"Readers are invited to share their thought process — and sometimes whimsical ways — for tallying things up — as they explore colorful photos featuring mathematical groupings of everyday objects in How Did You Count? by two-time Mathical award-winner Christopher Danielson."―The Mathical Book Prize Committee"How Did You Count? is a gorgeous and inviting picture book for all ages."―Fawn Nguyen"Another gem from Christopher Danielson, with all his usual hallmarks: delightful and insightful, playful and profound, everything that math should be."―Eugenia Cheng, author of Is Math Real?"This work is important for anyone privileged enough to cross mathematical paths with thinking children. A perfect addition to his previous works, Danielson unpacks the act of counting in a manner that is inviting, immersive, thorough, and whimsical. How Did You Count? only strengthens my assertion that no one has deepened my appreciation for a child’s mathematical mind more than Christopher Danielson."―Nat Banting, Mathematics Teacher, 2019 Rosenthal Prize Winner, 2021 Prime Minister’s Award for Teaching Excellence in STEM"Christopher Danielson's How Did You Count? invites families, kids and teachers into math conversations about counting, number, structure, and strategy. Anyone familiar with Danielson's other work—How Many?, 21st Century Pattern Blocks, tiling turtles, etc.—will be delighted with How Did You Count? Anyone looking to get kids talking about math has an invaluable new resource at their disposal."―Dan Finkel"For a book of ostensibly simple pictures of groups of familiar objects, How Did You Count? is full of unexpected complexities. And by design; Danielson has carefully curated an exhibition of images of numbers of everyday things that invite different ways of counting at different degrees of sophistication. Perfect for in-class number discussions, and for sharing one-to-one."―Simon Gregg
