# 5.NBT.7 The Powers of 10

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

- Egyptian Powers of 10 game– move up the levels (TES website)
- SNAPPY MATH: Type in the Correct Product. Example: 58 tens = 58 x 10= 580
- Kids Britannica “Powers of 10” Cross the River game .
*This is pretty advanced, be ready for a challenge.* - 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

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

## TEACHER EXAMPLES- models of the Powers of 10

- TES Board “Place Value Shifter” model- uses a calculator model and place value grid
**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- 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.
