• ​If we multiply this number, what is happening to the value?

• ​When the value gets larger, which direction are we shifting the digits?

• ​Multiply thirty-six hundredths by 10 --> what is the product?

• ​Multiply thirty-six hundredths by 100 --> what is the product?

• ​Multiply thirty-six hundredths by 1,000 --> what is the product?

​Dividing Decimals by 10, 100, and 1,000

• ​Write two thousand four hundred twenty-seven on your place value chart

• ​If we divide this number, what is happening to the value?
