Grade 7 - Number

Standard 7.N.2 - Solve addition and subtraction word problems with decimals.

Included Skills:

Demonstrate an understanding of the addition, subtraction, multiplication and division of decimals to solve problems (for more than 1-digit divisors or 2-digit multipliers, the use of technology is expected).

• Solve a given problem involving the addition of two or more decimal numbers.

• Solve a given problem involving the subtraction of decimal numbers.

• Solve a given problem involving the multiplication of decimal numbers.

• Solve a given problem involving the multiplication or division of decimal numbers with 2-digit multipliers or 1-digit divisors (whole numbers or decimals) without the use of technology.

• Solve a given problem involving the multiplication or division of decimal numbers with more than 2-digit multipliers or 1-digit divisors (whole numbers or decimals) with the use of technology.

• Place the decimal in a sum or difference, using front-end estimation; e.g., for 4.5 + 0.73 + 256.458, think 4 + 256, so the sum is greater than 260.

• Place the decimal in a product, using front-end estimation; e.g., for $12.33 × 2.4, think $12 × 2, so the product is greater than $24.

• Place the decimal in a quotient, using front-end estimation; e.g., for 51.50 m ÷ 2.1, think 50 m ÷ 2, so the quotient is approximately 25 m.

• Check the reasonableness of solutions, using estimation.

• Solve a given problem that involves operations on decimals (limited to thousandths), taking into consideration the order of operations.
