Guzinta Math: Powers and Exponents

Math lesson app for teaching properties of powers. 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 properties of powers and operating with powers that have positive and negative exponents--key concepts in 8th grade. NEW 5.0 version contains a slicker look, an interactive module exploring musical ratios and possibly fractional powers of 2, and extra practice questions which appear progressively over 3 weeks from starting the app. This lesson app 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: Powers and Exponents focuses on the Product of Powers Rule, Quotient of Powers Rule, and Power to a Power Rule, as well as properties of powers with negative exponents and the special conceptual meanings for powers with exponents of 0 and 1. For one-on-one or whole-class mathematics instruction, use this Guzinta Math lesson as a supplement for teaching properties of powers and positive and negative exponents--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 canvas feature in the app to write all over the screen--take notes, highlight key terms and ideas, show work, etc. Guzinta Math: Powers and Exponents includes a module that addresses the meanings of exponents and powers and multiplying and dividing with powers that have the same bases, a module that then folds negative exponents into the mix of multiplying and dividing, and finally a module which includes powers of powers as well as all the operations.
