This book is part of a book series called Collins Big Cat .

. This book is part of a reading scheme, meaning that it is a book aimed at children who are learning to read. This reading book uses the phonics method. This approach concentrates on teaching children how to map between sounds and spellings, allowing them to decode written words into their constituent sounds. Phonics skill thus involves being able to split the written word 'cat' into the phonemes /k/, /a/, /t/, and to map from letter 'c' to phoneme /k/, from letter 'a' to phoneme /ae/ and from letter 't' to phoneme /t/. Decoding skill is useful when reading unfamiliar words which use regular spelling sequences.

There are 48 pages in this book. This book was published 2017 by HarperCollins Publishers .
