Math lesson app for teaching proportions. Video instruction, worked examples, guided practice, and instructor notes.
For one-on-one or whole-class mathematics instruction, use this Guzinta Math lesson as a supplement for introducing proportions and introducing complementary and supplementary angles--all key concepts in 7th grade.
NEW 4.0 version includes new 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.
NEW 3.0 version includes a new 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: Introduction to Proportions focuses on identifying proportions and proportional relationships by identifying equivalent ratios, cross multiplying, and graphing ratios on the coordinate plane and identifying the constant of proportionality. Students also explore complementary and supplementary angles and reason about unknown angles given complementary or supplementary relationships.
For one-on-one or whole-class mathematics instruction, use this Guzinta Math lesson as a supplement for introducing proportions and introducing complementary and supplementary angles--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.
The secondary focus of this lesson is on angle relationships, such as complementary and supplementary angles, and using these relationships to solve for unknown angles.
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.
