Write and Solve Expressions with Variables
MGSE6.EE.2 Write, read, and evaluate expressions in which letters stand for numbers.
2a. Write expressions that record operations with numbers and with letters standing for numbers.
|
2b. 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.
|
2c. 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).

Review Common Multiples and Common Factors
MGSE6.NS.4 Find the common multiples of two whole numbers less than or equal to 12 and the common factors of two whole numbers less than or equal to 100.
a. Find the greatest common factor of 2 whole numbers and use the distributive property to express a sum of two whole numbers 1-100 with a common factor as a multiple of a sum of two whole numbers with no common factors. (GCF) Example: 36 + 8 = 4(9 + 2)
b. Apply the least common multiple of two whole numbers less than or equal to 12 to solve real-world problems
