1 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.
2 Essential Questions 1. 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?
3 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.
4 ObjectiveI can divide decimals to hundredths place.
5 Decimal - a number with a fraction of tenths, hundredths, etc 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.x =Let’s Review Again
6 Rules for Dividing Decimals To divide decimals, divide as you would with a normal whole number then you move over the decimal.
8 Divide as with whole numbers. Dividing DecimalsExample 2Solve = 2.25 ÷ 2.52.5)2.25-0225Divide as with whole numbers.
9 Dividing Decimals Divide as with whole numbers. Example 2 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 ÷ 2.50.925)22.5-0225-225Answer: 0.9
