 * = **Lesson Topic and Description:Review of all linear equation concepts for Coordinate Geometry** =

‍ **__Focus on Concepts:I want Mickey Mouse Singlets!__**
slope, intercepts, various forms of the linear equations, parallels, ‍‍‍perpendiculars

‍‍‍‍ **__Provision for Acceleration and Compression of Content__**
1 day lesson

‍ **__Enrichment__**
generate slope and y intercept from standard forms You could give each student a card that contains one linear equation (equations would be in slope-intercept form, standard form, or point-slope form). The goal is for each student to find his/her partner. Partners could be equations that are parallel, perpendicular, or the same line. For example: Card 1: y = 2x - 7 Card 2: -2x + y = 9 Card 3: 3x - 2y = 10 Card 4: y + 5 = -2/3x - 9 Cards 1 & 2 would go together, Cards 3 & 4 together. Once the students have found their partner, they have to justify why they're partners.

‍ **__Includes In-Depth and Critical Analysis__**
relate to geometric situations parallelograms, rectangles, rhombuses find missing vertex given the other three

‍ **__Exploration of Areas of Choice__**
content self directed based on initial problem. Given a line tell me everything you know about this line Knowledge--Tell me everything you know about a given line. Comprehension--find the equation of a line perpendicular to 2x+3y=6 Application--Find the 3rd vertex of a paralelogram with vertices at (-2,-2), (0,1),(6,-2) Analysis--Compare standard form and slope intercept. Relate A,B,C with m, b. Synthesis--Prove that a given quadrilateral is a rectangle. Evaluation--Look at your neighbors argument for the synthesis question above.Comment on its validity.Make suggestions for improvement. ||  || Contributions to http://contentpd.wikispaces.com are licensed under a [|Creative Commons Attribution Share-Alike 3.0 License].
