Lesson Plan : Coordinate Graphs with y-intercept
Teacher Name: | Doug Haan |
Grade: | Grade 9-10 |
Subject: | Math |
Topic: | graphing relations and functions |
Content: | Using y-intercept to graph lines. If time permits, I will introduce "perpendicular" lines. terms: y & x axis, ordered pairs, coordinate pairs, reciprocals(neg. & pos.), rise over run(remind that rise can be negative) |
Goals: | Students will graph lines using the y-intercept formula. After graphing lines students will find ordered pairs which cross the y & x axis. |
Objectives: | Have students demonstrate ability to find pertinent information needed to successfully graph a line from the y-intercept formula. Students will have the opportunity to use whiteboard to show work from previous days assignment. |
Materials: | graphing activity from 2-23-09, worksheet 4-4, rulers, whiteboard |
Introduction: | Ask students to describe the two ways we have used to graph lines. We first used table or charts. We then learned how to use the y-intercept method. Ask which method takes the least amount of time. |
Development: | Model using whiteboard. Explain that in today's activity they will need to find the value for y if it isn't given. If the number in front of x is a whole number it needs to be thought of as a fraction. |
Practice: | Complete first 2-3 problems from 4-4 on whiteboard. |
Accommodations: | Shorten assignment if necessary. Work independently with students if necessary. |
Checking For Understanding: | Ask students for questions or concerns with assignment. Ask students to use terms in a sentence. |
Closure: | Let students know that they will have one more day working with graphing lines and then we will begin reviewing for our exam. |
