Ladybird Readers is an ELT graded reader series for children aged 3-11, designed to help them learn English as a foreign or second language. The series includes traditional tales, popular characters, modern stories, and non-fiction, all beautifully illustrated and carefully written by language learning experts. With structured language progression, the series develops children's reading, writing, speaking, listening, and critical thinking skills across eight levels aligned with the CEFR. Language activities prepare children for Cambridge English Pre-A1 to A2 (YLE) tests, and each book includes a unique code for online audio and extra resources. "Is it Nat?" introduces phonics and sight words, with two versions of the story focusing on letter recognition and pronunciation.
