helps students master heart words with confidence.

Many parents wonder how this approach differs from the sight word lists they remember from school. Understanding the science behind these terms is the first step toward helping your child read with confidence. To learn more, we must look at the question, What are heart words? The path begins with

What are heart words?

Heart words are high-frequency words that have some parts that do not follow normal phonics rules. While most of the word can be sounded out. One or more parts must be learned “by heart.” This method helps students learn to read words like “said” or “where” without having to guess. By focusing on the sounds, children can build a strong link between letters and their spoken sounds. This approach helps readers of all skill levels build the skills they need to read fast.

The parts of a heart word

Each heart word has two main parts. The first part is made of letters that follow regular spelling patterns. Teachers call these the “flash” parts because they can be read as fast as a flash. The second part is the “tricky” part. This is the letter or group of letters that makes a strange sound. This part is what a student must learn by heart to read the full word.

For example, look at the word “said.” The first letter “s” and the last letter “d” make their normal sounds. But the “ai” in the middle does not sound like a long “a” as you might expect. Instead, it sounds like a short “e.” In this word, “ai” is the heart part that students need to study closely. Reading Rockets says that finding these tricky parts helps students learn high-frequency words that are not spelled in a regular way.

How orthographic mapping works

Heart words help children use a brain process called orthographic mapping. This is how the brain turns a new word into a “sight word” that it knows at once. Instead of learning how a word looks as a whole shape, the brain maps each sound to a letter or group of letters. This forms a long-lasting path in the mind for fast recall later.

Using orthographic mapping activities is much more useful than simple flashcards. When kids map a word, they connect its spelling, its sound, and its meaning. This deep link makes it easier for them to know the word in a book without having to sound it out every time. This frees up their mind to focus on what the story is about.

Heart words vs. rote memorization

Many old ways teach kids to learn a list of words by looking at them over and over. This is called rote memorization. But this can be very hard for students with dyslexia or other reading struggles. The heart words method is not the same. It uses what the child already knows about phonics to teach the regular parts. Then, it only asks them to learn the small part that is not normal.

Feature	Rote Memorization	Heart Words Method
Learning Goal	Learn the whole word shape.	Map sounds to letter patterns.
Phonics Use	Often ignores phonics rules.	Uses phonics for regular parts.
Memory Load	High, as every word is a new image.	Lower, as only “tricky” parts are new.
Success	Hard for struggling readers.	Proven for all types of learners.

This shift from learning shapes to mapping sounds makes a big difference. It turns reading from a guessing game into a skill built on logic and patterns. When kids learn how to handle teaching irregular high-frequency words, they gain the tools they need for lifelong reading success.

A repeatable routine for teaching heart words

Teaching heart words works best when you use a clear, step-by-step way. This way moves away from rote learning and builds real skills. By using systematic phonics instruction, you help kids see how words work. This set of steps ensures that kids do not just look at a word and guess what it says.

The goal is to help kids store the word in their long-term memory. This mental task is called orthographic mapping. When kids map a word, they link the sounds they hear to the letters on the page. Research shows that finding the regular parts of a word is the first step. Even words with tricky parts usually have some letters that follow the rules.

Start with sounds and mapping

Before you show the child the word in print, start with the sounds. This builds sound skills and gets the brain ready to map. Ask the child to say the word out loud. Then, have them tap out each sound they hear. For example, in the word “said,” the child would hear three sounds: /s/, /e/, and /d/.

Once the sounds are clear, you can move to the visual part of the lesson. You can use sound boxes to help with this. Place a chip in a box for each sound the child hears. This act helps them track the sounds before they ever see a letter. Using heart word cards can also help kids see the difference between sounds and letters.

A simple sequence for success

This set of steps lets you teach teaching irregular high-frequency words with ease. It keeps the focus on the logic of our language rather than the parts that seem odd. Following these steps every time will give your kids a sense of safety and success.

1. Say the word and use it in a sentence. Start by saying the word clearly so the child hears the right sound. Ask them to say it back. Then, give a short sentence to show what the word means.
2. Count and split the sounds. Have the child tap out the sounds on their fingers. They can also use chips to mark each sound they hear. This ensures they know every part of the spoken word.
3. Map the regular parts first. Write the letters for the sounds that follow the rules. For a word like “said,” you would write the “s” and the “d” first. Explain that these letters make the sounds we expect.
4. Find the heart part. Show the child the part of the word that does not follow the rules. In “said,” the “ai” makes the short /e/ sound. Explain that this is the part we must learn “by heart” because it is a surprise.
5. Mark the heart part with a symbol. Draw a small heart above the tricky letters. This visual sign helps the child remember that this spot needs extra work and memory.
6. Read and spell the word. Have the child read the whole word a few times. Then, have them write it down. Using the word in a new sentence or finding it in a book helps lock the spelling into their mind.

Cautions for teaching heart words

While these steps are strong, you must avoid a few common traps. One big mistake is trying to teach too many words at once. Focus on just two or three heart words each week. This keeps the child from feeling too stressed. It also gives them enough time to master each word before you move to new ones.

