Thousandths is the _______________ of the 1 in Word Bank: Operations Place value Estimate Sum Difference sum operations estimate Place value Difference

Review Label all the place-values : 58, Decimal Point : Remember Whole #s Have decimal points Ex: 65 Estimation (round to _____________ place) = 0.56 – 0.23 (round to _____________ place) =

Review Adding Decimals steps : Testmoz Step 1 : Estimate 1 st Step 2 : Line up decimals Step 2b : Insert zeroes as placeholders (not required, but helpful) Step 3 : Add Step 4 : Check with estimate

Practice adding more than 2 numbers with decimals 1)On Saturday, Jessica's parents gave birth to triplets and named them Christopher, Garrison, and Lee. When they were first born, Christopher weighed 8.83 pounds, Garrison weighed pounds and Lee weighed 7.02 pounds and was 18.5 inches tall. How much did the babies weigh in total? Write in a sentence.

STRETCH BREAK

Subtracting Decimals Ex: – Step 1 : Step 2 : Step 2b : Step 3 : Step 4 : Estimate 1 st ! Line up decimal points (1 st # on top) Insert zeroes as placeholders (not necessary, but helpful) Subtract Check with estimate

___________ and __________Properties Does order matter when adding decimals? 1 - The sum of 0.35, 0.375, and 1.2 = 2 - The sum of 0.375, 1.2, and 0.35 = 3 - The sum of 1.2, 0.35, and = Does grouping with parenthesis matter when adding decimals? L - ( ) = R ( ) = Associative Commutative

___________ and __________Properties Does order matter when subtracting decimals? L : – = R : – = Does grouping with parenthesis matter when subtracting decimals? L - (26.7 – 18.3) = R – ( ) = Associative Commutative
