Overview



Students will:
  • build on their understanding of order of operations.


  • use the properties of operations to rewrite equivalent numerical expressions.
  • understand that the properties of operations hold for integers, rational, and real numbers.
  • use variables to represent real-world situations and use the properties of operations to generate equivalent expressions for these situations.
  • experience expressions for amounts of increase and decrease.
  • use substitution to understand that expressions are equivalent.
  • use and understand the properties of operations which include: the commutative, associative, identity, inverse properties of addition and of multiplication, and the zero property of multiplication.
  • understand the connections between performing the inverse operation and undoing the operations.
  • show their steps in their work and explain their thinking using the correct terminology for the properties and operations.
  • build upon their understanding and application of writing and solving one-step equations from a problem situation in order to understand and solve multi-step equations from a problem situation.
  • practice using rational numbers including: integers, and positive and negative fractions and decimals.
  • analyze a situation and identify what operation should be completed first, and then find the values for that computation.
  • work with multi-step problem situations that have multiple solutions and therefore can be represented by an inequality.
  • understand that values can satisfy an inequality but may not be appropriate for the situation, therefore limiting the solutions for that particular problem.


Vocabulary

* Variable: A symbol, usually a letter, which is used to represent one or more numbers.


  • Numerical expression: An expression consisting of numbers and operations.


  • Algebraic expression: An expression consisting of at least one variable and also consist of numbers and operations.


  • Term: A number, a variable, or a product and a number and variable.


  • Coefficient: The number part of a term that includes a variable. For example, 3 is the coefficient of the term 3x.


  • Constant: A quantity having a fixed value that does not change or vary, such as a number. For example, 5 is the constant of x + 5.


  • Equation: A mathematical sentence formed by setting two expressions equal.


  • Inequality: A mathematical sentence formed by placing inequality symbol between two expressions.

7.EE.3. Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies.
