Simply Good and Beautiful Math 3 contains 120 lessons. The easy-to-use format instructs both you and your child what to say and do for each lesson. Blue text indicates instructions to you, the teacher, and black text is what you read to the child.

Daily lessons open with a short review section that can be skipped if your child has mastered the concepts. This course is divided into three units, each with a unit assessment. The Math 3 Answer Key is a free download found on the FAQs page.

Simply Good and Beautiful Math teaches through a spiral approach. Each lesson introduces a new concept, gives the child an opportunity to practice the concept, and then reviews previously learned material. Learn more about spiral math in the video below.
