Serial Picture Book Project Wrong! Wrong! Wrong! 

Project Overview

Young children start to distinguish impossible events (for example, flying tables, talking bread, or apples made of apple jam) from daily life before four years of age. In their childhood, they continue to find events amusing and entertaining that violate daily norms or common sense. To stimulate such joy, there are games, pictures, and nursery rhymes in which deliberate mistakes are made to amuse children and others in which children are tasked to find the mistakes.

Our project Wrong! Wrong! Wrong! aims to stimulate the joy of finding pre-set mistakes in picture books. Our books target 3–6 years old and will present large scenes with one or more mistakes hiding within, with or without a storyline, and ask young readers to search and find.

Here is one example of a scene with one “mistake” in it: On a beach in the summer, people are having fun playing with water, building sandcastles, playing beach volleyball, etc. However, one thing is not right: As the sun is hanging over the right edge, all the shadows are on the left, but the shadow of one basket is on the right.

What This Project Brings to Young Readers

Visual abundance: As children grow, they are willing and prepared to appreciate more complex visual stimuli. Detailed illustrations will attract their attention and encourage them to discover.

Observation training: The task demands young readers focus on every detail they meet. Instead of merely looking at it, young readers must reflect on what they observe at a conceptual level to tell what’s right and wrong.

Knowledge enrichment: To understand what’s wrong, one must know what’s right. The serial books raise questions on what has been accepted as everyday knowledge and help young readers transfer implicit knowledge into explicit knowledge.

Also, please note that these benefits are all self-motivated. The serial books only exhibit objective scenes rather than telling children what to learn. This empowers young readers to find, comprehend, and develop on their own.

Target Audience:

This project is intended for both the Chinese and American markets. Our project will be the first original picture book series to cover the “search and find what’s wrong” area in mainland China.

Our target readers are children aged between 3 and 6 years old. During this period, children become very curious about the world and are open to challenging tasks. Nevertheless, we still hope children aged between 7 and 12 years old will also enjoy our books. We hope parents can also appreciate the books’ tasks, and we aim to provide a situation where children and parents can read (or compete) together.

Suggested Content:

  1. Each book should be able to be read individually, independent of the publishing order.
  2. The main task in the serial books will be finding one or more pre-set mistakes on each page. We value mistakes at conceptual levels more than perceptual ones. For example, fishing in a pool instead of a lake is better than having a horse grow five legs. Also, we value the quality of the mistakes over how many mistakes can be put onto a single page.
  3. Each book will have a topic that organizes all the scenes in it. The topics could be:
  • Domains of knowledge that the mistakes violate, such as daily routine (day and night, home and kindergarten), artifact knowledge (computers, vehicles), natural rules (seasons, gravity, animals), etc.
  • Different kinds of mistakes, such as wrong mental states (a troop of firemen calling for firemen), wrong category (lion eats grass), violation of the essence of an object (brick that floats), etc.
  • Different countries, life scenes, or landmarks that the main characters visit, with local cultures or features that attract young readers.
  1. We welcome sub-topics that add flavor to the books. The sub-topics could be:
  • Hidden characters that keep appearing on each page. After finding the mistakes, young readers can still enjoy finding these additional sub-topics.
  • Other cognitive tasks, such as mazes, pattern-finding, memory challenges, counting, etc.
  • False alarms that look like mistakes but are actually not, such as improbable but not impossible events, local cultural objects, magic shows, modern technology, etc.
  • Other interesting features.
  1. The artwork briefs should be submitted together with the text. 

Product details:

  • Page count: 12 spread (24 pages) expected; adjustments can be made accordingly.
  • Book size: 8.5×11 inches or larger.

Serial Picture Book Project Second in the World

Project Overview

For far too long, we have given too much attention on the stories about the “world’s first” achievements—for example, the first human to sail around the world, to step on the Moon, to prove a mathematical theorem, to fly an airplane, and stories about the highest mountain and the longest river in the world. But the stories of the world’s seconds are still worth telling. The Second in the World series aims to tell these non-fiction stories to young readers in both America and China, stories about achievements of the human race, of which the firsts are known worldwide, but the seconds are rarely acknowledged.

What Does This Project Bring To Young Readers?

Historical education: Through thousands of years of civilization, human beings have achieved many things that changed the world—things that are still widely known and remembered by readers nowadays. This book series goes a step further. The Second in the World series aims to tell real, historical stories about splendid human achievements, which are rarely known because they were not the first pioneers.

Challenging spirit: We are looking for inspiring stories/character protagonists that encourage people to make a difference in their lives and the world.

Reading for fun: We would like to present young readers with fun facts about history/science/human achievements that other books haven’t told.

Target readers: 

We aim to entertain young readers between 3– 6 years old who are beginning to show an interest in world history and knowledge. 

Suggested Content:

  1. Each book in this series should be able to be read on its own, separate from the series, regardless of the publishing order.
  2. Each book should take the form of a non-fiction picture book for children aged 5–10.
  3. The stories should concentrate on a person or a group of people, animals, or plants that have a second place in a widely-known achievement/record.
  4. The achievement/records themselves should be widely known or easily understood by children aged 5–10 years old. We also expect them to be about world-changing discoveries.
  5. The first place person or achievement should be widely known, and the second should be rarely known. For example, Dolly the sheep was the first cloned animal in the world. In contrast, the second cloned animal is rarely known.
  6. The story should be unbiased, especially when it concerns controversial people or topics. The story should also depict real, historical facts, especially when there are debates over “who was the first and who was the second.”
  7. The author is responsible for the work’s originality. All works that the author quotes or consults should be correctly cited in the text, the back cover, or the side bar.

Product details:

  • Page count: 32 pages, adjustments can be made according to the final work
  • Book size: 8.5 x 11 inches or larger
