A Maintenance Program for Tenth Grade Mathematics

Probably no subject in the high school curriculum is receiving more attention today than that of plane geometry in the tenth grade. Much of this attention is directed towards the possibility of fusing plane and solid geometry into one course. From this situaation, one would infer that all is not well in either the field of plane geometry or that of solid, with probability in both. I think all teachers of mathematics in the senior high school are agreed that the teaching of plane geometry has not advanced to the point where we are satisfied with the results obtained.
