The Counting Method for the Cranmer Abacus Debra Sewell & John Rose (2019)

The Cranmer Abacus is a mathematical tool used for addition, subtraction, multiplication, and division of whole numbers, decimals, and fractions. For the student with a visual impairment, the abacus is comparable to the sighted student’s pencil and paper and should be considered a fundamental component of math instruction. The Counting Method for the Cranmer Abacus (204 pp) emphasizes the understanding of place value, outlines the importance of this mathematical tool, and gives step-by-step instructions for completion of sample problems using the counting method.
