Building Skills Through Targeted Exercises
Student Books
Exercises offer targeted practice in reading and spelling at the syllable, combined-syllable, and whole-word levels. Students engage in activities such as matching words with definitions and using words in various contexts. Each lesson concludes with brief content-area passages, allowing students to apply lesson words in connected text, building both comprehension and fluency.
Exercises in student books feature:
- Practice with both decoding and encoding
- Practice in both structural and morphemic analysis to support accurate, automatic word recognition and vocabulary development
- Fluency practice and comprehension tasks using content-area text to develop higher-order thinking and strategies
Lesson Structure

Targeted Word Lists
Each lesson begins with a comprehensive list of words that focus on the target pattern(s) and common phonics or structural elements of the English language.

Six-Step Lessons
Build skills progressively, starting with one-syllable words and advancing to applying them in context, while monitoring accuracy, fluency, and proficiency.

Writing Practice
Students have opportunities to incorporate newly learned words into their writing.
Focused Insights to Guide Student Progress
Assessment
The Megawords Assessment of Decoding and Encoding Skills is a test designed to evaluate reading and spelling skills. It helps teachers identify which skills students have mastered and which need further practice. The results guide teachers in placing students into the right Megawords level and word list for their learning needs.
- Evaluates decoding and spelling skills
- Identifies mastered skills and areas for improvement
- Helps identify specific reading intervention needs
Guided Placement
Teachers use results from the initial assessment to place students in the appropriate Megawords level and word list.
