At this point, we are doing some review work in Number Sense using the Place Value chart. Even though we are dealing with numbers, there is still the element of measurement. If we could quantify some of the examples below, it might help with our understanding. since we are comparing values. We have used the Base 10 blocks to assist us with understanding that the following items represent certain things:
Unfortunately, I do not have enough Base 10 "1.0" in the classroom to represent $10, $100, or $1000. I can offer a couple of examples of the pattern behind the values increasing:
This image, paying attention to the numbers in the middle, demonstrates what happens when we multiply the term by 10. Simply, we are adding a zero, to the digit. I believe the list of numbers on the far left corresponds to the exponent value.
The other example continues our example of money, but the values are being multiplied by 10, but 100.
For the more musically inclined, check this one. It will review some of the concepts we have learned: Standard Form, Expanded form and in words. There are countless videos on YouTube and I could upload videos upon videos, but that would be overwhelming. Spend some time, on your own, checking out the great things available on YouTube to help supplement some of the things we do in class.
