Octopuses Have Zero Bones deftly achieves two different goals. Its beautifully illustrated pages both describe our system of numerals and apply them to the universe around us, far and near. The young reader simultaneously acquires a sense of the scale of things and a language to describe it. Kids will be wowed by the pictures and linger over the examples—and maybe even measure a few new items for themselves. This is a multi-dimensional triumph.
