Getting the Project Ready

Title: Graphing Functions

Concept: graphing functions using a table

General Goals: Math Common Core State Standards A.REI.10 Understand that the graph of an equation in 2 variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line).

Specific Learning Outcomes: Students will be able to graph an equation in 2 variables in the coordinate plane by completing a table.

Characteristics of Learners: The learners will be three different sections of 8^th grade Accelerated Math. The first class has 10 people, 6 boys and 4 girls. The second class has 20 people, 11 girls and 9 boys. The third class has 17 people, 10 girls and 7 boys. The school is located in a rural community in Adams County.

Required Materials:

• iPads (provided by the school)
• video viewing devices at home
• Edmodo.com
• todaysmeet.com
• graph paper/worksheet

Introduction: This will take place the last 15 minutes of class.

Graph the following coordinates in a coordinate plane. Compare with your table-mates when you're finished. A(2,3)    B(-6,0)    C(0,4)    D(-5.-2)

This will remind the students about coordinates and how to use the coordinate plane. Then different students will come up to graph each of the coordinates. We will discuss different aspects of the coordinate plane throughout the student led examples.

Step-By-Step Procedures: The teacher will make a video about how to graph an equation with 2-variables using a table. She will post it to Edmodo. Outside of class, the students will watch the video. Then, they will answer a question on Edmodo to indicate what they learned. 

The morning of the next class, the teacher will check the students' responses on Edmodo to decide what direction to take the class that day. If most students didn't understand the concept, the teacher will re-teach the lesson to the class. If most of the students understood the concept, the teacher will only discuss the process with the people who struggled.

The students will work on a worksheet that has equations for them to graph for the first 15 minutes during class time. They can ask their neighbors for help, compare answers, refer back to the video, ask a question on Today's Meet, or ask the teacher for help. After the first 15 minutes, the students will use Edmodo to write an explanation of how they can go from an equation to a graph. Then, we will do a short activity to get the students thinking about the next concept. 

Assessment: Students will complete a worksheet and they will explain the process on Edmodo. 

Conclusion: No matter what kind of function you have, you can always use a table to find coordinates to graph that will then represent the function.
