Systems of Equations Module (includes teacher instructions)
Module 1: Systems of Equations
Overview
This module helps students to explore the different methods of solving systems. It includes solving systems by graphing, elimination, substitution and matrices. The module also integrates the use of technology by introducing the online graphing software Geogebra. Students will be able to explore the software through a Geogebra webquest as well as an assessment. The assesmment will test the students ability on their understanding of the different methods and allow them to create connections to the specific content and real word applications.
Systems of Equations
Overview: Integrated Algebra and Tech Lessons
Education Level: Highschool, 9th grade
This module follows the Openstax Elementary Algebra 2nd Edition textbook. The following module consists of 3 lessons of content, a Geogebra introductory webquest and a small systems of equations project assessment. The lessons are written as followed:
- Graphing Systems of equations and substitution
- Solving systems by elimination and matrices
- Systems applications
- Geogebra webquest
- Systems project/assessment
The first lesson consists of learning the different solutions of systems of equations using graphing, as well as how to use the substitution method. The second lesson consists of how to solve by elimination and how to insert them into matrices. The third lesson consists of applications including a chemistry example. The 4th day consists of a geogebra quest, where students will go through a worksheet on how to use geogebra. The 5th day consists of working on the project where students are to build their own application problem, graph it in geogebra, solve by either elimination or substitution, and interpret their solutions.
The lessons are planned for 50-minute instruction. The first three lessons consists of an opener, that allows students to use their background knowledge that will help them with the lecture. The lecture that provides instruction on how to go about the following lesson. A closure that includes problems following the lecture. These problems can be done in a group or alone. Lastly, practice problems that can be done as homework.
The lessons follow in one PowerPoint. Be sure to look at the notes written in the PowerPoint. The practice problem work sheets follow on this PDF as well as their answer keys.
This module may be used and rearranged to fit your school’s curriculum.
