Review 5 th grade vocab (complete on guided notes, not warm up book): The _____________ of 12 and 3 is 15. The answer to a subtraction expression (14 minus 5) is the _____________. A(n) ____________ tells about how many. Addition, Subtraction, Multiplication, and Division are called _____________. Thousandths is the _______________ of the 1 in 42.801 Word Bank: Operations Place value Estimate Sum Difference sum operations estimate Place value Difference

Review Label all the place-values : 58,372.09 Decimal Point : 23.72 Remember Whole #s Have decimal points Ex: 65 Estimation 7.82 -2.02 (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
8
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 9.809 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.

Subtracting Decimals Ex: 29.42 – 26.213 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 0.375 = Does grouping with parenthesis matter when adding decimals? L - (24.3 + 26.7) + 5.06 = R - 24.3 + (26.7 + 5.06) = Associative Commutative
12
___________ and __________Properties Does order matter when subtracting decimals? L : 45.803 – 26.09 = R : 26.09 – 45.803 = Does grouping with parenthesis matter when subtracting decimals? L - (26.7 – 18.3) - 5.006 = R – 26.7 - (18.3 - 5.006) = Associative Commutative 3.394 -19.713 19.713 13.406
