William Murray was an educational adviser at a borstal and later headmaster of a "school for the educationally subnormal" in Cheltenham. From research undertaken in the 1950s by Murray with Professor Joe McNally, an educational psychologist at Manchester University, Murray realised that only 12 words account for ¼, 100 words account for ½, and 300 words account for ¾ of the words used in normal speaking, reading and writing in the English language.
He developed 'The Key Words Reading Scheme,' a series of 36 English language early readers children's books, published by the British publishing company, Ladybird Books.
Starting with book 1a, a budding reader of primary school age, from 3 to 5 year old, is introduced to brother and sister Peter and Jane, their dog Pat, their Mummy and Daddy, and their home, toys, playground, the beach, shops, buses and trains, and so on. (wiki)
This book is basically a Ladybird Books story book that’s designed to help kids to learn to read. The story was so-so, but the execution was pretty good for what it was.
