My son is 11 is and thinks Nitter Critter is awesome. He enjoys the humorous touch that is added to what can be a dry, boring subject. My seven year old daughter loves reading Nitter Critter's lines as she and Mrs. Dunbar go though the lessons. He really captures a child's outlook and thoughts and brings the lessons to life.
My 7 year old son loves Nitter Critter and has amazed me with his progress in just 1 year. The character is engaging and my son is eager to practice and improve.
