Anticipatory Set“We have learned how to put an equation in y = mx + b form andhow to graph this type of equation. Let’s use this knowledge todiscover what happens to two equations with the same slope oreven similar slopes.”<strong>Lesson</strong> Body1. ExperimentingI will split the class into groups of 4 and instruct each group to assign a communicator, arecorder/time keeper, a materials person, and a reporter. I will instruct the materialssupervisor to make sure their group has 4 geo boards as well as rubber bands. I will meetwith the communicators and explain to them the following:- For each section put the 4 geo-boards together, connect them and choose youraxis near the middle.- Use a different color rubber band for each of the functions and create the graphon the geo board.- Draw the graph on the grid provided.- Once you are done with both grids, discuss the similarities of the equationsand of the graphs and try to make a general conclusion. (This includescompleting the questions for that section).2. Reflecting and ExplainingAfter the first page is complete, I will bring the group back together and ask each group’sreporter to share their findings. The reporter will use the overhead geo board to showwhat their graphs looked like. The other students will check that their graphs match thestudent reporter’s. The students will then complete the second page of the worksheet andthis will be repeated for that page. I will be sure to ask the students “what conclusions canwe make about the relationship between the graph and the equation of a line so far?”3. Hypothesizing and ArticulatingOnce each group has reported their findings, I will use these graphs and lead the studentsto a general idea of what is happening in each case. I will ask them “what are the generalsimilarities of the graphs in the first group?” “what about the second group?” I will alsoask “can you come up with a general thesis about what is happening?” Once we havediscussed both sections, I will ask the students “why do you think there is a directrelationship between a slope and graph of an equation?” and “in what ways can we besure our conclusion is correct?”4.
