Grade 7 - The Number System

Standard 7.NS.1.2 - Solve addition and subtraction sentences with positive and negative decimals.

Included Skills:

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).
