Algebra I

Before spring break we learned how to solve a system of equations using substitution. Now we are learning a new method called elimination. The purpose in learning how to solve a system of equations is so we know how to solve a problem like: You are baking 2 different types of muffins. Muffin A uses 4oz of flour and 2oz of milk. Muffin B uses 3oz of flour and 1oz of milk. You have a total of 165oz of flour and 75oz of milk. How many muffin A‘s and muffin B‘s do you need to make in order to use up all of your flour and milk?

Geometry

We are still learning about trigonometry and some of its practical applications. We have not started the project where we use trigonometry to measure the height of a building, but we will very soon. After trigonometry we will start our final lessons of the year, solid geometry.

Algebra II

We have just finished learning how to factor quadratic expressions and how to solve quadratic equations by factoring. We are now learning how to solve quadratic equations by completing the square and using the quadratic formula. After our lesson on quadratics we will start to study conic sections: circles, ellipses, parabolas, and hyperbolas.

Pre-Calculus

Before spring break we started our lesson on trigonometry. We have been doing what the geometry class has been doing for the past month. However, after we measure the height of the building using trigonometry we will continue with trig and delve deeper into trigonometry than we will in geometry.
