The poem "The Eleven" by Archibald MacLeish does not explicitly mention any shapes that the child sees. The poem is a free verse exploration of a child's perception of the world and their inner thoughts, focusing on the child's experience of counting and their relationship with the number eleven.
The focus of the poem is on the child's sensory experience and the abstract way their mind works, rather than on specific shapes. The poem doesn't describe what the child is seeing, but rather how they are processing the world around them.
