- Kid"s Box is a new, six-level course for young learners. Bursting with bright ideas to inspire both teachers and students, Kid"s Box gives children a confident start to learning English. It also fully covers the syllabus for the Cambridge Young Learners English (YLE) tests. The Alphabet Book is designed to help children, whose mother tongue is not based on the romanic alphabet, to recognise and practice the formation of all the letters in the alphabet. The language covered corresponds to Kid"s Box but this book can also be used with other corresponding courses.
