Leap-frogging "over" a fire hydrant, ducking "under" "London Bridge," crawling "through" a pipe tunnel -- Tana Hoban's brilliant photographs of children transform these activities into a fascinating exploration of spatial concepts. There are twelve concepts in all -- and some surprising discoveries for the young child. As in "Look Again!" and "Count and See," Tana Hoban has created an imaginative and provocative adventure into the many ways of seeing.
