Teaching Kindergarten Heart Words: A 10-Week Checklist Plan with Color by Code Practice

It is reading group time, and a five-year-old stops dead on the word said. She sounded out the first letter, then stalled — the letters do not say what she expects, and no amount of sounding out will fix it. She looks up, waiting for someone to tell her the word. Every kindergarten teacher knows this moment. It happens with was, with they, with one, with could — words children meet on nearly every page, words that refuse to play by the rules they just learned.

Those words have a name: heart words. They are high-frequency words with a tricky part that cannot be sounded out, and the job is to learn that tricky part by heart. The rest of the word usually follows the rules children already know, so the work is small and specific: find the tricky part, mark it, and remember it. That is the heart of the word, and the idea the whole routine is built on.

This guide is a checklist plan for teaching 60 heart words across 10 weeks, one set of six words per week. It starts with the full map of the words, then a setup checklist to run before Week 1, then the daily routine, a sample week, fixes for the words that get stuck, and ways to adjust for different learners and to bring families along. You can run it as a 10-minute daily routine, as a literacy center, or as small-group intervention. The checklists are the point: print the plan, tick things off, and let the routine carry the teaching.

The 10-Week Map: All 60 Words, Set by Set

Here is the whole journey on one page: sixty words, ten sets, six words a week. Each set mixes words children already half-know with one or two that need real attention. Print this map and keep it where you plan — every other checklist here points back to it.

1. Week 1 — Set 1: the, a, I, is, to, of. The starting line. Short words, big payoff: these six show up in almost every sentence children read.
2. Week 2 — Set 2: his, as, has, said, you, your. Said is the first real heart word for many children — the ai does not say what they expect.
3. Week 3 — Set 3: we, he, she, be, me, do. A friendly set, with do as the one to watch.
4. Week 4 — Set 4: was, are, for, or, from, my. Was is the classic stumbler; children want it to rhyme with has.
5. Week 5 — Set 5: go, no, so, by, they, there. They and there arrive together, which is a gift: teach the pair, not the single word.
6. Week 6 — Set 6: what, who, where, here, one, two. The question words land in one week, and one and two carry the trickiest spellings of the set.
7. Week 7 — Set 7: were, look, put, come, some, love. Come and some share a pattern worth pointing out, and love is a word children want to read.
8. Week 8 — Set 8: have, give, live, does, want, done. Does is the one that stops readers cold — the o does not behave.
9. Week 9 — Set 9: could, would, should, pull, full, push. A family of words with a shared shape; learn one and the others come faster.
10. Week 10 — Set 10: into, about, again, many, any, other. The finish line, with again and many as the last tricky parts to mark.

Notice what the map does not do: it never asks children to learn ten words at once, and it never saves all the hard words for the end. The tricky spellings are spread across the 10 weeks, so every week has one word that needs the heart treatment.

Before Week 1: Your Setup Checklist

Ten minutes of setup saves ten weeks of scrambling. Run through this list once, before the first set goes up. The Kindergarten Heart Words Worksheets includes the 10-week study plan, the teacher guide, the 5-step teaching routine and the two-level differentiation guide ready to print, so most of this list is printing and sorting, not creating.

• Print the 60-word list and mark it up. This is your master list, with every tricky part marked with a heart symbol. Keep one copy at your planning spot and one at the small-group table.
• Print one practice page per word for Week 1. Each page asks children to read the word, color the tricky part, trace it, write it, and finish three lines of handwriting practice. Print a week at a time, not all 10 weeks at once.
• Cut the word cards for Set 1. There are 60 cards in the set, 12 to a page, with the tricky parts highlighted. Cut the first six now and keep the rest in the file until their week arrives.
• Put the I Can Read It! tracker where children can reach it. Each child colors one heart for each word learned, working toward 60. A tracker nobody can see is a tracker nobody uses.
• Decide where the word wall lives. The cards are made for word walls as well as centers and small groups. Six new words a week fit on a small wall without crowding it.
• Choose your level for each group. The color by code mystery pictures come in two levels: Level 1 uses 6 heart words and Level 2 uses 12 with review. Decide now which group gets which level, and write it on your plan.
• Print one mystery picture for the week. The 20 worksheets cover the 10 weeks, and the pictures — a cat, an owl, a fish, a rocket, a turtle, a house, an ice cream cone, a butterfly, a ladybug, a car — give children something to look forward to.
• Print the answer keys in color. The answer keys are full-color, and one key works for both levels. The rest of the PDF prints in black and white, so the keys are the only color printing in the set.
• Read What Are Heart Words? The teacher guide opens with a short explanation of what heart words are. Read it once so your explanation to children stays consistent all 10 weeks.
• Read the 5-step teaching routine and the differentiation guide. The routine is the engine of the plan; the differentiation guide tells you how to use the two levels. Ten minutes with both pages now saves a dozen decisions later.
• Set a time. Ten minutes a day, at the same time, beats a long session once a week. Morning meeting, the start of literacy centers, or the first small group all work.
• Check your printing. The contents page lists everything in the 48-page set. A quick check now beats discovering a missing page on Monday morning.

