Ax + By — C. That’s not exactly how they teach it in grade school but with the help of Mrs. Lois Kaltsulas and Miss Karen Ostman, it all seems to make sense. Algebra I stu- dents were able to check out tapes and workbooks for extra help with various lessons. Geometry students spent the year learning postulates and theorems and working with them as well as doing proofs. Miss Ostman also took the time to teach any interested students how to use a slide rule. She and Mr. Halla took the seventh period class to Big Bend Dam as a field trip. Advanced math students, taught by Miss Ostman, were allowed to work on an individual basis. The two general math classes studied per cents, fractions, graphs, and prob- ability, under the supervision of Miss Ostman and Mrs. Kaltsulas. Mrs. Kaltsulas is always ready to give individual help. Bob Krebs shows that concentration is required for good Miss Ostman gives assistance to these advanced math students, test results.

Barb, face facts, you have to touch it sometimes! Frogs being dissected, chemicals being poured into test tubes, and, most of all, young minds learning and developing into informative memory banks. . .this is all happening in the CHS science classrooms. The classes consist of chemistry, physics, biology, and physical science, an independent study course for freshmen. With all this going on in the classroom, it makes it hard not to have any fun while learning important information in the process. The science department is headed by Mr. Frary and Mr. Merkwan. Mr. Frary oversees an experiment done by these young scientists. Ronald Frary Experiments were the principle teaching method used in physical science.
