This adorable classic by known author and illustrator Maurice Sendak of 
Where the Wild Things Are fame includes a simple poem for each month of the year. In addition to being a super cute story, 
Chicken Soup with Rice
 also has a song that goes along with it. Children who learn best 
through music may benefit from this added element of this picture book 
for teaching the months of the year. Just search online for the 
Chicken Soup with Rice song if you would like to add it to this cute book. An excellent read-aloud, demonstrating the progression of the year, seasons,   and the power of poetry. And of course . . .

Here are some other books for the months of the year - 
Here Comes the Year by Eileen Spinelli. This picture book for 
learning the months of the year is more complex than most. The lyrical, 
rhyming words for each month use descriptive adjectives and verbs to 
describe each month as it relates to nature. Because of the rhyming 
words this book is a great read-aloud choice for teaching the months of 
the year. This book, however, is best for older children that already 
have a somewhat established idea of months. The wording is too difficult
 for very young learners.
The Turning of the Year by Bill Martin Jr. Teachers, parents, and
 just about anyone who knows the first thing about children's books, 
knows Bill Martin Jr. as the author of the wonderful 
Brown Bear, Brown Bear
 picture book series. Martin delivers again with this great book for 
teaching the months of the year. Cute poems on each page give insight 
into what each month holds. The illustrations are lovely (though not 
done by Eric Carle a la 
Brown Bear, Brown Bear) and add to this great picture book for teaching the months of the year.
