Same goal—instant, accurate reading. Different path: map sounds to spellings and only “learn by heart” the unpredictable parts.
Last updated: September 5, 2025
Sight words (in modern, research-based use) means any word a student can read instantly—after it’s been mapped to memory. Heart words are high-frequency words with one or more tricky spellings students must “learn by heart” after mapping all the regular parts with sounds. Don’t teach giant lists by rote. Teach sounds → spellings → mark only the unpredictable bits with a heart.
“Sight word” is an outcome, not a method. A sight word is any word a student recognizes instantly—because the brain has securely mapped its sounds and spellings (orthographic mapping). This includes regular decodable words (cat, into) and irregular high-frequency words (said, was) once learned.
Heart words are the subset of high-frequency words that contain one or more unpredictable spellings for beginners. We teach them by mapping every predictable part with phoneme–grapheme knowledge and marking the tricky part with a small heart. Example: said — the ai doesn’t make its usual /ā/; students “learn that part by heart.”
Feature | Sight Words | Heart Words |
---|---|---|
Meaning | Any word read instantly (automatic) | HFWs with parts to memorize “by heart” |
Teaching Focus | Orthographic mapping via sounds→letters | Map regular parts; mark only irregular bits |
Examples | and, into, like (once mapped) | said, was, one, of |
What to Avoid | Rote visual memorization without sounds | Putting hearts on predictable spellings |
Goal | Accurate, instant recognition in text | Make tricky spellings stick—then automatic |
Coach’s take: Treat “sight words” as the result of mapping, not a giant guessing list. Your future you will thank you.
Need a custom HFW list (e.g., said, were, does, come, some)? ➕ Build your own ABZ game in minutes and assign it to centers or home practice.
Keep it fast, frequent, and focused on automaticity + accuracy. Use this mini-dashboard:
Measure | Quick Probe | K–2 Target | Frequency | ABZ Tool/Game |
---|---|---|---|---|
Instant Recognition | Read 20 HFWs (1s time cap) | ≥ 90% correct | Bi-weekly | Reading Fruit Ninja |
Encoding (Spelling) | Write 10 target HFWs in dictation | 8+/10 correct | Bi-weekly | Stitch’s Spelling Quest |
Transfer to Text | Read 100-word decodable | ≥ 95% acc. & steady rate | Monthly | Read & Race |
Pro tip: If accuracy is high but speed is low, keep words in spiral review for another week and increase oral→print→text reps.
Yes—but teach each word through sounds→letters first. Use lists for sequence, not for rote visual memorization.
Only the unpredictable graphemes for beginners (e.g., said = s + ♥ai + d). Don’t heart what students can decode with taught patterns.
Immediately. After mapping, place the word in decodable sentences and short texts the same day.
Often yes. A short cycle of map→heart→encode→read closes gaps fast, especially when paired with targeted phonics.
Make it make sense, not magic. Map the sounds, mark the curveballs, and move into text. That’s how “sight words” become truly in sight—and how readers fly.
