Be sure to wear your mittens; it's cold out there!

• Geometry - Mr. Kjellsen
• The Geometry classes are just completing the unit on proving figures congruent. It is a sequential process where the must justify their conclusions using theorems, postulates, and definitions. It is one of the most difficult concepts they will do in Geometry. They are also using reflections over 1, 2, and 3 different lines to show the different ways that figures are congruent. They will be starting the chapter dealing with polygons. They will use symmetry to learn the various properties of different types of polygons

• Algebra II - Mr. Kjellsen
• The Algebra II classes are on a chapter involving solving systems of equations. They will solve equations with 2 and 3 variables by methods such as, linear combination, substitution, graphing, and Cramer's rule. It is one of the most important chapters in the book. The main purpose of Algebra should be for students to be able to solve equations. Their Christmas present will be a test over this chapter the last day of class before the break.

• Trig - Mr. Kjellsen
• The Trigonometry class is currently working on finding missing parts of right and non-right triangles. They have learned several different methods, such as, the law of sines, and the law of cosines, to find these missing parts. They are also graphing equations involving the different trig ratios. The last portion of this chapter involves solving equations with trig functions.

• Discrete Math - Mr. Kjellsen
• The Discrete Math class is a new class this year. It is for seniors who have completed all the previous levels of math. They are currently working on a unit in Logic. They use various types of reasoning to determine if various premises and conclusions are valid.

• World History - Mr. Thorson
• The year has gone so fast it doesn't seem that long ago we were just checking out books! So far in history class we have talked about the great civilizations such as the Greeks, Romans and Spanish Conquests in the new world. We just completed our journals projects which roll played my students in place of the Spanish explorers as they first saw the native civilizations in Central and South America. Us
