Up to My Knees! (Storytelling Math series)

Reach for this book when your toddler is starting to notice how much they are growing or when they seem frustrated that they cannot yet reach things on high shelves. This story uses the natural world to validate a child's sense of self and their place in the physical environment. It is a perfect tool for parents who want to introduce early mathematical concepts through the lens of bodily autonomy and physical awareness. The story follows a young girl as she plants a sunflower and watches it grow. As the plant gets taller, she uses her own body as a measuring stick, comparing the flower to her knees, her waist, and eventually the top of her head. It is a gentle, rhythmic exploration of patience and the joy of seeing hard work bloom. Grace Lin's vibrant illustrations make the abstract concept of measurement tangible and exciting for children aged 0 to 3.
