SJSD Argument Implementation Plan

Objective: G-GPE4

Essential Question: classify quadrilaterals using a coordinate geometry

Where within the unit will this lesson take place? Towards the beginning

Scenario:Graph and Classify quadrilateral ABCD with vertices A(0,-2),B(4,0), C(3,4), and D(-1,2). Use mathematical calculations and analysis to support your decision.

Resources Provided to Students (if applicable):

Resources

Graph paper/ handout of the problem

Product Expected From Students: Written document including the graph, claim, counterclaim, reasoning, and evidence (work)

Lesson Design:

Class discussion on review of parallel and perpendicular lines.Class discussion classifications of quadrilateralsGive students the handout with directions to graph, calculate, analyze, and write responses.

Extension:

Create a quadrilateral that would be rectangle and then prove it.

Create a quadrilateral that would be a square and then prove it.

Answer key:2 sample answers:

Student Friendly Version:

Graph and Classify quadrilateral ABCD with vertices A(0,-2),B(4,0), C(3,4), and D(-1,2). Use mathematical calculations and analysis to support your decision.

Assessment: Use the SJSD Revised Argument Rubric for All Content Areas

Components Proficiency Indicators Exceeds Meets Needs Revision Not Applicable

Claim: clearly states an idea or belief that is supported by evidence

*All types of argument

Establishes a credible claim.

Reasons: cause, justification, or explanation for how the evidence supports the claim

*All types of argument

Can support claim with clear, valid reasons.

Evidence: something that gives a sign or proof of the existence or truth

*All types of argument

Provides relevant and accurate evidence to back up the reasons.

Counterclaim: acknowledges other claims

*Policy Argument, Science FACT, Literary Judgment, Math FACT (if applicable)

Develops counterclaim fairly including a refutation.

Conclusion: summative statement of the argument that was made

*Policy Argument, Science FACT, Literary Judgment

Provides a concluding statement or section.
