A fantastic concertina book that serves as a height chart and a measuring tool to help curious kids get excited about mathematics and measuring. On one side it's a beautiful vintage-style height chart that can be hung on a wall. Flip it over, and it's an activity book that kids are invited to take around the house filling it in; what's bigger--your teddy or a box of cereal? Your mom or your bathtub? When folded, the book measures exactly one foot long, helping make the concept of length more digestible. Weight and volume are also explored. With bold pantone colors and immaculate slipcase packaging, this is both utilitarian design and practical math in action
