Start with "Planting a Rainbow" to illustrate the planning and planting process. Colors are the highlight here, as the flowers in the flower garden all represent the colors of the rainbow. The process of growing from seeds and bulbs is also shown.
"Growing Vegetable Soup" is a great book to show the growth of vegetables from start to finish. Little ones are not always sure where their food is coming from, and may need the visuals to make connections between what they eat and how it come to be. Combine this with a trip to a local farm or farmer's market to get your child's brain thinking outside the supermarket.
"Eating the Alphabet" is another great book for seeing what different foods people eat, including some your child may not be familiar with. It relates each food to alphabet letters, both upper and lower-case, for authentic learning. When children can see and experience things that they read, it becomes more real and stays with them longer. Learning the alphabet this way will give them reference points - visuals - to connect to.
Lois Ehlert is the author of so many great learning books - "Color Zoo" teaches shapes and animal names, as well as giving children a view into how pictures can be broken down into shapes, for easier drawing :) Die-cut pages and surprise flipsides give every reader something to look forward to, as the pages turn.
In the fall, "Leaf Man" and "Red Leaf, Yellow Leaf" are wonderful tools for learning all about the changing of the leaves and the process that deciduous trees go through each cycle. The author' s creative use of natural materials to make pictures in "Leaf Man" will have you and your child seeing leaves in a whole new way! Try to make your own leaf creations when you're done :)
"Snowballs" is a crowd favorite for wintertime - something for every season! The use of natural, found items in her pictures is one of her style choices that delight young readers, as they find things on the page that are familiar.
Lois collaborated with other authors as well, illustrating the "Chicka Chicka" books, among others, so it's easy to see why her style is so familiar and attractive to little ones - and everyone!
Have fun reading!
