High Frequency READERS 18 Books + Flashcards + CD (Original Price: 6,400 yen) Used for English conversation learning when my child was young. Now in elementary school, English is a strong subject. There are no markings, but there are some wrinkles from page turning. I think it will not hinder use. (The following is a reprint from the manufacturer's website) Words that appear frequently in English sentences are called "High Frequency Words." By memorizing them in advance, you can read without consciously thinking, which helps with reading in the initial stages. This is an 18-book series composed of simple sentences that repeatedly use "High Frequency Words," focusing on 21 words. • Each book uses illustrations and dynamic, beautiful photographs, so children can enjoy them without getting bored. • The included CD contains three different types of readings for each title.
