The Verbal Math Lesson Book 1: Step-by-Step Math Without Pencil or Paper / Michael Levin MD, Charan Langton MS

Everyone thinks kids hate math. But the truth is, kids don’t hate math—they hate worksheets! Writing down equations takes fine motor skills that young children haven't yet developed, making the process of learning math difficult and tedious. Math done mentally, or verbal math, makes math fun. Children see math problems as a game and a challenge. In the second edition of this pioneering educational bestseller, handwriting is removed from math problems to help children cement fundamental mathematical skills so that they may solve problems without having to do any writing at all. Developed as a supplement to traditional math education, the lesson is completely comprehensive, step-by-step, and leaves no area undone.

The first book of the series introduces children to the basic concept of adding and subtracting, and works its way up to math problems involving numbers with double digits. The book is meant for children between the ages of 5 and 7.
