Similar to a traffic light, your engine can be green, yellow, or red. When you feel happy or calm, your engine is green. When your engine is green, your muscles feel relaxed, and your breathing is steady. Other times, when you're nervous or angry, your engine is yellow or red. When your engine is yellow, you might pick your fingernails or wiggle in your seat. When your engine is red, you might clench your fists and feel shaky.
Positopia World books feature Jack, who sometimes doesn't know how to control his engine. Disguised as wildly entertaining adventure stories, each Positopia book helps kids learn how to manage their emotions, and introduce exercises that parents, teachers and therapists can use to aid their children and students.
