Sight words

Sight words and heart words

The Dolch lists, with every word checked: which ones a student can sound out, from which lesson, and which letters need to be learned by heart.

Short answer

Sight words are words a student reads instantly, without sounding out. The Dolch lists hold 220 common ones. Most are not irregular: in our lesson sequence, 198 of the 220 become decodable by sound. Heart words are the ones taught before their pattern, with the irregular letters learned by heart.

What is the difference between sight words and heart words?

Teachers use "sight words" for two different things, and the mix-up causes most of the confusion. One meaning is any word a student recognizes in a flash. Every skilled reader has thousands of those, and they got there by sounding words out correctly a few times until the spelling stuck. The other meaning is a list of common words, like Dolch, that schools ask young students to learn early.

A heart word is narrower. It's a common word taught before the student can decode it, either because its pattern hasn't been taught yet (go, before open syllables) or because part of it never follows a pattern (the ai in said). You teach a heart word by connecting every sound to its letters and marking the odd part with a heart. The regular letters still get sounded out.

That's why each word on these pages carries two facts from our decodability engine: the lesson from which it can be read by sound, and the lesson where it's taught as a heart word, if it is one. Where a word has letters that never match a taught pattern, those letters are shown in the table.

How this list was built

Every word comes from the public-domain Dolch lists (Dolch, 1936 and 1948). We do not use the Fry list. Each word was run through our decodability engine, which checks the word's spelling units against a pronouncing dictionary and against the lesson in which each spelling and sound is taught.

"Readable by sound from" is the earliest lesson at which every part of the word has been taught. "Heart word at" is the lesson where the sequence teaches it as a heart word. Irregular letters are the ones whose spelling and sound the sequence never teaches. Contractions and words missing from our lexicon are marked to check by hand.

Questions people ask

What is the difference between sight words and heart words?
Sight words are words read instantly, or a list of common words to learn early. Heart words are common words taught before they can be decoded, with the irregular part marked and learned by heart. Every heart word should become a sight word; most sight words never need to be heart words.
How many Dolch sight words are there?
There are 220 Dolch service words in five lists (pre-primer 40, primer 52, first grade 41, second grade 46, third grade 41) and a separate list of 95 nouns, 315 words in all.
Are most sight words irregular?
No. In our lesson sequence, 198 of the 220 Dolch service words can be decoded once their pattern is taught. Only a small group, such as said, of, one and laugh, keep letters that never follow a taught pattern.
Should students memorize sight words as whole shapes?
No. Words are remembered by linking their letters to their sounds, a process called orthographic mapping. Even for an irregular word, sound out the regular letters and learn only the odd part by heart.
Why is the Fry list not here?
We publish only lists we know are public domain. The Dolch lists are; the copyright status of the Fry list is less clear, so we leave it out.
