Ages 6-8 | Chapter Book | Mysteries to Solve | PLUS Activities and Tips

Young Explorers is the Timmi Tobbson "early reader" series for adventurers and sleuths aged 6-8. In this series' first title, a secret message in an ancient book sends Timmi and his friends - including a three-legged frog - on a wild ride to unravel a life-changing mystery and become the Young Explorers.

In typical Timmi Tobbson fashion, each Young Explorers book offers solve-them-yourself picture mysteries, but that's not all. Accompanying the story is additional content aimed at sparking interest in technology, history and science in general.

Mysteries to Solve

Your child is the detective, and it's up to them to find and interpret clues. Each Timmi Tobbson Young Explorers adventure is divided into short chapters that end with a puzzle to be solved. Clues to the mystery are concealed both within the story and in the colorful illustrations, allowing children to combine information from different sources (text and illustrations) and make logical deductions. This hand-on approach trains kids' problem-solving capabilities and adds a certain level of immersion to the reading experience.

Facts for Explorers

After the story is completed, the book dives deeper into some of the themes shown in the story. Want to know more about ancient riddles, sunken treasure, or the role of secret passageways throughout history? The "Facts for Explorers" section investigates the real-life facts behind the purely fictitious elements of Timmi's story. "Facts for Explorers" aims to spark a little bit of interest in topics like technology, history, and science in general, encouraging kids to be more curious in their everyday lives.

Activities and Tips for Adventurers and Detectives

The third section of the book offers creative tips and tricks. How can you build a device that can turn saltwater into drinking water with just household appliances? How can you collect fingerprints with baking soda? How can you develop your own code to write secret messages? These pages motivate kids to experiment, explore, create, and build.

A Story for the Heart - A Challenge to the Mind

Staying true to the Timmi Tobbson brand, this is a story about friendship and about the drive to explore, to inquire, and to second-guess. Kids will enjoy watching as all three main characters show perseverance and courage in reaching their goal, and rely on the strength of true friendship to unravel each mystery.
