Divide with decimalsStandard UW.GAP.5.M.NBT.07 Add, subtract, multiply, and divide decimals to hundredths using concrete models or drawing and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.

Essential Questions1.What is addition? How do you add decimals? 2.What is subtraction? How do you subtract decimals? 3.What is multiplication? How do you use a model and partial products to represent multiplying decimals? 4.What is division? How do you use a model and partial products to represent dividing decimals?

Set....Think about the strategies we use to divide whole numbers....Take turns with your face partner and describe how we multiply and divide whole numbers.

Objective I can divide decimals to hundredths place.

Decimal - a number with a fraction of tenths, hundredths, etc. written after a decimal point.Decimal point - the (.) between a whole number and fractions of tenths, hundredths, thousandths, etc.Digit- any of the numerals 0-9, which may be part of a larger number.

Rules for Dividing Decimals

To divide decimals, divide as you would with a normal whole number then you move over the decimal.

Dividing DecimalsExample 2Solve = 2.25 2.5

2.5)2.25Estimate, Multiply, Subtract, Bring Down, Start again/StopDividendDivisor

Dividing DecimalsExample 2Solve = 2.25 2.5 02.5)2.25 -0 225 Divide as with whole numbers.

Dividing DecimalsDivide as with whole numbers.

Move decimal from 2.5 (divisor) over 1 to get rid of it

Move the decimal over that same amount of spaces in the dividend.

Then move decimal straight up.

Example 2Solve = 2.25 2.5 0.925)22.5 -0 225 -225 0Answer: 0.9
