Week of August 21
This week we began working on multiplying and dividing whole numbers by a power of ten. Our number system is in BASE 10, which means every place value is a multiple of 10. 10 ones make 1 ten, 10 tens makes 1 hundred, 10 hundreds makes 1 one thousand...etc.
As students multiply and divide by a power of ten, they begin to understand place value.
For background, please watch this Khan Academy video.
This video also illustrates powers of ten.
