Title/Topic: Writing Linear Equations                                               Grade level: High School       

Subject:  Geometry                                         Total Timeframe: 90 minutes (block schedule)       

Before the Lesson:

TEKS/Student Expectation/Key Understandings: 

Content TEKS:

• G.7.A – use one- and two-dimensional coordinate systems to represent points, lines, rays, line segments, and figures
• G.7.B – use slopes and equations of lines to investigate geometric relationships, including parallel lines, perpendicular lines, and special segments of triangles and other polygons
• G.7.C – derive and use formulas involving length, slope, and midpoint
• G.9.A – formulate and test conjectures about the properties of parallel and perpendicular lines based on explorations and concrete models

Related TEKS:

• A.1.D – represent relationships among quantities using concrete models, tables, graphs, diagrams, verbal descriptions, equations, and inequalities
• A.5.C – use, translate, and make connections among algebraic, tabular, graphical, or verbal descriptions of linear functions
• A.6.D – graph and write equations of lines given characteristics such as two points, a point and a slope, or a slope and y‑intercept
• A.7.A – analyze situations involving linear functions and formulate linear equations or inequalities to solve problems

Assessment Strategies:  How will you know the students learned the required tasks?

• Activote quiz – students will answer five questions to assess their procedural knowledge of writing and graphing linear equations.
• Individual blog – students will post a blog answering the lesson’s “essential question” to assess their conceptual knowledge of writing linear equations.

Vocabulary of Instruction: What vocabulary will be introduced and reviewed for this lesson?  How and when will this take place during the lesson?

• Linear equation – an equation whose graph is a line
• X-intercept – the point where a graph touches the x-axis; the y-coordinate is always zero at the x-intercept (x, 0)
• Y-intercept – the point where a graph touches the y-axis; the x-coordinate is always zero at the y-intercept (0, y)
• Slope-intercept form – a linear equation written as y = mx + b; where m = slope and b = y-intercept
• Standard form – a linear equation written as Ax + By = C

Materials/Resource/Tools: 

• Promethean IWB
• Promethean Activote devices
• Promethean ActivInspire software
• Internet access
• Compass learning odyssey website

Advance Preparation:  What needs to be done before the students arrive?

• Activote devices must be registered to IWB
• Create Compass learning assignment and assign students

During the Lesson:

Essential Question – How do I write a linear equation passing through a given point? (Take students through attached presentation)

1. Introduce and define new vocabulary
2. Demonstrate solving example problems
3. Assess procedural understanding/quiz (using activote devices)
4. Assign group work to be completed in class
5. Assign blog assignment to be completed for homework

After the Lesson:           What worked?  What did not work?  What changes need to be made before the next lesson?
