Product Description Product Specification Additional Information
 
Napier’s Bones is an ingenious math material that can multiply and divide very large numbers quickly and accurately. It is, in essence, a calculator. The set includes a series of ten wooden columns, 0 - 9. Below any given number, there are nine squares, each representing the multiples of that number. The tens and units of each multiple, each square are separated by a diagonal line. The strips will represent our multiplicand and the multiplier is along the left-hand side of the frame itself.


Our new set of Napier's Bones complete set are designed to provide a rich experience to your learners. It consists of a wooden Napier's Bones, a set of task cards, and a box for the task cards. Each card contains a control for errors on the back. The set consists of 76 cards divided into four sections with the following focuses:

Section 1 - Multiplication with One-digit Multiplier
Section 2 - Multiplication with Two-digit Multiplier
Section 3 - Division with One-digit Divisor
Section 4 - Division with Two-digit Divisor

We believe that scaffolded materials with control of error foster academic self-esteem and autonomy. We professionally design our materials with young learners in mind! This material is ideal for children ages 8-12 years.
