My girls (ages 3 and 6) love Team Umizoomi and we have a ton of the episodes on our DVR. They are always requesting the show. The show is great for its vivid colors and fun songs. The shows and the books always have a positive message and teach kids about math, counting, shapes, patterns and teamwork. They are very educational.
The book is about the group playing with a dog named Buster who get lost and the team must work together to rescue him. This book is a very simple reader. I would say it is on the easy end of the level 1 readers out there and would be great for your a young child that is just starting to read. The words are very simple and primarily consist of basic sight words which will build your child's confidence in reading. The art is great and it includes some stickers. It will not be of much interest to anyone over the age of 5.
We have several great Team Umizoomi books in our collection of readers and bedtime books and this one is no exception. This is a highly recommended addition to you child's collection of early readers.
