This packet presents students with 5 real-world linear functions. Students are asked a series of questions for each, including domain and range, discrete or continuous, writing the equation in standard form or slope-intercept form, graphing the function, and analyzing the graph.
I have included an editable Word document so you can adjust the content to best suit your class, as well as a PDF.
Here's how I used this packet in class:
1. I arranged the desks into 5 clusters and split the students into 5 groups.
2. I gave each student their own packet and provided time to work through all 5 problems with their group members.
3. I then assigned each group one specific problem to put on chart paper. I gave out markers. I set up the chart paper in advance with the group number (problem number) at the top, a half sheet of graph paper taped on, and four small boxes sectioned off at the bottom. The students transferred the work from their packet onto the chart paper in a presentable manner.
4. The students left their chart paper and markers at their cluster and took their packets with them as they rotated around to the next cluster. There, they had to compare their work on their packet to what the others put on their chart paper and provide feedback. Do you agree with everything they did? What did they do particularly well? What do you think they need to adjust? I already had a designated space at the bottom for each group to leave feedback.
5. The students continued rotating and providing feedback until they got back to their own chart paper. Then they could read and discuss the feedback from their peers.
I have heard this process called a gallery walk. I collected the chart papers at the end of the period. It was helpful for me to see their work and what the other students had to say about it. I only had to look over 5 papers instead of a whole class worth of papers. The next class, I briefly addressed any issues or conflicting ideas.
The packet can be used in many different ways -- independent work, teacher-guided notes, partner work, etc. -- but I found the gallery walk to be particularly effective!
