Suffix Spelling Rules

A reading intervention unit targeting the critical spelling changes that occur at suffix boundaries, designed for older struggling readers. The sequence covers final consonant doubling and silent-e dropping logic.

Unit 9 Overview

An overall curriculum overview and teacher preparation guide for Unit 9 (Lessons 71–78). This resource maps out the core skills, spiral pathways, cumulative benchmarks, and pacing guides for spelling-change rules and alternate vowel patterns.

Suffix Doubling Logic

A structured, age-appropriate reading intervention lesson designed for high school students. This lesson explicitly teaches the 1-1-1 doubling rule when adding the comparative and superlative suffixes -er and -est, while spiraling and reinforcing the doubling rule for -ed and -ing.

Silent E Drop Logic

A structured, age-appropriate reading intervention lesson designed for high school readers. This lesson explicitly teaches the drop-e rule when adding vowel-initial suffixes like -ing, -ed, -er, and -est, while contrasting with consonant-initial suffixes and spiraling the doubling rule.

Y to I Spelling Logic

A structured, age-appropriate reading intervention lesson designed for high school readers. This lesson explicitly teaches the y-to-i spelling change rule when adding suffixes like -ed, -er, -est, and -es, contrasting with -ing suffix addition and spiraling previous spelling rules.

Vowel R Flexibility

A structured, age-appropriate reading intervention lesson designed for high school readers. This lesson explicitly teaches alternate spellings for /er/ (like final -ar/-or in dollar/doctor) and /air/ (like air/are/ear in hair/share/pear), while spiraling and reinforcing standard r-controlled vowel sounds.

Vowel Ear Contrast

A structured, age-appropriate reading intervention lesson designed for high school readers. This lesson explicitly teaches the dual sounds of the 'ear' spelling pattern, contrasting the /ear/ sound (as in dear, hear, near) with the /air/ sound (as in bear, pear, wear) while spiraling prior spelling rules.

Long A Alternate Logic

A structured, age-appropriate reading intervention lesson designed for high school readers. This lesson explicitly teaches alternate spellings for the long /ā/ sound (such as ei, ey, eigh, aigh, ea), while spiraling and reinforcing common long-a spellings like ai and ay.

Spelling Logic Review

A comprehensive Unit 9 review lesson for high school readers. This lesson synthesizes and reinforces the consonant doubling rule, drop-e rule, y-to-i shift, unaccented final -ar/-or, alternate /air/ and /ear/ vowel contrasts, and alternate long-a spellings.

Unit 9 Assessment

A comprehensive Unit 9 spelling and decoding diagnostic assessment for high school readers. It includes student test sections for spelling-change rules, alternate-spelling recognition, sound-sorting, and sentence reading.