The 5-Step Routine, One Step at a Time

The teacher guide lays out a 5-step teaching routine, and its named moves are plain enough for a five-year-old to repeat: Read it, Heart it, Trace it, Write it. That leaves a fifth move, and it belongs in your plan even though it is the easiest to skip: come back to the word. A word taught once is a word met once. A word read, hearted, traced, written and then met again in a game, a picture or a book is a word a child owns. Here is how each step sounds, with six new words and about 10 minutes.

Step 1: Read it

Hold up the word card, tricky part highlighted, and read the word together. Then let children read it back. Do not ask them to sound out the tricky part — ask them to read the whole word. "This word is said. Say it with me: said." One quick pass, all six words, every day. Children who can read the word before they write it have a target in mind for every step that follows.

Step 2: Heart it

Point to the tricky part and color it — on the practice page, children color the tricky part themselves. "The tricky part of said is the ai in the middle. Color it red, and draw a little heart over it." The color and the heart are the memory hook: one small part to remember, not a whole word to memorize. Name the tricky part out loud every time. "What is the tricky part of was? The a." Keep it to one sentence per word.

Step 3: Trace it

Children trace the word on the practice page, following the letters in order. Tracing is slow on purpose. It gives the hand the shape of the word while the eyes are still on the tricky part. If a child rushes, ask for one more slow trace with a finger first, then the pencil.

Step 4: Write it

Now the model disappears. Children write the word on their own, then finish the three lines of handwriting practice on the page. Three lines is enough: the first is careful, the second faster, and the third shows what the hand remembers. If a word comes out wrong, do not erase the whole page. Circle the tricky part, say it again, and write the word once more underneath.

Step 5: Come back to it

The fifth move is the return, and it is where the learning sticks. Later the same day, or the next morning, meet the word again somewhere new: a word card in a center, a mystery picture, or a book. The cards and the color by code pictures are built for this. A word met five times in five different places is a word children recognize without thinking, which is the whole point of a heart word.

A Sample Week, Day by Day

Here is what one week looks like when the routine is running. The pattern repeats for all 10 weeks — once children know the shape of the week, you only change the words.

• Monday: Meet the six words. Introduce the set with the word cards. Read each word, heart the tricky part together, and send children off with the first practice page. Checklist: cards up on the wall, tricky parts colored, first page finished.
• Tuesday: Trace and write. A second practice page, or the same routine with the next two words. Checklist: every child traced before writing, three lines finished, tricky parts colored.
• Wednesday: Mix it up. Pull the word cards for a quick center game — flip a card, read it, say the tricky part. Checklist: every child read all six words aloud at least once.
• Thursday: Color by code. Hand out the mystery picture for the week. Level 1 children color with 6 heart words; Level 2 children work with 12 words and review. Checklist: picture finished or nearly, words read as they are colored, answer key checked.
• Friday: Check and celebrate. Quick check: hold up each card and let children read it. Color a heart on the I Can Read It! tracker for every word read, and keep the Heart Word Star certificate in sight for Week 10. Checklist: six hearts colored, shaky words noted for next week, new set ready for Monday.

When Words Get Stuck: Fixes That Fit on a Sticky Note

Some words will stall even with the routine. Most stalls fit one of a few patterns, and each has a small fix.

