Students will be able to...

  • Determine when it's best to use one of the slope formulas to find slope
  • Use slope-intercept form to write & graph equations or find missing values
  • Use point-slope form to write & graph equations and find missing values
  • Distinguish between positive, negative, zero and undefined slopes

1 Anticipatory Set/Hook

Since the basics of slope have already been taught in a previous unit, this lesson reminds students of the key components.

1. Teacher instructs students (in ten words or less) to write down one key item they remembered about slope on a piece of printer paper.  It can be anything they want, including a picture, or words and a picture.

2. As students finish, they will raise their hands and the teacher will come and take a picture of the student holding their "important item."  This activity will be revisited later in the lesson.  For now, the teacher will transition into the procedures.

Student Instructions

1. Write and/or draw one key item that the student remembers about slope on a piece of printer paper.  They can write or draw anything they want as long as the description remains under 10 words.

2. When students have completed part one, they will raise their hands and allow the teacher to take a picture of them  holding their important item.  This will be revisited later.

2 Procedures


1. Use a pre-created PowerPoint that includes positive, negative, zero, and undefined slopes as well as finding slope, slope-intercept form, and point-slope form,  in addition to writing equations and graphing.  This presentation should include definitions, interactive examples and opportunities for discussion.

2. Go through the PowerPoint on the Smart Board, asking students questions sporadically throughout using dry-erase boards.


3. Give students pre-created ten question Socrative "quiz" that will test their knowledge of slope.  They may work independently or with partners (if with partners, each partner must fill out their own quiz, but may work with another to get answers).

4. (While students complete Socrative activity, the teacher should create the video on Animoto for the closure activity -- upload each of the photos from the hook activity in no particular order).

Student Instructions

1. Listen to and engage in teacher's PowerPoint instruction.  

2. Answer questions on dry-erase boards when prompted.

3. Complete Socrative quiz, showing all work on a sheet of paper.

3 Closure/Wrap Up

1. Show Animoto video clip that exhibits students' "important items" from the introduction.

2. Ask students to look for common themes (which items many students seemed to remember) and some things that students may have forgotten that they now remember because of the lesson.  

3. Ask students to reflect out loud why they believe some things were remembered by many students but some things were forgotten.

4. ASSESSMENT:  Instruct students to submit a short, three to four sentence description of what they believe is/are the most important thing(s) about slope using Google Groups (teacher should have already created Google Group Discussion Board).

Student Instructions

1. View Animoto video and look for common themes and forgotten things.

2. Engage in discussion about common themes and forgotten things.

3. Write three to four sentence description of the most important thing(s) in the slope lesson on Google Groups.  Submit to teacher.
