The Frog Series is a set of 8 decodable books for students in first grade. There are 4 fiction titles and 4 non-fiction (NF) titles. Each book was written to be decodable, comprehensible and engaging for our youngest readers. Stories are meant to be read in a single sitting (25-30 pages in length), and the skills increase in complexity with each book. All of the books in the Frog Series have comprehension questions, a writing prompt, and are 9x9 inches with a soft cover and durable thread-sewn binding.
