Sign in to write a reviewA 4 to 6-year-old who is curious about how things work, loves to build, and might be starting to engage in rudimentary engineering play with blocks or LEGOs. It's especially valuable for a child who experiences frustration when their ideas don't work immediately, as it normalizes the trial-and-error process in a very positive and funny way.
No preparation is needed. The book is simple, self-contained, and can be read cold. The concept is immediately understandable to young children. A parent has just seen their child get upset and give up after a block tower fell or a drawing didn't look right. The child exclaims, "I can't do it!" The parent is looking for a book that models perseverance and shows that making mistakes is part of the fun of creating something new.
A younger child (4-5) will primarily enjoy the slapstick humor of the bumpy rides and the clear visual difference between the wrong shapes and the right one. An older child (6-7), especially one beginning to read independently, will better appreciate the logical sequence of problem-solving. They can connect the Ogs' process to the scientific method of testing a hypothesis and learning from results.
Unlike many books about invention that are biographies or cover a range of inventions, this book's unique strength is its singular focus on one fundamental invention: the wheel. It deconstructs the creative process into its most basic, accessible steps for a very young audience. The use of pure slapstick humor to illustrate failed attempts makes the concept of perseverance exceptionally fun and non-preachy.
A prehistoric family, the Ogs, needs to move a large rock to their cave. They decide to invent something to help. Their first attempts at wheels are comically ineffective: a square one makes for a bumpy ride, a star-shaped one gets stuck, and a wiggly one is just silly. Through this process of trial and error, they observe what doesn't work and finally design and create a round wheel, which successfully helps them move the rock with ease. They celebrate their useful new invention.
