This week we're SUPER excited to learn about the SUPER Power of Ten! Using exponents is an efficient way to write numbers that have a few too many zeeeeeros.
The exponent (or power) tells us how many zeros are in the number when the base number is 10.
The image below has a place for everything with everything in its place. The base can be any whole number, but today we are only focusing on the POWERS of TEN!
Here are the vocabulary words for this lesson:
powers of ten
base number
exponent
Multiplying and dividing using Powers of 10 is SUPER fun!
When multiplying a decimal number by a power of ten, just count how many zeros you have and move the decimal to the RIGHT!
When dividing a decimal number by Powers of 10, just look at the exponent or count how many zeros you have. Then, move the decimal to the LEFT!
