Reach for this book when you want to turn a quiet afternoon into a playful brain workout or when your child is starting to grapple with the dizzying concept of large numbers. It is the perfect choice for a child who finds joy in 'what if' scenarios and loves to see a simple premise taken to its most extreme, hilarious conclusion. Through the story of a girl who begins to spontaneously double, the book transforms abstract mathematics into a tangible, laugh-out-loud adventure. While the core of the story is an exploration of powers of two, the emotional heartbeat is the warmth of a family that remains calm and welcoming even as their house fills with Alisons. It is a brilliant tool for building early numeracy skills without ever feeling like a lesson. The whimsical illustrations and clever wordplay make it a delight for both preschoolers and early elementary students, proving that even the biggest problems can be managed with a sense of humor and a lot of extra chairs.
The book is entirely secular and lighthearted. While the idea of losing one's individuality or being 'replaced' by a double could be existential, the tone here is purely absurdist and safe. The resolution is whimsical and open-ended rather than heavy.
A first grader who is just beginning to understand multiplication or doubling and has a quirky, logical sense of humor. Also great for a child who feels a bit 'lost in the crowd' and will find the literal multiplication of a protagonist empowering and silly.
This is a fantastic 'read cold' book. Parents might want to brush up on their 'doubling' math (2, 4, 8, 16, 32, 64...) to help the child keep track of the numbers as they escalate. A parent might reach for this after hearing their child ask, 'What is the biggest number in the world?' or after a chaotic playdate where it felt like there were 'ten of them' running around.
Younger children (3 to 5) will enjoy the visual gag of seeing more and more Alisons on each page. Older children (6 to 8) will appreciate the actual math involved and the logistical absurdity of fitting sixty-four girls on a bus.
Unlike many concept books that feel like textbooks in disguise, Ahlberg and Ingman use a 'tall tale' format to make exponential growth feel like a slapstick comedy routine.
Alison Hubble wakes up one morning to find she has doubled. By the time she gets to school, there are four Alisons. The pattern continues exponentially: 8, 16, 32, and so on. The story follows the logistical and humorous challenges this poses for her parents, her teacher, and the community as they try to accommodate an ever-growing crowd of identical Alisons.
