| Part 4: Working on the Problem Together [Begin: 15:49]
|
The teacher asks for a volunteer to work the problem on the chalkboard. The volunteer begins working the problem by recording the given information. The teacher monitors the ensuing 20 minute discussion on how to solve the problem. The student at the board tries to solve the problem while taking suggestions and corrections from the students at their desks. One student says "I would convert that into centimeters." The volunteer responds "I wouldn’t." The teacher says, "Would you give him a reason" and the student says, "Well, then the numbers are a little bigger and the density would be easier to calculate." During this activity, several other students take their turn at the board. The activity concludes when the students agree on the answer. | ||
