• Fluently divide multi-digit numbers using the standard algorithm.
• Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.
• Explain when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.
• Find and position pairs of integers and other rational numbers on a coordinate plane.
• Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane including the use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate.
• Write expressions that record operations with numbers and with letters standing for numbers.
• Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient) and describe one or more parts of an expression as a single entity.
• Evaluate expressions at specific values of their variables including expressions that arise from formulas used in real-world problems.
• Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations).
• Recognize that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.
• Draw polygons in the coordinate plane given coordinates for the vertices.
