The 2014-2015 school year is a big year for the Yucca Valley High School math department. This year the math department has seen the transition from categorized math classes to integrated math courses. After a brief interview with Ms. Siddall, she says this has proven to be the biggest challenge for her department.


This year the staff has gained two new math teachers. Mr. Cowan has joined the staff this year. He has taught math for 7 years and teaches Integrated Math 1 and geometry. Mr Agacer is a new teacher teaching math for his first year. He teaches CAHSEE, Integrated Math 1, and Geometry.


Ms. Siddall says her students are excited for upper level math classes that give them a chance to exceed and get into good colleges. The math department also works closely with many clubs on campus. Some of the clubs that the math department works closely with is Key Club, a club dedicated  to community service; AVID, which helps students prepare for college and stay organized; and of course, Math Club.


The math department teachers also possess some unique qualities. Mr. Larson handles the tech side of things on campus; Mr. Cannavo is a coach for our JV Trojan Football team; and Ms. Siddall is a member of a motorcycle club. That math department offers many opportunities for students to learn and have big challenges this year.
