Frog and Toad Are Friends by Arnold Lobel
The first book in a series of beginning chapter books about two best friends, Frog and Toad. The books are divided into five short stories that each relate an adventure of Frog and Toad’s and include simple but charming illustrations. Frog is optimistic while Toad is usually grumpy, but the two friends complement each other well and are always supportive of each other. The stories are touching and funny and emphasize the values of friendship and loyalty.
