Equations of Parallel and Perpendicular Line
Lesson 1: Our lesson plan was a type of guided discovery lesson that tries to pull real life examples. The students are going to take pictures of parallel and perpendicular lines around campus. Students need flip cameras and laptops equipped with GSP. The lesson is set up to use a document camera, but this can be adjusted based on the technology available to you. Students should also have graphing calculators available.
Lesson 2: Our lesson plan was more of a guided-discovery and focused on the manipulation of triangles in order to discover the slopes of parallel and perpendicular lines. The students worked individually for the majority of the time with the exception of working in pairs during the brief Check for Understanding. Very little technology involved--the lesson is guided with a PowerPoint (but this can be changed/printed) and the only other materials required are scissors and graph paper.

Lesson 7: This lesson uses a warm-up to transition from analyzing a single line to analyzing the relationships between two or more lines. The students will find the equation which represent the given lines. They will then be lead in an investigation of whether the lines are parallel or perpendicular. Using their assumptions, the class then examines how slope is used to determine those relationships. It relies upon the misconceptions that students may use because of their preconceived and instilled ideas. After analyzing those lines given in the warm-up, the students are shown a single graph with five lines. Again, they will make assumptions which will be confirmed or disproved during discussions. Finally, the students will investigate parallel and perpendicular lines using slope in the worksheet below. They are asked to determine if there is a relationship between two functions and to also find an equation which satisfies certain criteria.

Lesson 9: The lesson is a hands-on (potentially out of seat) guided discovery type activity that guides students towards discovering how to determine if two lines are parallel or perpendicular given their equations, graphs, or both. If you have a smaller class (~20 or less) and room to spread out, this lesson requires a roll of masking tape and some string or yarn. But if you have a larger class, you can just use poster-board and some string.

This activity uses a TI 84 or 83 to have students see what happens to Absolute Value Functions as the parameters a, b, and c change. The activity is designed for students who have not had any experience with the graph of an absolute value function.

All I Have to do is act Naturally
This activity is designed to help students explore the untamable wilderness that is Exponential and Natural Log functions. They will use graphing calculators to try and match equations with their plots and then when given an equation they will practice sketching the graph of the function. I am not going to lie. It is awesome. Seriously. And awesome does not just mean uber cool. It also stands for Acquiring Wisdom Exponentially So Often, Mathematics Explodes. That is all.
