As the students enter the classroom, be sure to have the PowerPoint displayed with the opening problem slide active. I also provide a half sheet of paper with the problem written on it so that the students don’t have any excuse to get started!
Randy’s house is one mile from the school. He starts walking to school one day, goes half the distance from home to school and stops. He turns around, heads home, goes half the distance from the point where he turned around and his home, and stops. He turns around, heads toward school, goes half the distance from where he turned around and school, and stops. He turns around, heads towards home, goes half the distance from where he turned around and his home, and stops… this continues for a LONG time!
1) Stand up and act out the scenario in our classroom. Perform at least 5 turns.
2) Draw on your half sheet of paper the scenario that you just acted out.
3) Compare scenario drawings with 2 people around you.
4) Calculate Randy’s limiting position(s)
A few notes:
As the students are working on the Opening Activity, rotate the classroom to check and see how last night’s homework assignment went. (As it states on the PowerPoint Slide, the students should have this out and ready for you to take a look at.) This will give you a picture as to how the second phase of the lesson will go, and what types of questions you can anticipate from the students.
