Reading is one of the most powerful ways to take your Spanish from the classroom to the real world. But if you're at an intermediate B1 level, picking up an unadapted novel by a native author can be deeply discouraging. When you have to stop every sentence to look up a word, the pleasure of following a story quickly turns into a joyless slog, and many learners simply give up.
This is where graded readers come in. These are classic stories that have been carefully adapted for language learners. With vocabulary and grammar simplified to a specific CEFR level, they allow you to enjoy a great book, follow the plot, and absorb the language naturally—turning a chore back into a pleasure.

Frequently asked questions
What exactly is a graded reader?
A graded reader is a book, often a classic novel or a collection of short stories, that has been simplified for language learners. The vocabulary, grammar, and sentence structures are adapted to a specific proficiency level, such as B1, allowing you to read comfortably and enjoy the story without the frustration of a text that is too difficult.
Why is reading so important at the B1 level?
At the B1 intermediate level, you have a good grasp of the basics. Reading extensively is the best way to build on that foundation. It exposes you to vocabulary and grammar in context, helps you develop a more natural feel for the language, and massively increases your word recognition, moving you towards true fluency.
What makes Pentecost graded readers the best choice for self-study?
Our readers are designed as a complete learning system. The key advantage is the Spanish-to-English glossary in the margin of every page, so you can check a word's meaning instantly without losing your reading flow. This is combined with a science-based vocabulary selection, a unique in-book difficulty progression, chapter exercises, and printable flashcards to create the most effective and supportive reading experience for independent learners.
How do I know if a B1 book is the right level for me?
A good guideline is the 'five-finger rule': open a page at random and count the words you don't know. If there are more than five, the book is likely too difficult. Our books help solve this with their built-in progression, starting easier and growing with you, and the margin glossary provides a safety net for any challenging words.
Should I look up every single word I don't understand?
No, the goal of extensive reading is to read for flow and general understanding. Try to guess the meaning from context first. If a word is preventing you from understanding a key part of the story, that's the time to look it up. Our margin glossary makes this process quick and painless, so it doesn't feel like a chore.
