Improve Reading Comprehension Naturally by Deciphering Animal Ecology with Easy-to-Read Text!

The "Yuruyuru Zukan Reading Comprehension Workbook" series continues to gain fans among parents and children, based on the idea that "kids will proactively study things they love." The latest volumes are two books: one on astonishing "Extinct Animals" that once existed on Earth, and another on "Amphibians & Reptiles" known for their unique and fascinating ecology.

"Extinct Animals" focuses on texts about creatures that can no longer be seen, from trilobites that went extinct hundreds of millions of years ago to the Japanese wolf that lived until relatively recently. It also features many endangered species, providing an opportunity to think about our relationship with living creatures.

"Amphibians & Reptiles" explores the ecology of animals that have become popular as pets in recent years, such as colorful poison dart frogs and the uniquely looking frilled lizard.

Based on the "Yuruyuru Zukan" series, which has sold over 1 million copies, this series features newly written text for early elementary school students, making it perfect for first graders' very first reading comprehension practice.

Stimulate the Desire to Learn! "Shiny Stickers & Poster"

As a special bonus at the beginning of the book, there are 20 shiny stickers featuring the creatures from the book and a poster. By placing a shiny sticker on the poster after solving each story, children can proceed with their learning systematically and happily every day. With this workbook, you can draw out the child's desire to "complete the poster with shiny stickers!" and "solve more problems!", ensuring that often-stalled home studying becomes a fulfilling experience.

*The 21st story is a special edition, so there is no sticker for it.
