Napier's bones is a method that makes multiplying large numbers easy! This multiplication method was used for more than 300 years until the invention of mechanical calculators. The reason they were called Napier's Bone's, was because they were made out of bones. Multiplying large numbers may be a bit tricky for students. Napier's bones, also called Napier's rods, are numbered rods which can be used to perform multiplication of any number by a number 2-9. Age 7 to 11 Challenge Level Problem Getting Started Student Solutions The Scot, John Napier, invented these strips (originally made from bone) about 400 years ago to help calculate multiplication and division. This is what they looked like: Can you work out how to use Napier's bones to find the answer to 24 x 6? How about 461 x 4? Now try 8931 x 6. This is a calculator published by John Napier in 1617 If you study the set up you can see how it works. Three "bones" Cut out all the bones in vertical strips so you can make your own calculations Keep the frame to help you stay organized. Make a number with the "bones" across the top Find its multiples up to 9 using the chart

1 Featured By dave.vaness.79 Follow More by the author: John Napier was a late 16th/17th century, Scottish mathematician and inventor, although I consider him to be an Engineer. He was obsessed with simplifying mathematical calculating and his work led to him discovering logarithms. Napier's 'Bones' John Napier, from Scotland, invented a system of rods (originally made from animal bones, later from wood) marked with numbers that could be used to calculate large multiplications. What children will find interesting is that he reduced multiplication to addition. Explore Napier's Bones Make you own bones
