Hello Goodbye

Sometimes the simplest ideas are the best. Taking twenty-one images and their reverse, Delphine Chedru has created a fun and engaging book for young children to learn the associations between words and their opposites.
Hello Goodbye wittily presents pairs of words such as light and heavy, night and day, and near and far in amusing illustrations that come to life, one word at a time, thanks to a red and blue filter that is very easy to use: the red filter makes the red illustration disappear and the blue appear, and vice versa. The interactive quality of the book catches children's attention and encourages them to make connections with words they are familiar with-all while keeping them entertained.
