For one-on-one or whole-class mathematics instruction, use this Guzinta Math lesson as a supplement for teaching students about the congruent angle pairs formed when parallel lines are cut by a transversal (corresponding angles, alternate interior angles, and alternate exterior angles), along with informal demonstrations of the Vertical Angle Theorem, Exterior Angle Theorem, and Angle-Angle Similarity--all key concepts in 8th grade. Students use interactive diagrams in this lesson app to demonstrate proofs of the Vertical Angle Theorem and Exterior Angle Theorem.
NEW 5.0 version has a slicker look and an interactive module on Pick's Theorem.
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!
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.