Also, do not skip the sound-tapping step. It is easy to jump straight to the letters, but the sounds are the base. If a child cannot hear the sounds, they cannot link them to letters. Keep the lesson fast to help them stay on task. Using tools like sand trays can also help them learn during the review phase.

How to review for mastery

Last, make sure you go back to these words often. Mastery comes from practice over time, not just one lesson. Include old heart words in your daily drills. This review ensures that the links in the brain stay strong. It helps the child read the words quickly in any book they pick up.

Heart word examples by difficulty

Teaching heart words works best when you group them by how hard they are to learn. Most high-frequency words are actually regular. In fact, research shows that about 63 percent of common words on the Dolch list can be sounded out using standard phonics rules. By sorting words into groups, you can help students focus their energy on the tricky parts while using their phonics skills for the rest.

Flash words with regular patterns

The easiest group of words to teach are called flash words. These are high-frequency words that are spelled entirely regularly. Words like in, at, it, and can fit this group. Students do not need to learn any parts by heart because every letter makes the sound they expect. Using systematic phonics instruction helps students master these words fast. Once they can sound them out, they can read them in a flash.

Even though these words are regular, students still need to see them often to read them fast. You can use orthographic mapping activities to help students link the sounds to the letters. This process helps store the word in long-term memory. When a word is stored this way, the brain finds it at once without needing to sound it out each time. This frees up space for the child to think about the meaning of the story.

Temporary heart words for new readers

Some words are only heart words for a short time. These are words that follow regular phonics rules, but the child has not learned those rules yet. For a first grader, the word play might be a heart word because they have not learned that ay makes the long A sound. Once they learn that pattern, the word moves from the heart group to the flash group. This is why a structured literacy approach is so helpful. It teaches patterns in a clear order so students can turn more words into flash words over time.

Teachers should track which phonics rules they have taught to know which words are temporary. For example, the word she is a heart word until the student learns the sh sound and the open syllable rule. Grouping these words helps you show students that English spelling is more logical than it seems. It builds their confidence as they see the list of tricky words get smaller as their knowledge grows.

Permanent heart words with tricky parts

The most difficult group contains words with at least one part that is truly irregular. These irregular high-frequency words have sounds that do not match standard rules. In the word said, the s and d are regular, but the ai makes the short E sound. This ai is the heart part that students must learn by heart. Only about 27 percent of common words fall into this truly irregular group.

When teaching these words, you must point out the part that does not follow the rules. For the word from, the f, r, and m are regular, but the o sounds like a short U. Educators at Reading Rockets suggest that students should still use phonics for the regular parts. By isolating the irregular part, you make the task of learning much smaller. Instead of memorizing a whole string of letters, the student only needs to remember one small heart part. This is much more effective than rote memorization for struggling readers.

Classroom activities for practicing heart words

Practical classroom games and tasks help students move new words into their long-term memory. These heart words activities focus on the sounds students hear and the letters they see. Using orthographic mapping activities ensures that students do not just guess based on the shape of a word. Instead, they learn to connect sounds to the specific letters they must know “by heart.”

Sound mapping with heart word mats

You can use a simple mapping mat to guide students through the sound-to-letter process. First, have the student say the word and count the sounds they hear. They can place a small chip or token in a box for each sound. Next, the student writes the letters that match the regular sounds in the boxes.

For the irregular part of the word, the student draws a small heart above the letters they must learn by memory. This visual cue helps them find the “tricky” part of teaching irregular high-frequency words. This method allows students to see that most of the word follows phonics rules. Research shows that identifying irregular parts helps students store the word in their brain. You can find more tips on teaching irregular high-frequency words to help your class.

Multisensory heart word building

Multisensory tasks engage more parts of the brain to help with systematic phonics instruction. Give students sandpaper letters, clay, or salt trays to build their words. As they form each letter, have them say the sound it makes. For the heart part, they can use a different color or place a small heart sticker next to the letter.

This hands-on work builds strong links in the brain for systematic phonics instruction. It moves the word away from simple rote memory and toward deep learning. When students touch and build the letters, they are more likely to remember the spelling later. This approach is a key part of orthographic mapping activities that lead to reading success.

Heart word search and find

A “search and find” activity keeps students active while they practice. Hide small cards with heart words around the classroom or in a sensory bin. When a student finds a card, they must bring it back to their desk and map it on a small board. They say the word, count the sounds, and circle the heart part with a red marker.

Using orthographic mapping activities in this way makes practice feel like a game. It also gives you a chance to check for understanding. You can see if the student can find the right part of the word to mark with a heart. This quick check helps you know who needs more help and who is ready for new words.

How can families practice heart words at home?

Practicing at home helps kids turn new words into sight words. Instead of rote drills, you can use simple steps that match school lessons. A steady plan makes learning feel safe and fun. You do not need a teaching degree to help your child succeed with a homeschool curriculum that follows the science of reading.

