The various resources listed below are aligned to the same standard, (6EE02) taken from the CCSM (Common Core Standards For Mathematics) as the Expressions and equations Worksheet shown above.

*Write, read, and evaluate expressions in which letters stand for numbers.*

*Write expressions that record operations with numbers and with letters standing for numbers.**For example, express the calculation "Subtract y from 5" as 5 - y.**Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity.**For example, describe the expression 2 (8 + 7) as a product of two factors; view (8 + 7) as both a single entity and a sum of two terms.**Evaluate expressions at specific values of their variables. Include 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).**For example, use the formulas V = s*^{3}and A = 6 s^{2}to find the volume and surface area of a cube with sides of length s = 1/2.

- Solving Simple Equations #1 e.g. 5n = 40 (Note: Just 2x, 5x, & 10x facts required)
- Writing equations (1 of 2) e.g. t + 3 = x
