Title:
Graphing is Great!
Overview/Annotation:
Students will explore graphing individually and in groups. They will also use an interactive activity to discuss slope and intercepts. To assess the lesson, students will use the floor tiles in the classroom as a large sheet of graph paper to graph with slopes and intercepts.
Associated Standards and Objectives
Content Standard(s):
MA2015 (912) Algebra 46. Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data. [SID7]
Local/National Standards:
Primary Learning Objective(s):
Algebra I students will graph using equations in slopeintercept form of a linear equation.
Additional Learning Objective(s):
Preparation Information
Total Duration:
91 to 120 Minutes
Materials and Resources:
2 colors of masking tape or tempra paint, tile floor, yarn, streamer, or twine, pratice problems, and heterogeneously mixed groups.
The teacher will prepare graph board on floor using masking tape or tempra paint. Use each tile as a unit of one. Student groups will connect points with streamer or twine. (Students can also paint coordinate plane on the floor as a class project.)
Students will need graph paper, ruler, and pencil.
Technology Resources Needed:
Interactive white board, lcd projector, free Flipchart viewer (download free from promethenplanet.com ,) download Flipchart 5.4 Graphing with SlopeIntercept Form (attached) , graphing calculators,
Background/Preparation:
Teacher must visit www.promethenplanet.com to sign up for a free membership in order to download free flipchart viewer.
Students need background on coordinate planes, and graphing lines using points and slope.
Procedures/Activities:
1. Teacher will use the interactive to discuss how intercepts and slope are used in a reallife activity with the runners.
2. Teacher will teach graphing using slopeintercept form of a liner equation. Teacher will use downloaded flipchart 5.4 Graphing with SlopeIntercept Form and free viewer from www.prometheanplanet.com to work and graph examples of linear equations. Students will come to interactive white board and graph some guided practice problems.
3. Students will work in student pairs to graph on graph paper. (These problems are included at the end of the downloaded flipchart.) They will check graphs using graphing calculators.
3. Students will work in groups of 3 to graph to graph lines on the tile floor. The students will be given an equation in slopeintercept form. See attachment 5.4 Equations to use for group graphs on the floor. The students will be given time to discuss their problem and find the x and yintercepts and slope. The first student will graph the xintercept; the second student will graph the yintercept. The third student will plot a collinear point using the slope. Students will use the streamer to make the line between them. All other students watch in small groups and ask questions of graphing group.

Assessment
Assessment Strategies
Teacher observes floor graphing and grades by prepared rubric (see attachment Floor Graph rubric).
Acceleration:
Students who need extra can be asked to graph reallife linear equations using the interactive.
Intervention:
Peer tutoring will be used within heterogeneous ability groups. The interactive will help the handson learner to see the use of linear equations.
