Spelling with Structure: Unit 4 – Advanced Morphemes

Take students beyond basic word study with Unit 4: Advanced Morphemes from the Spelling with Structure™curriculum! This comprehensive morphology unit provides explicit, systematic instruction in advanced prefixes, suffixes, Greek bases, Latin bases, and assimilated prefixes to strengthen spelling, vocabulary, decoding, encoding, and reading comprehension.

Built on the principles of Structured Literacy and the Science of Reading, this resource helps students recognize meaningful word parts so they can confidently analyze unfamiliar words, improve spelling accuracy, and deepen vocabulary knowledge across all subject areas.

Throughout this unit, students learn how words are constructed by combining meaningful morphemes, making connections between spelling, meaning, and language structure.

This unit teaches:

• Prefixes over- and under-

• Prefixes inter- and trans-

• Greek base micro

• Latin base scrib/script

• Suffixes -ful and -less

• Suffixes -ive and -ness

• Prefixes mis- and mal-

• Latin base ject

• Greek base ortho

• Prefix sub- and its assimilated forms (suc-, suf-, sug-, sup-, sus-)

Students learn to apply these morphemes while reading, spelling, writing, and analyzing increasingly complex words.

Every weekly lesson includes:

⭐ Explicit teacher lesson

⭐ Over 125 detailed teaching slides with interactive features

⭐ Student practice pages

⭐ Reading passage with comprehension questions

⭐ Dictation practice

⭐ Assessments

⭐ Home Connection page

Skills students develop:

• Morphological awareness

• Vocabulary development

• Decoding multisyllabic words

• Encoding and spelling accuracy

• Reading comprehension

• Word analysis

• Academic language

• Greek and Latin root knowledge

• Prefix and suffix application

• Structured word inquiry

Perfect for:

• Grades 3–5

• Structured Literacy classrooms

• Science of Reading instruction

• Orton-Gillingham informed instruction

• Small groups

• Whole-class spelling instruction

• Reading intervention

Spelling with Structure™ follows a carefully planned scope and sequence, allowing students to build new learning on previously taught concepts. Each lesson intentionally integrates phonics, orthography, morphology, and vocabulary instruction so students develop a deeper understanding of how English words work.

Why Teach Morphology?

Morphology is one of the most powerful ways to expand vocabulary and improve reading comprehension AND spelling! When students understand meaningful word parts, they can independently figure out the meanings of unfamiliar words across science, social studies, math, and literature.

Whether you’re teaching whole group, small group, or intervention, Unit 4 gives students the tools they need to confidently tackle increasingly complex words while strengthening both reading and spelling.
