Guzinta Math: Linear Inequalities

Math lesson app for teaching linear inequalities. 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 linear inequalities of the form px + q < r--a key concept in 7th grade. NEW 5.0 version contains a slicker look and extra practice questions which appear progressively over 3 weeks from starting the app. The 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: Linear Inequalities focuses on modeling linear inequalities and equations on number lines and using reasoning and modeling to determine solutions. The process of inverse operations for solving both equations and inequalities emerges throughout the first two modules. In the second module, students use an interactive model to solve both inequalities and equations of the form px + q < r and px + q = r. The connection between the two processes is made as students complete these problems. For one-on-one or whole-class mathematics instruction, use this Guzinta Math lesson as a supplement for teaching linear inequalities of the form px + q < r, as well as a brief introductory exploration into the concept of probability--all key concepts in 7th 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 (with improved writing functionality) in the app to write all over the screen--take notes, highlight key terms and ideas, show work, etc.
