Math Update on Place Value

Posted: October 1, 2018

Currently we have been working on interchanging between standard form (forme symbolique), expanded form (forme dévéloppée), and written form (forme en lettres) with large numbers in the millions (millions), billions (milliards), and trillions (billions). 

**The French terminology is in brackets. 

If you would like to practice with your child at home, here is an example to help: 

Expanded Form (Forme Dévéloppée): 30 000 000 000 + 4 000 000 000 + 900 000 000 + 3 000 000 + 100 000 + 50 000 + 600 + 40 + 8

What is the standard form (forme symbolique) and written form (forme en lettres) of this number?? ^^

Answers:

Standard Form (Forme Symbolique): 34 903 150 648

Written Form (Forme en Lettres): thirty-four billion nine hundred three million one hundred fifty thousand six hundred forty-eight 

(trente-quatre milliards neuf cent trois millions cent cinquante mille six cent quarante-huit)

**Be sure to emphasize how the amount of zeroes in a number in expanded form helps to determine place value in standard form.
