Grade 7 - The Number System
Standard 7.NS.1.2 - Solve addition and subtraction sentences with positive and negative decimals.
Included Skills: Decimals, Mixed Equations
Students will be expected to demonstrate an understanding of the addition, subtraction, multiplication, and division of decimals to solve problems (for more than one-digit divisors or more than two-digit multipliers, the use of technology is expected). • Performance Indicators - N02.01 Use estimation to determine the appropriate place value when calculating the sum or difference. - N02.02 Use estimation to determine the appropriate place value when calculating the product. - N02.03 Use estimation to determine the appropriate place value when calculating the quotient. - N02.04 Represent concretely, pictorially, and symbolically the multiplication and division of decimal numbers. - N02.05 Create and solve a given problem involving the addition of two or more decimal numbers. - N02.06 Create and solve a given problem involving the subtraction of decimal numbers. - N02.07 Create and solve a given problem involving the multiplication of decimal numbers. - N02.08 Create and solve a given problem involving the division of decimal numbers. - N02.09 Solve a given problem involving the multiplication or division of decimal numbers with two-digit multipliers or one-digit divisors (whole numbers or decimals) without the use of technology. - N02.10 Solve a given problem involving the multiplication or division of decimal numbers with more than two-digit multipliers or more than one-digit divisors (whole numbers or decimals) with the use of technology. - N02.11 Check the reasonableness of solutions using estimation. - N02.12 Solve a given problem that involves operations on decimals (limited to thousandths), taking into consideration the order of operations.