• The sounder-outer. A child tries to sound out said letter by letter and gets stuck on ai. Fix: cover the tricky part with your thumb, read the rest, then uncover it. "The s and d do what you expect. The ai is the heart part — we just know it."
• The guesser. A child glances at was and says saw, or reads there as they. Fix: slow the eyes down. Point to the first letter, then the tricky part. "Start here. What is the first letter? What is the heart part?"
• The memorizer who forgets by Friday. A child reads the word on Monday and loses it by Friday. Fix: more returns, not more tracing. Flip the card in a center, find the word in the mystery picture, spot it in a book. Three quick meetings beat one long worksheet.
• The could-would-should tangle. Three words that look alike arrive in the same week. Fix: teach them as a family. "Could, would, should — they all end the same way. Learn the ending once." Then practice them side by side on the cards.
• The writer who spells it the way it sounds. A child writes "wuz" for was or "sed" for said. Fix: that is useful information, not a failure. It shows the child is listening to the sounds. Point to the heart part on the card and copy it once, slowly.
• The child who shuts down. A child who refuses the page is usually a child who finds it hard. Fix: lower the demand. One word instead of six, a finger trace instead of a pencil, the easier level of the mystery picture. Come back to the rest tomorrow.

Two Levels, One Lesson: A Differentiation Checklist

The set is built for a mixed class. The mystery pictures come in two levels, and the differentiation guide helps you sort children without sorting them in public.

• Level 1 is the starting point. Six heart words on a picture, the current set only. Give it to children who are meeting the words for the first time or who need a shorter task.
• Level 2 adds review. Twelve heart words, including words from earlier sets. Give it to children who know the current set and need to keep older words fresh.
• Same picture, same lesson. Both levels use the same pictures, so children sit side by side doing the same activity at different depths. Nobody can tell from across the room who has which level.
• Move children between levels by week, not by label. A child who needed Level 1 in Week 2 may be ready for Level 2 in Week 5 — if a child reads all six words on Friday without help, try Level 2 next week.
• For children who need more support: work with three words instead of six, trace with a finger before the pencil, and keep the word card visible while they write. The three-line handwriting practice can be one line on a hard day.
• For children who are ready for more: let them hunt the words in a book, write a sentence with two heart words, or teach a word to a classmate. Teaching is the best review there is.
• Keep the cards in play for everyone. The 60 word cards work in literacy centers and small groups at any level, and the word wall grows by six words a week for the whole class.

Color by Code Without the Chaos

A mystery picture lesson can go two ways: twenty minutes of calm coloring, or twenty minutes of crayon negotiation. A few systems tip it toward calm. The Kindergarten Heart Words Worksheets includes 20 mystery pictures, so the routine is familiar by the second week — but the first week sets the tone. Hand out the picture after the words have been read, not before, so children who have already read the six words color with purpose. Put the code where children can see it without flipping the page. Check with the full-color answer key as you circulate, not at the end, so a wrong color gets caught while it is still one square. Let finished children read their picture words to a partner, and keep the finished pictures: a wall of cats, owls, rockets and ladybugs is a record of 10 weeks of words.

Bringing Families Along

Families want to help with heart words. Send home the finished practice page, not a blank one — families can see the routine and the tricky part their child colored. Show them the tracker: 60 hearts, one per word, is a goal a five-year-old can explain at dinner. Suggest five minutes, not a homework session: read the six cards, find one word in a bedtime book, color a heart. If a family asks how to help with a word their child keeps missing, the answer is the same as in class: say the word, point to the heart part, and meet it again tomorrow.

Frequently Asked Questions

What exactly is a heart word?

A heart word is a high-frequency word with a tricky part that does not sound out the way children expect. The teacher guide opens with a What Are Heart Words? explanation, and the word list marks each tricky part with a heart symbol so children know which part to learn by heart.

How long does the daily routine take?

About 10 minutes a day. The routine is short on purpose: read the words, heart the tricky part, trace, write, and come back to the word later. Short daily practice fits morning meeting, literacy centers, or the first small group of the day.

How many words will children learn?

Sixty words in 10 sets of 6, with one set per week in the 10-week study plan. Each child colors a heart on the I Can Read It! tracker for every word learned, working toward all 60 hearts and a Heart Word Star certificate at the end.

What is the difference between Level 1 and Level 2?

The difference is in the color by code mystery pictures. Level 1 pictures use 6 heart words from the current set, while Level 2 pictures use 12 heart words with review of earlier sets. One full-color answer key works for both levels.

Can I use this for intervention or homework?

Yes. The set suits small groups, intervention, morning work, homework and early finishers, as well as literacy centers. The word cards work for quick one-to-one review, and one practice page at a time makes a manageable homework task.

Do I need to print in color?

No. The PDF prints in black and white; only the answer keys are full-color. Children color the tricky parts and the mystery pictures themselves with crayons or colored pencils, so the pages work on a standard classroom printer.
