# 5.NBT.7    The Powers of 10

### INTERACTIVE LEARNING for multiplying and dividing by 10’s, 100’s and 1000’s:

1. Egyptian Powers of 10 game– move up the levels  (TES website)
2. SNAPPY MATH:  Type in the Correct Product. Example:  58 tens = 58 x 10= 580
3. Kids Britannica “Powers of 10” Cross the River game .  This is pretty advanced, be ready for a challenge.
4. Math Frame quick click game. (Log in with lamar, password: lamar 123, them open this link again).  This game is more challenging!

### Exponents: 10 the the power of 3 = 1000

1. Drag-and-Drop Powers of 10 for chemistry students

## TEACHER EXAMPLES- models of the Powers of 10

1. TES Board “Place Value Shifter” model- uses a calculator model and place value grid
2. Place Value model with just digits Modeling of Multiplying and Dividing by 10, 100, etc.  You drag and drop digits, then click multiply or divide by 10, 100, or 1000
3. TOP MARKS- “Moving Digits” modeling of multi/div by 10, 100, etc (advanced in that it shows division as a multiplication of a fraction)  This uses rolling carts as a visual.

Level 1:  BASICS of multiplying by 10, 100, or 1000 and EXPONENTS

1. VIDEO: Power of 10: Patterns in multiplying by 10- intro to EXPONENTS
2. CHALLENGE- exponents:  Patterns in powers of 10 – interactive white board/pen- This included exponents.
