Reflection: Diverse Entry Points Systems and Parallel Lines - Section 1: Launch


I started this lesson with an entrance ticket, which students had to solve each system, make comparisons and inferences. In the past, I've started the lesson by simply asking questions like, "how many solutions can a system have?" Students will usually say ONE. I follow by asking the class if a system can have NO solution, leading them to come up with parallel lines,,,,and so forth. Yet, I've found that just asking these question without any tangible resource did not work well with many students, and kind of left them "up in the air", including ELL kids.  Although the questioning is good, I could have given the same questions on paper, maybe with graphic images. The entrance ticket here has given me better results although it takes more time.

Systems and Parallel Lines

Unit 6: Systems of Linear Equations
Lesson 8 of 13

Objective: SWBAT determine whether a system has 0, 1, or infinitely many solutions.

Big Idea: Systems having 0, 1, or infinitely many solutions correspond to lines not intersecting, intersecting once, or being coincident.
