Rhyming is a foundational literacy skill. Through simple, engaging text, our Rhyming Word Families series introduces common letter groupings and repeats them throughout a silly story. This repetition allows beginning readers to identify rhyming patterns and start to read on their own. Outstanding original artwork, an introduction to the author and illustrator, and a word list for review all further aid new readers' comprehension. A frog requires the help of a dog to find a favorite log in a dense fog. This simple story for beginning readers teaches the "og" sound through rhyming text and bright, original illustrations. Additional features to aid in comprehension include a word list for review, a note to parents and educators, and an introduction to the author and illustrator.
