In pairs, students label the coordinate graph in the Think About It problem. I expect students to label the x-axis, y-axis, origin, quadrants, and the grid lines.
Instructional Note: After this lesson, students won't be expected to label every grid line. Because this lesson focuses on graphing rational numbers (rather than just integers as in the previous lesson), it is important that students are thinking about the scale on each axis.
After 3 minutes of work time, I ask a student to tell me one thing that (s)he labeled. I label that part on my exemplar on the document camera. I then ask that student to 'roll it' to another student, who identifies another piece that needs to be labeled. This process continues until we have everything correctly labeled.
To end this section, I ask students to identify the difference between this grid and the one we worked with in the previous lesson. Students identify that this grid has grid lines that represent decimals/fractions. I frame the lesson by stating that we will be plotting points today using rational numbers.
For the Intro to New Material, I guide students through labeling all parts of the graph, including the grid lines. Students are familiar with how to determine the scale on a number line from our work in the Integers and Rational Numbers unit. I want students to think about decimal and fraction equivalents. For this grid, I have students label the grid lines as both multiples of .2 and 1/5.
The steps students follow to plot or identify points on the graph are included in the Visual Anchor.
Students work together on the Partner Practice problems. As students work, I am circulating around the room. I am looking for:
I am asking pairs:
Before moving on to the Independent Practice, I have all students complete the final check for understanding problem independently. After 2 minutes of work time, I have students put their fingers on the point that they've graphed. This gives me a quick way to see if students are in the correct quadrant. I then have one student read his/her written response to the question.
Students work on the Independent Practice problems. As they are working, I am looking for and asking the same things as I did during partner practice.
After independent work time, I bring the class back together for discussion. I have students turn and talk with their partner about how they determined the scale for the grid lines on the second page of the independent practice. After 1 minute of talk time, I have 2-3 students share out their strategies with the entire class.
Students then work independently on the Exit Ticket to end the lesson.
