Common Core For Grade 6

Examples, solutions, videos, and lessons to help Grade 6 students learn to write, read, and evaluate expressions in which letters stand for numbers.

A. 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*.

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*.

C. 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.

Common Core: 6.EE.2

### Suggested Learning Targets

**Writing Expressions (6.EE.2)**

Turning Words into Math

Examples:

1. Add t and 7

2. The sum of 4 and 3x

3. Subtract 8 from r

4. 8 less than 2r

5. The product of 3 and x

Multi-step examples:

1. 4 less than the product of 3 and t

2. The sum of a and the product of 6 and y

**6.EE.2.a - From Words to Expressions (Less than and Difference)**

Translate from words to algebraic expressions.

Examples:

1. What is nine less than seven times a number m as an expression?

2. Write five times the difference of 6 and a number x as an expression.**Identifying Parts of Expressions (6.EE 2)**

Term: A part of an expression, a number, variable (or numbers and variables multiplies by each other) separated by addition of subtraction from other terms.

Coefficient: The number multiplied by a variable. Evaluating Expressions and Order of Operations (6.EE.2)

Examples:

1. Evaluate 3x for x = 5.

2. Evaluate 100 - 2b^{2} for b = 3.

3. Evaluate 3(2a - 3) for a = 9.

Using formulas to evaluate.

Example:

V = lwh Find the volume of 5 of these rectangular prisms that each have l = 3 cm, w = 2 cm and h = 4 cm.
