/*Scott Nelson*/ was killed on Wednesday after his bicycle crashed into a jogger.
At a "Welcome Back to School" rally at Mount Whitney High School -- students watched a slide show of the popular math teacher.
Scott's brother, Randy, is also a teacher at Mount Whitney. He sat with Nelson's children, girlfriend, and other family members before he encouraged students to always strive for their best.
/*Randy Nelson*/ said, "One of the things that is hardest for me is that I never thought there would be a day... when there would only be one of us here."
Scott Nelson's funeral service will likely be held sometime next week.
