6th Grade: Chapter 7 Outline

Week 14 - Week 16

Essential Questions:

  • How can algebraic expressions be used to describe situations?

Content:

Students will know and understand:

    • Variable
    • Algebraic expressions
    • Terms
    • Evaluate
    • Substitute
    • Simplify
    • Coefficient
    • Like terms
    • Equivalent expressions
    • Expand
    • Factor

Skills:

Students Will:

    • Use variables to write algebraic expressions.
    • Evaluate algebraic expressions for given values of the variable.
    • Simplify algebraic expressions in one variable.
    • Recognize that a simplified expression is equivalent to the original.
    • Expand and factor simple algebraic expressions.
    • Apply algebraic expressions in a real-world setting.

Upon completion of Unit 7:

  • 6.EE.A.2. Write, read, and evaluate expressions in which letters stand for numbers.
  • 6.EE.A.2a. Write expressions that record operations with numbers and with letters standing for numbers.
  • 6.EE.A.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.
  • 6.EE.A.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).
  • 6.EE.A.3. Apply the properties of operations to generate equivalent expressions.
  • 6.EE.A.4. Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them).
  • 6.EE.B.6. Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.
