"Tilly in a Tangle" follows Tilly, who tries hard to maintain her boat and please her friends by following their advice, only to discover that her own methods are more effective when a crisis occurs. Activities for the book include a "Follow the Directions Game" where children discern between sensible and silly instructions, a "Sensible vs. Silly Sorting" activity to categorize advice, and a calming "Find Your Calm" guided meditation to teach children how to relax and unwind. These activities are designed to enhance understanding of the book's themes, encourage critical thinking, and promote mindfulness in young learners.
