MD.MA.6.EE. Expressions and Equations (EE)

Apply and extend previous understandings of arithmetic to algebraic expressions.

6.EE.1. Write and evaluate numerical expressions involving whole-number exponents.

6.EE.1.2. Ability to introduce squares and cubes first because they can be represented geometrically.

6.EE.1.3. Ability to extend understanding of order of operations to include exponents.

6.EE.2. Write, read, and evaluate expressions in which letters stand for numbers.

6.EE.2.b. 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.

6.EE.2.b.1. Ability to introduce and define coefficient and term.

6.EE.2.b.2. Ability to read expressions aloud to explore the concept of quantities.

6.EE.3. Apply the properties of operations to generate equivalent expressions. For example, apply the distributive property to the expression 3(2+x) to produce the equivalent expression 6+3x; apply the distributive property to the expression 24x+18y to produce the equivalent expression 6(4x+3y); apply properties of operations to y+y+y to produce the equivalent expression 3y.

6.EE.3.1. Ability to use properties of operations to simplify expressions, therefore producing equivalent expressions.
