    GROUP GOALS

    Each of these terms is an important component in developing a student’s mathematical reasoning ability.  The class goals will be to reflect the different stages of the reasoning process as follows.  

    Investigate/Explore - Students will be given situations in which they will look for patterns or relationships between elements within the setting.

    Discover - Students will observe relationships of perpendicularity, similarity after an investigation or exploration.  

    Conjecture - Students will make an overall statement, which they think is true, about the new discovery. 

    Reasoning - Students will engage in a process that leads to knowing something to be true or false.  

    Argument - Students will communicate, in verbal or written form, the reasoning process that leads to a conclusion.  A valid argument is the end result of the conjecture/reasoning process.

    Justify/Explain - Students will provide an argument for a mathematical conjecture. The argument will be written as a formal proof.  

    Proof - Students will present a valid argument, expressed in written form, justified by postulates, definitions, and theorems using properties of perpendicularity, parallelism, congruence, and similarity with polygons and circles.

    Apply - Students will use a theorem or concept to solve a geometric problem.
