Commas help us identify the periods in larger numbers. Think of reading large numbers in "threes". Watch this video to help you explore how to read large numbers using the commas.

We're going to use commas to help us identify the periods and numerals as we both read and write these numerals in word form reading them will help us

write them. So take a look at our Millions period and then you have that comma our thousands period with the comma and then our units period comes at the end and

reading it we look at two million and then we group these three digits together and say

And then we group these three digits together and say 682 so all together it would be two million four hundred fifteen thousand six hundred

eighty two now in order to write that we're going to take those numerals and we're going to write them out so that they

are similar in what we sound like as we're reading them. So we're going to start with the Millions period and start with two Two and then write out

the comma four million. So we have two million and then we're going to take a look at the thousands period and write these

three digits as one number. So it would be 415 thousand.

And we're going to take and make sure that we spell out that word thousand and then add the comment in so we have our thousand period and then we're going to take a look

at our unit period at the very end and spell out 600.

don't forget to put that - in between the 82. So if we're reading it with our word form, we read two million, four hundred fifteen

Try another number. 6,204,711 Remember to start reading the number by saying six million. Then read the next three digits as two hundred four. Then say the comma name of thousand.&nbsp;So it would read, two hundred four thousand. Then finish the number by&nbsp;reading the digits 7-1-1 as seven hundred eleven. When you put it all together it sounds like… six million, two hundred four thousand, seven hundred eleven
