Currently, Concord High is 10-12 high school. Starting next September Concord High School will be a 9 - 12 school. A question has come up about Algebra I classes. Currently, Algebra I classes at the Junior High are all 9th graders and the Algebra I classes at the high school are a mix of grades 10 -12 with mostly 10th graders. Next year, we were planning to open the Algebra I classes to all 9-12 grade students but it was questioned whether or not we should maintain 9th grade only classes. What do other High Schools that are now 9-12 do? Do you isolate the 9th graders or do you mix all students who wish to enroll in an Algebra I class? If you mix grades, do you feel that the 9th graders are "intimidated" by the older students?
