Multiplying and Dividing Decimals Using Powers of Ten
Multiplying and Dividing Decimals by Powers of Ten

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.
