Working with Whole Numbers & Identifying Number Patterns

We have been practicing naming whole numbers represented in standard form, words, expanded form as well as identifying the value of individual digits within larger numbers. 

For example:

Standard Form: 14,908 
Words: fourteen thousand, nine hundred, eight
Expanded Form: 10,000 + 4000 + 900 + 8

We have also been practicing converting numbers from one form to another.

For example:
one hundred eight thousand, seven hundred fifty four (number words) = 108,754 (standard form)

There is a place value chart posted in the classroom for students to refer to. They must remember that digits in larger numbers are grouped into houses and each house has space for only 3 digits! When representing numbers in words or standard form, the houses must be separated by commas. I always tell them to leave a little space between houses as well. When representing numbers in expanded form, the different values are separated by a plus sign.

We have started to talk about patterns, in particular number patterns. We are a applying our knowledge of place value to identify number patterns, pattern rules and to create our own number patterns. These two areas will continue to be a focus in math class!