Use sound boxes for mapping

Sound boxes help kids see how sounds and letters work together. Draw a few boxes on paper or a small board. Ask your child to say a word like “said” and tap one box for each sound they hear. They will tap three times for /s/, /e/, and /d/. Then, have them write the letters that match the sounds they know. In “said,” they will write “s” in the first box and “d” in the last box. Explain that the middle sound /e/ is the “heart part” because the letters “ai” do not follow the usual rules. This orthographic mapping activity builds a strong bond between the word’s sound and its spelling.

Study words in short bursts

Focus on just two or three heart words at a time. Long lists can feel hard for a child who struggles with reading. Spend five to ten minutes each day looking at the word and talking about the tricky parts. Ask your child why a specific part is a “heart part” to check what they know. Research shows that teaching heart words works best when you show which parts follow phonics rules and which parts must be learned by heart. Keeping the mood light and kind helps your child stay on task and willing to try.

Read decodable books together

Reading words in a story is much better than reading them on a list. Look for books that use the specific words you are practicing. As you read together, point out a heart word and ask your child to find the heart part. This helps them move the word into long-term memory for fast use. When a child can read words without sounding them out, they have more cognitive resources for comprehension. This means they can spend less energy on decoding and more energy on the plot.

Review words often

Kids need to see heart words many times before they become instant. Keep a small stack of cards with the words your child has already mapped. Once a word is easy for them, move it to a “mastered” pile. Bring these words back for a quick check once a week to make sure they stay fresh. Review is a key part of systematic phonics instruction. If your child forgets a word, just go back to the sound boxes and map it again. This cycle of review and help gives them the tools they need to become a strong reader.

How do you choose and review heart words?

Picking the right words

You should pick words that appear often in books and text. These are called high-frequency words. Some of these words follow usual rules, while others have tricky parts. You should teach teaching irregular high-frequency words by looking at what your child already knows about sounds.

If a word follows rules they have not learned yet, treat it like a heart word for now. This keeps the child from getting stuck on words they cannot yet map. It helps to group words by their patterns to see which ones are the best to teach first.

As Reading Rockets says, you should group words to see which parts follow phonics rules. This helps you decide which words to teach as step-by-step phonics lessons move forward. Do not try to teach a huge list all at once.

Pick two or three words each week that the child needs for their current reading. This keeps the work easy and helps the child feel success. Small sets of words are much easier for a child to learn and remember.

Using quick checks

You need to know if the child really knows the words. Use brief checks to see if they can read the words fast. Do not just use a list of words. Ask the child to read the words in a story or on flash cards.

This helps you see if they can use the words in real life. If they can read a word fast without sounding it out, it has become a sight word. Reading words this way saves brain power for knowing the story.

Review should build on what the child knows. This means you should keep old words in the mix while you add new ones. Frequent practice helps move words from short-term memory to long-term memory.

You can use orthographic mapping tasks to help this process. If a child forgets a word, do not worry. Just bring it back for more practice next time. Small, daily sessions work best for most kids.

Responding to errors

When a child makes a mistake, do not just tell them the word. Stop and look at the letters together. Find the parts that follow the rules. Then, find the part that they must learn by heart.

This is the part that does not follow standard phonics rules. By doing this, you show them that most of the word still makes sense. It turns a mistake into a chance to learn how words work for the reader.

Avoid teaching too many words that look the same at once. For example, do not teach “where” and “were” in the same week. This can confuse a struggling reader. Instead, wait until they know one word well before you teach the other.

This way, they can build a strong base of words they know. Clear and simple steps will help your child become a better reader. This helps them gain the skills they need to do well.

Frequently Asked Questions

Why are they called heart words?

These words are called heart words because they have parts that do not follow normal rules. A student cannot sound out the whole word using simple phonics. They must learn the tricky part of the word by heart. Most of the word is still normal and can be sounded out. By looking at the small part that is strange, kids can learn the word faster than if they tried to learn the whole shape at once.

Are all high-frequency words heart words?

No, not all high-frequency words are heart words. Many common words follow normal phonics rules and can be sounded out. These are often called flash words. For example, the word “and” is a high-frequency word, but it is not a heart word. According to Lucky Little Learners, about 63 percent of the most common words can be sounded out. Only the words with strange spelling patterns are taught as heart words to help students learn the tricky parts.

How do I find the heart part of a word?

To find the heart part, first say the word slowly and count each sound. Then, look at the letters used to spell those sounds. If a sound is made by a letter that does not follow a normal rule, that is the heart part. For example, in the word “said,” the “ai” sounds like a short “e.” This is the part that does not follow the rules. Finding these parts helps students use orthographic mapping to store the word in their long-term memory.

How many high-frequency words are irregular?

While many common words can be sounded out, some are not normal. Research shows that about 27 percent of high-frequency words have strange parts that need to be taught. These words appear often in books but can be hard for new readers to decode. Teaching these words as heart words helps students learn the tricky parts without guessing. This method is a key part of systematic phonics instruction because it gives kids a clear way to handle words that do not follow the rules.
