Place value with whole numbers review

Let's continue our review of place value, now with whole numbers.

READ AND WRITE WHOLE NUMBERS:

1)  Circle the periods. A period is a set of three numbers usually separated by commas.
      for example in the number 345, 982, 615 there are three periods.  The digits 3, 4, and 5 make up the millions period, the digits 9,8, and 2 make up the thousands period and the ones period or units period is made up of the digits 6, 1 and 5.

2) Label the commas.  The first comma is "named" Thousand, the second is Million and the third is Billion

3) Start on the left (the largest place) and write the name of the first circled 1,2 or 3 digit number.
The period farthest to the left will not always have 3 digits.  Subsequent periods will always be made up of 3 digits

4) Now write down the name of the corresponding comma. (Don't forget to add a comma in written form)

5) Repeat the steps above for all other periods



FIND WHICH PLACE A DIGIT IS IN 

In which place is the 5 in the number 657,890?

1) Rewrite the number

2) Put a 1 under the number you are looking for In this case, you would put a 1 under the 5 digit.

3) Put zeros under all digits to the right of the 1  Here you would have zeros under the 7,8,9 and 0.
     you now have 4 zeros

4) Add the necessary commas.  you now have 10,000

5) The name of the number you have created is now the name of the place you are looking for.  In this case, the 5 is in the ten thousands place.

REMEMBER, when in doubt, label, label, label.  If you have labeled everything, you have something you can look back on if you get confused.  Most mistakes are due to a lack of attention to details.

Take your time, do good work and we'll see you on the bragger board!!
