Napier's bones are a visual tool for explaining the process of multiplication.
This simple tool can be used to clearly demonstrate how to multiply numbers.
If you are unfamiliar with how Napier's bones work, you can easily find out by searching online. There are numerous explanatory tutorials available.
The board is designed for five-digit numbers that are multiplied with one-digit numbers. To make full use of Napier's bones, I recommend printing the board and several “bones” for each number from 1 to 9. Maybe you need more than one “bone” for each number.
