Book Description
This easy-to-follow introduction to computer science reveals how familiar stories like Hansel and Gretel, Sherlock Holmes, and Harry Potter illustrate the concepts and everyday relevance of computing. Picture a computer scientist, staring at a screen and clicking away frantically on a keyboard, hacking into a system, or perhaps developing an app. Now delete that picture. In Once Upon an Algorithm, Martin Erwig explains computation as something that takes place beyond electronic computers, and computer science as the study of systematic problem solving. Erwig points out that many daily activities involve problem solving. Getting up in the morning, for example: You get up, take a shower, get dressed, eat breakfast. This simple daily routine solves a recurring problem through a series of well-defined steps. In computer science, such a routine is called an algorithm. Erwig illustrates a series of concepts in computing with examples from daily life and familiar stories. Hansel and Gretel, for example, execute an algorithm to get home from the forest. The movie Groundhog Day illustrates the problem of unsolvability; Sherlock Holmes manipulates data structures when solving a crime; the magic in Harry Potter’s world is understood through types and abstraction; and Indiana Jones demonstrates the complexity of searching. Along the way, Erwig also discusses representations and different ways to organize data; “intractable” problems; language, syntax, and ambiguity; control structures, loops, and the halting problem; different forms of recursion; and rules for finding errors in algorithms. This engaging book explains computation accessibly and shows its relevance to daily life. Something to think about next time we execute the algorithm of getting up in the morning.

Book Description
The first Grimm tale illustrated by 1998 Caldecott medalist Paul O. Zelinsky is once again available in hardcover. Originally published in 1984, Zelinsky's paintings for Hansel and Gretel are as compelling as his later work and will captivate readers with their mysterious beauty, emotional power, and brilliant originality. Each spread brings to life a world as rich and real as our own—detailed, colorful, sensual—yet filled with the unearthly shadowed magic of the Hansel and Gretel folktale. Whether portraying the fear and anguish of children abandoned by their parents, the delicious sumptuousness of a candy house, or the joy of being reunited with one's family, the artist captures the subtle nuances of emotion and the tactile quality of the physical world with exquisite accuracy and elegance.The hauntingly spare retelling of this perennial favorite by the poet Rika Lesser perfectly complements the vivid storytelling of Zelinsky's artwork. Once again this gifted artist gives us a unique interpretation of a beloved fairy tale, allowing us to both see it anew and rediscover its eternal truths.

Once upon a time, there was a misty blue mountain. Below the misty blue mountain was a wild, dark forest and by the wild, dark forest was a village.The village had a stream and a duck pond and an old red apple tree and it was home to Hansel, Gretel and their fairytale friends. The Fairytale Friends series brings fairytales into the modern day and features scenarios young children can relate to and learn from. Each story in this new picture book series focuses on a different fairytale character, a different strength or core virtue and a challenge to overcome, often with the help of their friends. Readers will enjoy spotting characters from other books and recognizing key elements of the original fairytale while enjoying the new twist. Notes and questions at the back of the book will summarize what the character has learnt and prompt further discussion while activities will provide more fairytale fun.

Book Description
Pity poor Streptococcus - it should be a piece of cake for a fairy godmother to tell the story of Snow White but her wand is bent and things aren't going quite as they should. Then, to make things worse, she's interrupted by a couple of English policemen who are hot on the trail of two very devious and dangerous criminals - children who are causing no end of trouble in the forest. Their names? Hansel and Gretel! Streptococcus doesn't believe a word of it and neither do a well-behaved pair of kiddies in the audience who volunteer to help her tell Hansel and Gretel's familiar tale. But before everyone lives happily ever after, the police insist on having their say and the well-behaved kiddies aren't happy about that at all... Since there are lots of parts (10 for girls, 5 for boys, and 10 for either), everyone gets a role and since a single forest set is all that's needed for this 60 minute show, it's easy to produce. This is a great fun twist on the familiar, favorite tale.
