221. Positive slope2. Negative slope3. No slopeDevelopmental Activity:Lecture/Activities:1. Teacher introduces the Calculator-Based Ranger (CBR 2) by directinstruction as it is connected to the overhead. The teacher does a fewexamples of walking close to the CBR and walking away from theCBR. Then shows the students the different graphs created by the CBRof him walking. The teacher will ask the students “what do the graphslook like when I walk close to the CBR and what do the graphs looklike when I walk away from the CBR?”2. The teacher discusses why the graphs look the way they do. Forexample, as the teacher walks close to the CBR the slope is negative.3. To find slope the teacher traces the graphs that were created from theCBR and finds two random points. Then uses the slope formula tocalculate the slope of the graphs. This will be done by directinstruction from the teacher on the board.4. The students break up into groups of 3 and with their TI-83 pluscalculators and CBR they need to complete a handout. (Worksheet 1)5. The teacher will demonstrate to the students how to find the slope of alinear equation by finding the coefficient of the x term on theoverhead, from a linear equation when the students have finished theirCBR activity.Closure:1. The students will write in there journals what they learned in classabout different slopes.2. The students will turn in there journals and their handout theycompleted with the CBR, before they leave class.Assessment: Give the student’s homework on finding slopes of given points andthere will also be a writing question for the students to do. (Worksheet 2)Worksheet 1Name: ___________________________Date: ________________
23Directions:Connect your CBR to the calculator and place the CBR onto your desk.First stand 1meter away from CBR, facing away from CBR and walkaway from the CBR. Then answer questions 1-4.Now stand 3 meters away from the CBR and walk towards the CBR.Then answer questions 5-8.Lastly stand 3 meters away and stand still and answer questions 9-121. What kind of slope did you come up with? Why?2. Sketch your graph on graph paper.3. Find two points from the graph on your calculator and find the slope of the graphusing the slope formula.4.
