Description Lorna is starting school today. She feels very nervous. Lorna finds it hard at first. But with the help of her basketball skills and her new friend, Lorna soon begins to fit in. The phonemes /ar/or/ are featured in this title. In Level 4 - Blue books, children build on the letter-sound combinations learned in levels 1 and 2. They learn consonant digraphs (sounds made up of two letters together such as 'ch' or "ll") and long vowel sounds (such as 'igh' or 'ai').
