- A possible extension is for students to design their own roof plan.
IV.NotesonAssessment
- Observe students during the presentation.
- Listen to student questions and answers.
- Be sure that the students understand how roofing and slopes are connected.
Equations of Lines
I.SectionObjectives
- Identify and write equations in slope- intercept form.
- Identify equations of parallel lines.
- Identify equations of perpendicular lines.
- Identify and write equations in standard form.
II.Cross-curricular-RampDesign
- Have a presenter from the local skate shop come in to explain ramps and how they are constructed.
- Be sure that the person that you are having as a speaker is knowledgeable about skateboard ramps and how
the ramps are designed. - You could also have someone come in who is an expert in snowboarding and ramps too.
- Ask the person to bring in some designs or ramps and compare the slope to the equation of the line.
- You can expand this after the presentation by asking the students to draw a diagram representing a skateboard
ramp and demonstrate the slope and equation of the line in the diagram.
III.TechnologyIntegration
- Have students complete a websearch on parallel and perpendicular lines.
- Students will find several different websites to explore about parallel lines and the equations of a line.
- Also, they can search for perpendicular lines and equations of a line.
- Use these websites to expand student understanding and prompt discussion.
IV.NotesonAssessment
- Assessment is done through observation in this lesson.
- You want to be sure that the students are engaging in exploring the concepts of the lesson.
- There is not a specific measureable content piece for this lesson.
Perpendicular Lines
I.SectionObjectives
- Identify congruent linear pairs of angles.
- Identify the angles formed by perpendicular intersecting lines.
- Identify complementary adjacent angles.
