This lesson introduced concepts of increasing/decreasing and positive/negative functions on intervals. We accomplished this by looking at a couple of graphing videos.
This lesson continued to look at functions using computer code, and helped to motivate the concept of developing a function using a vertical line test.
This very interesting lesson looks at functions from a computer programming point of view through code that gives the user instructions on what actions to perform. We will use this again in lesson 98.
Building on lesson 95, this lesson had students creating functions based on patterns, and identifying domain and range with algebraic functions.
This lesson introduced the concept of functions a slightly different way by looking at domain and range of "descriptive functions" as opposed to mathematical functions.
One of the more enjoyable lessons taught all year, we began the day by looking at Desmos.com, and then looked at patterns and tried to find formulas for each pattern. We then looked at graphs. All in all, a very complete math day!
This lesson looked at equations that had restrictions on what the variable could be as a result of not wanting to divide by 0.
A great foreshadowing for next year, we solved equations involving factored terms, and even factored a few basic trinomials.
This lesson builds on previous lessons and uses knowledge about systems and inequalities to graph systems of inequalities.
This lesson asks students to identify solutions to inequalities in two variables as half planes on a coordinate plane.
