BEFORE: Graphic Organizer

1. Students will fill in the appropriate spaces.

2. The teacher will then teach/review explicit instruction (I Do, You Do, We Do, Ya'll Do) how slope is related to linear equations.

DURING: Collaborative Groups/Graphic Organizer

1. Students are already in their assigned groups or stations. Students will be given needed materials.

2. The teacher may demonstrate dropping the penny on the graph paper if needed. Students will then drop two pennies simultaneously. Wherever the pennies land, students will mark their graph paper labeling the coordinate points.

3. Next, students will draw a line connecting the two points and proceed to find the slope of their graph. Ensure their lines cross the y-axis. Once students, have found the slope for the line, they then can write their linear equation in slope-intercept form.

4. Students should be able to identify and explain the slope and y-intercept. Monitor students progress and ask leading questions (i.e., How does finding the slope of a line help you identify the direction of the line?). Students will repeat the same process for the second linear equation.

5. While two of the group members are working on the graph, the timekeeper and recorder should work on providing an explanation of the process of writing a linear equation and compare it to the graph on the graphing calculator (See scoring rubric).

AFTER: Think-Pair-Share - This is to be done within the group.

1. Have groups to share what they found or noticed in the process of writing their linear equations. They may state any difficulties as well.
