The Meaning and Orgin of Numbers You have to admire the intelligence of a person who created something so simple and perfect that it has lasted for thousands and thousands of years and probably will never change. The numbers we write are made up of algorithms, (1, 2, 3, 4, etc) called arabic algorithms, to distinguish them from the roman algorithms (I; II; III; IV; etc.). The arabs popularised these algorithms, but their origin goes back to the phenecian merchants that used them to count and do their commercial contability. But how did they come up with the idea that a 1,2,3,4 etc would look the way they did - the explanation is very simple and brilliant - the way they are written is because of the angles contained in each number.

​ Excellent for teaching reflection!




 * = **__Subitize, Subitize__**

Subitize, Subitize Seeing sets of different size Sets of 3, sets of 5 It's lots of fun to subitize!

Sets of 4 and sets of 2, Let me subitize with you. Sets of 6 and sets of 4, Let us subitize some more!

Subitize, subitize, Seeing sets of different size!

5 pennies trade a nickel 2 nickels trade a dime 2 dimes and a nickel trade a quarter every time! 4 quarters trade a dollar And that is quite a lot And a dollar in my poket is exactly what I've got!

by: Linda Wilson ||  ||= **__The Money-Value Song__** (Tune: Farmer in the Dell)

A penny is one cent! A nickel is five! A dime is ten pennies, And a quarter is twenty-five!

A dollar is one-hundred Pennies in a row, Now with this little sone, Money-value I know!
