Eric Nelson participates in an exercise during Mike Collins' freshman honors geometry class as his sons Chuck, a freshman, and Curtis, a junior, watch him at Tuesday's open house at Battle High School. "Even I got farther!" Chuck tells his father during the exercise, which was meant to demonstrate how the left brain and right brain function differently. Collins had parents participate to better understand his expectations for the students' "interactive notebook" system.
