I model for students how to find the two intersections when the line intersects with the parabola. I present the last example to students, showing them a system of equations with one non-linear equation and a linear equation. I demonstrate Example 4 in the video below: What do two equations that are the same line look like?.What is the solution to parallel lines?.How many points do parallel lines share?.What would 2 equations look like if the 2 lines are parallel?.Next, I ask students to complete Practice Problems 3 and 4 from the Practice Worksheet, again as guided practice, with me assisting students, as well as students assisting peers.ĭuring this section, I also discuss the following questions with students: Students are expected to follow along during the examples and practice the calculator steps as well when I am teaching. So, in Example 4 I review how to undo the equation and solve for y. I remind students that equations must be in y= form in order to enter them into the calculator.

I repeat the same procedure as in Section 1. I demonstrate Example 1 in the video below.Īfter students complete Practice Problems 1, 2, and 3, I teach Example 3 and Example 4 from the Examples I have planned.

I allow them to help students who are slower at learning the calculator. Several students are leaders in class when using technology.

Then, I ask students to complete Problems 1, 2, and 3 on the Practice worksheet.Īs students work, I walk around the classroom to assist struggling students and peers assist others as well. I work Example 1 and Example 2 from the Examples I have planned. Once I teach this procedure, I show the students how to apply the same procedure to different types of problems. My goal is to prepare the students to use the same calculator procedure to solve a system of equations, and then a system with a non-linear function in the 3rd section. Then, my students use the TI-Nspire CX to solve the equation by finding the x-coordinate of the intersection point of the 2 lines. I teach my students to rewrite the original equation as two different equations, each a linear function in two variables. In this lesson, I first introduce how to solve a complex linear equation in one variable by analyzing it as a system of equations.
