Phase: | During/Explore/Explain |
Activity: | When teaching the lesson whole group: 1. Access the Geogebra lesson Getting to Know the Cartesian Plane with students. 2. Take time to walk students through the vocabulary in the lesson: x-axis, y-axis, ordered pair, coordinates, origin, and quadrants. 3. Use the first applet to demonstrate the four quadrants to the students by clicking the checkbox for each quadrant. When you click the checkbox, the corresponding quadrant will change colors. 4. Answer the questions below the applet together: What property do all the points (x, y) in the first quadrant have in common? the second quadrant? the third quadrant? the fourth quadrant? Hint: It has something to do with the signs of the coordinates. 5. In the second applet, test the students' understanding of the rules governing the signs of the coordinates of points by answering the questions. This can be done by having the students hold up one finger for Q1, two fingers for Q2, three fingers for Q3, four fingers for Q4, make an X for the x-axis, make a Y for the y-axis and make a B for both x and y-axis. (or whatever hand signals the teacher decides to use). |
Assessment Strategies: | The students will be assessed using the applet from the lesson in the learning activity. The applet will test the students' understanding of the rules governing the signs of the coordinates of points on the Cartesian plane. (When teachers are signed into their account, student results will be visible.) |
Advanced Preparation: | Geogebra is free for teachers. To access all resources, teachers need to create a free account. Creating a free account will allow teachers to be able to assign interactive & engaging tasks to students. Teachers will be able to view live updated progress of students working on a specific task and view which tasks students have (or have not) started. Teachers will be able to ask the entire class questions and see all students' answers instantly. Teachers who are not familiar with Geogebra can find a complete tutorial for Geogebra Classroom here. |
Variation Tips (optional): | This learning activity can be used as a whole group activity, partner activity, or assigned as an individual activity. If assigned individually, or as a partner activity, teachers will want to create a free account and share the lesson with students. |
Notes or Recommendations (optional): | This learning activity can be used with the following activities: Introducing the Four Quadrants of the Coordinate Plane (before) Finding the Four Quadrants (after) |
