Buku, the cheerful robot, takes his friends on a magical adventure to a faraway planet to help them discover what rules are, how they're made, and how good rules and manners keep everyone safe and fair.

"Why do we need so many rules?" Oli and Samu complain about rules all the time. Malena, who knows rules matter, sighs and wishes their friend Buku, the magical robot, could come and help them.

Buku, who hears everything, comes to the rescue. With a flash and a whirr, he takes the children on a spectacular journey. Gliding through the stars, they land on the Curious Planet of Rules. There, they meet the Giant-Heads and the Pin-Heads, explore their strange lands, and their peculiar views on rules.

As they hike across this funny and extraordinary planet, Malena, Oli, and Samu begin to see how rules and manners shape safety and fairness and they learn:

• what rules are and why we have them at home, at school, and in the community

• how fair rules help keep everyone safe, respected, and included

• that rules are not perfect and can be questioned and improved

• that creating useful rules is not easy -- we need to listen to each other, discuss and defend our ideas, and be able to come to an agreement with others.


With funny moments, thought-provoking ideas, and bright illustrations, The Curious Planet of Rules turns big questions about rules into a magical story kids will enjoy and talk about.

Perfect for:

• Kids ages 6-9 who constantly ask "Why do we need this rule?"

• Early independent readers who are ready for more developed picture book stories and enjoy reading alone or with an adult

• Families who want to talk about house rules, fairness, safety, and responsibility

• Grades 1-3 classroom and library read-alouds about rules and social skills

• The first days of school when teachers and students talk about class rules and expectations.

• Social-emotional learning around self-control, respect, empathy, and making good choices
