Heart Words | 100 High-Frequency Words with Sound Mapping | Grade 1

Heart Words: High-Frequency Word Mapping is a word study set for Grade 1: a 33-page classroom material set and a 32-page teacher guide. It covers 100 high-frequency words. Students don't memorize them as shapes. They map each word sound by sound and mark only the part that doesn't follow a pattern they know yet. The teacher guide is long because it holds a mapping key for every one of the 100 words.

Many common words look irregular, but usually only one part is unexpected. In said, the s and the d match their sounds. Only the ai is unusual, so that spot gets a heart and is learned "by heart." The rest of the word is decoded like any other. The set builds this idea in steps. The page One box for one sound shows that sounds and letters are not the same thing, since one sound box can hold one, two or more letters. Our mapping routine sets a fixed order of steps. Then come 25 practice pages with four words each, where students connect pronunciation, meaning and spelling. Five application pages follow: Sentence partners, Meaning matters, Partner cover and check, Find the pattern and a reusable My mapping mat. Hearts are often temporary. Once a spelling has been taught in phonics, the heart can go.

Frequently Asked Questions

What grade and standards does this fit?

It is written for Grade 1. The work sits closest to Common Core RF.1.3g (recognize and read grade-appropriate irregularly spelled words), with links to RF.1.3 more broadly and to the spelling standards L.1.2d and L.1.2e. No alignment or endorsement is claimed.

What is a heart word?

A heart word is a high-frequency word with a part that students can't yet decode with the patterns they know. That part is marked with a heart and learned by heart. The rest of the word is mapped and read like any other word.

Do my students' accents change the mapping?

Sometimes. The teacher guide has a section on dialect, grammar and temporary hearts. It explains how pronunciation affects the sound boxes and what to do when your local speech differs from the key.

Why is the teacher guide almost as long as the student pages?

Most of it is the mapping key. Each of the 100 words has its sound boxes and heart spots worked out, grouped four words to a page to match the practice pages.
