studying the civilizations of the Mayans, Aztec, and Incas.  This is a great opportunity to work on the concept of comparing and contrasting.       

• Geometry - Mr. Kjellsen
• The Geometry classes recently completed a unit on perimeter and area. They found the perimeter and area of various different polygons. They are now working on 3-dimensional geometry. They will draw and find the lengths of different 3-D shapes, such as prisms, pyramids, cylinders, cones, and spheres. They will also find the surface area and volumes of these shapes.

• Algebra II - Mr. Kjellsen
• The Algebra II classes just completed a chapter involving radicals and exponents. They are simplifying expressions and solving equations involving radicals. Their next chapter begins the Trigonometry portion of the class. Trigonometry, by definition, means triangle measure. They will learn various trigonometric ratios they can use to find different sides and angles of triangles. They will also graph trigonometric equations.

• Trig/Precalc - Mr. Kjellsen
• The Trig/Precalc class just completed the unit on integral calculus. This study of calculus involves integration and finding anti-derivatives. They found areas of different 2-dimensional shapes and volumes of 3-dimensional shapes using integrations. Their next chapter involves statistics and probability. They will find different permu
