Interactive books, usually containing elements that the reader can alter or engage with. They are generally designed for (and marketed to) children.
An activity book is a type of book, generally aimed at children, which contains interactive content such as games, puzzles, quizzes, pictures to colour and other elements which involve writing or drawing in the book itself. The book may, or may not, have a loose narrative or contain other non-interactive elements structured around the interactive elements. Activity books may be made for entertainment, education or a mixture of both.
Specific types of activity book include colouring books and puzzle books. A book is normally referred to as an activity book if it combines a variety of interactive elements and does not fall neatly into one of these more specific categories.
