Each page of this place value anchor chart has a different period on it, labeled and color-coordinated. Cut them out and find a spot for them at the top of a whiteboard so that you can write numbers underneath each "place" on-the-go!
I've included billions through decimals, which I have found covers just about all the numbers than come up in math problems in my 5th grade class. The only time we go above billions is when we're discussing the solar system/galaxy/universe in science, and I added in the extra places with my dry erase marker. I've found that we occasionally have problems that use ten thousandths, which is why I've included the "more decimals" period.
This interactive anchor chart could be used in primary elementary grades when first learning place value or in intermediate grades for students that still struggle with "place value fluency."
