Guzinta Math: Solving Systems

Math lesson app for teaching systems of equations. Video instruction, worked examples, guided practice, and instructor notes.

To download all of Grades 7-8 for Windows or Mac, see https://guzintamath.com/downloads/guzintamath6.html. For one-on-one or whole-class mathematics instruction, use this Guzinta Math lesson as a supplement for teaching systems of linear equations and solving linear systems by graphing, using substitution, and using elimination--key concepts in 8th grade. Students use an interactive grapher in this lesson app to build systems according to given criteria. Students also learn to identify linear systems graphically and algebraically according to whether they have one, no, or infinite solutions. NEW 5.0 version contains a slicker look and a new brief module with practice identifying different types of linear systems based on their equations. This lesson app also includes the popular Practice Meter feature, which can keep track of each student's practice level for this app across sessions. The purpose of the Practice Meter is to motivate students to come back and revisit this content and complete modules at regular intervals. Revisit the lesson app to keep your Practice Meter out of the red (or in the blue). It becomes easier over time to maintain your practice level above the key levels of 80 or 25, because the meter depletes much more slowly after a week, then a month, then 3 months, has passed. This math lesson app also includes a NOTES feature: helpful tips for students, self-explanation questions, further information, and even suggestions for extension or family involvement--for every question and example! Guzinta Math: Solving Systems focuses on solving systems using the methods of graphing, substitution, and elimination and presents both mathematical and real-world problems which can be modeled by linear systems. For one-on-one or whole-class mathematics instruction, use this Guzinta Math lesson as a supplement for teaching analyzing and solving linear systems mathematically and in context--key concepts in 8th grade. The app includes detailed instructor notes for each guided practice problem, with notes about extending discussion around each worked example and problem. Instructors and/or students can turn on and use the new canvas feature in the app to write all over the screen--take notes, highlight key terms and ideas, show work, etc. Guzinta Math: Solving Systems includes a module in which students build linear systems according to given criteria (specific solutions, number of solutions) using an interactive graphing tool, a module which focuses on the methods of elimination and substitution, and a module in which students model and solve linear systems which represent real-world situations.
