**Base Ten Place Value System (clap and show 10 finger)**

**Nine digits: 0,1,2,3,4,5,6,7,8,9 (use fingers to show digits)**

**Make all numbers to infinity great and infinity small (stretch out horizontally with both arms)**

**To the Right , decrease (stretch out right arm in diagonal going down)**

**To the Left, increase (stretch out left arm in diagonal going up)**

**The decimal point separates whole numbers and parts**

**X10 or 10 to the first power increase by one place (show 10 fingers, both arms go up)**

**X100 or 10 squared increase by two places (show 10 X 10 fingers, both arms go up to the left diagonal twice)**

**X1000 or 10 to the third power, increase by three places and so on. (show 10 X 10 X 10, both arms go up to left diagonal three times)**

**Divide by 10 or X 1/10 decrease by one place (10 fingers down, arms go down right diagonal)**

**Divide by 100, 10 squared or X 1/100 decrease by two places (10 X 10, " two times)**

**Divide by 1000, 10 to the third power or 1/1000 decrease by three places (10 X 10 X 10 three times ")**

**Multiply by Whole Number (positive) Exponents**

**Move Left with the Number -- moves places equal to the exponent**

**Right with the Decimal -- move places equal to the exponent**

**Increase**

**Divide by Whole Number (positive) Exponents**

**Move right with the Number -- move places equal to the exponent**

**Left with the Decimal Point -- move places equal to the exponent**

**Decrease**

CCSS.Math.Content.5.NBT.A.1 Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left. |

CCSS.Math.Content.5.NBT.A.2 Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10. |
