Guzinta Math: Multiply and Divide Negatives

Math lesson app for multiplying and dividing negatives. 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 multiplying and dividing with negative numbers--a key concept in 7th grade. NEW 5.0 version contains a slicker look and a new short module on determining distances between integers and other rational numbers on a number line using absolute value. 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. The 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: Multiply and Divide Negatives focuses on modeling the multiplication of signed numbers and why a negative times a negative is equal to a positive. Students also determine distances between rational numbers on a number line and connect the ideas around multiplying with signed numbers to discover how division works with negative numbers. In the interactive module, the concept of slope is presented, which students explore using an interactive graphing tool. Students use contexts and the interactive grapher to see how the ratio of the change in y to the change in x can represent a situation as the slope of a line modeling the relationship. For one-on-one or whole-class mathematics instruction, use this Guzinta Math lesson as a supplement for teaching multiplication and division with negatives--a key concept 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 in the app to write all over the screen--take notes, highlight key terms and ideas, show work, etc. Guzinta Math: Multiply and Divide Negatives includes two modules that directly address multiplying and dividing with negative numbers--including fractions and decimals--a module on determining distances between numbers on a number line using absolute value, and a module exploring the slopes of lines using an interactive graphing tool.
