What are heart words?

Definition

A heart word is a high-frequency word with one or more irregular letters that the student learns by heart, while sounding out the regular parts.

The name comes from the habit of drawing a small heart over the tricky letters. In said, s and d are regular, so only the ai gets a heart. The student sounds out what they can and memorizes only what they must.

Some heart words are permanently irregular, like of, was and the. Others are only irregular for now: she has a long e that the student hasn't been taught yet. Once open syllables are taught, she is decodable and the heart comes off.

This approach works better than whole-word memorization because it uses the same mapping that stores every other word. The student still links each sound to its letters; they just note the odd link.

In a lesson

Write was. “Which sounds can you read? /w/, yes. /z/, the s spells /z/ here. The a spells /ŏ/ or /ŭ/ in this word. That's the heart part.” Draw a heart over the a.

Track heart words as their own short list with the date each became automatic. A word read correctly but slowly isn't done yet.
