Learning Target(s)
“I can statements”                            I can use the properties of operations to justify that two expressions are
                                                 equivalent.
                                              I can apply the properties of operations (especially the distributive
                                                 property) to generate equivalent expressions.
                                              I can determine whether two expressions are equivalent by using the same
                                               value to evaluate both expressions.

  1. Make sense of problems and persevere in solving them.                    5. Use appropriate tools strategically.
  2. Reason abstractly and quantitatively.                                  x 6. Attend to precision.
x 3. Construct viable arguments and critique the reasoning of others.         7. Look for and make use of structure.
  4. Model with mathematics.                                                x  8. Look for and express regularity in repeated reasoning.
