The BIG FAT NOTEBOOK (TM) series is built on a simple and irresistible conceit-borrowing the notes from the smartest kid in class. There are five books in all, and each is the only one book you need for each main subject for ages 9-14: Maths, Science, Coding, English, and World History. Inside the reader will find every subject's key concepts, easily digested and summarized: Critical ideas highlighted in marker colours. Definitions explained. Doodles that illuminate tricky concepts. Mnemonics for a memorable shortcut. And quizzes to recap it all.
