Book Sets 1-4

These four sets (46 total books)

are the perfect supplement to any phonics-based reading curriculum.

Each book contains carefully chosen vocabulary, focusing on specific    phonics skills. These decodable books are incremental, beginning with short

/ă/ CVC words. Each book gets progressively more difficult, adding

new phonics skills in a systematic and sequential order.

Students love reading these books all

by themselves. This early success

builds confidence and students

discover that reading is fun.


Reading Reset 


Reading Reset was written for older students because we know that many students who enter middle school are not yet ready to read grade-level material.

This workbook is appropriate for classroom use with students who were never taught decoding skills or with students who need to develop strategies for building their vocabulary.

This workbook is also appropriate for small group use with students who are reading below grade-level and need to improve their foundational reading skills.

"Today is the perfect time for me 

to become the reader I know I can be."

About Us

Guth Learning materials teach students the skills they need so they can explore their unique passions on their own. We cultivate a love of learning.

“Reading is important, because if you can read,

you can learn anything about everything

 and everything about anything.”

   - Tomie dePaola

Cathy Guth has taught hundreds of students how to read, but all of the Guth Learning materials were written because Cathy’s real passion has always been to help students want to read. 

No one likes to do things they don’t understand, so Cathy knew that the first step in fostering the desire to read and the desire to learn was to teach students how to comprehend.

When you understand what you read, reading is fun.

“Cathy Guth’s Reading Comprehension series is user-friendly to both students and teachers.  

Teachers value the fast-paced lessons that require little preparation and focus instruction on essential grammar and reading comprehension skills.  

Students benefit from the practice and repetition, which allow them to become active thinkers as they read.”

Angela C.
Middle School Teacher

“The ACT workbooks by Cathy Guth are a perfect blend of strategy and content. While using the ACT Prep workbooks to teach a class, we would periodically look at a random ACT practice test to see if what the author said was really true. Every time, the author was spot on. Every time!

I truly believe that regardless of your ACT starting point, the strategies alone will help you increase your ACT test score.”
